Are there people who haven't seen Steven Spielberg's famous thriller "Jaws"? I think there are very few such people. I have watched this amazing movie several times. :) I was attracted to this film, because at every moment when they showed a shark approaching a person, I thought: "Thank God, it's not me!". :)

Foreign holidays every year become only more popular in our country. And here there is some concern about whether sharks are found in these resorts. I will tell you more about this. :)

Statistics

According to statistics, about 100 cases of shark attacks on humans are recorded every year. Moreover, these data come from relatively developed countries that record incidents of shark contact. On the contrary, countries in Africa seem to have a lot of attacks, but there are no services that must register all cases.


According to official data, the largest number attacks occur in , Australia, South Africa and Brazil.

What seas are sharks found in?

Sharks live mainly in warm seas. Here is a small selection:

  • Mediterranean Sea. This reservoir is suitable for habitat conditions for sharks. Thus, cases of shark attacks are periodically recorded in this sea. Over the past 100 years, 22 deaths have been recorded.
  • Aegean, Adriatic and Ionian seas. I will write about them in one section, since they are all located in the Mediterranean Sea. From 2008 to 2011, a considerable amount of terrible news about shark attacks was recorded in these seas. Only in the Adriatic Sea in 2011 there were 34 horrific cases of contact between sharks and humans.

  • Red sea. But this is true for the inhabitants of Russia. For example, I was in Egypt not so long ago, in Hurghada. This resort town is located on the Red Sea. When I splashed merrily in the water, I did not think about the possible presence of sharks. But according to statistics, about 30 species of these creatures live in this sea. And cases of attacks are periodically recorded.
  • Black Sea. Perhaps this is the safest place. The living conditions in this reservoir are not suitable for sharks, so you can safely go to the resorts of the Black Sea. :)

Wondering if there are sharks in the Black Sea? And it's not even about horror films from childhood, but about the most ordinary human concern for one's life and health.

Are there sharks in the Black Sea?

The answer to such a question can instill fear in front of ignorant people, because this answer: "Yes" and this is a scientifically proven fact.

What predators live?

You can exhale - the sharks that live in the waters of the Black Sea are practically not dangerous for humans because of their small size and caution. During the day, they hide in depth and do not interfere with their presence of vacationers.

When meeting with fishermen, Black Sea sharks do not attack them, but go to the bottom.

In addition to sharks, there are other dangerous ones in the Black Sea:

  • Jellyfish. Cornerot is dangerous, it can sting a person quite seriously with its poison;
  • sea ​​ruff or scorpionfish. It has clawed teeth and poisonous glands located on its fins;
  • sea ​​dragon. In appearance, a harmless fish has poisonous glands next to the spike on the gill cover and on the first dorsal fin, which is a great danger to people;
  • stingray stingray. There is a sharp thorn on its tail, which can grow up to 35 cm. The injection of this protective element is very painful.

Unfavorable living environment

The Black Sea is unfavorable for the life of large, dangerous sharks for a number of reasons. At a depth of about 60-70 meters, the Black Sea waters contain hydrogen sulfide, which is not suitable for the breath of most species of sharks.

And one more fact why there are no dangerous sharks in the Black Sea. Due to the lack of diversity and quantity of marine fauna, large predators simply nothing to eat in the Black Sea. The low-salinity waters of the Black Sea are not suitable for the life of large sharks that have fallen into it from.

Black Sea types of thunderstorms of the seas - photo

Only two shark species.

Katran

Also called dogfish or the Black Sea shark is the most famous predator of the Black Sea. main feature this shark has spines on its fins that are designed for protection. They are covered in poisonous slime. There are cases when a person could suffer from this shark while sorting the catch, injuring himself on poisonous spikes.

Katrans do not like solitary swimming and prefer to stray into common flocks.

The katran has a streamlined elongated shape, this allows you to develop great speed. These sharks live at a depth of up to 40 meters, a little deeper in summer, as they prefer water with a temperature of 14-15 degrees. An adult katran is no more than 160 cm long and lives for 25 years. Prefers to eat herring, horse mackerel, squid and even octopus. Avoids meeting people.

feline

The cat shark is also known as scillium. She has enough small size- an average of 60-70 cm. The body of the shark is covered with spots, which makes it similar to representatives of the feline species. Hunts in shallow water, feeds on small fish and crustaceans. Due to its size, it is often included in the diet of larger counterparts. It usually lives at a depth of 80-100 meters.

This nocturnal predator sees perfectly in darkness. During the day he prefers to lead a sedentary lifestyle. Basically, this species of sharks lives along the coast. Atlantic Ocean and in the Mediterranean Sea, from where it enters the Black Sea through the Bosporus during the migration period.

Blue, spiny and pygmy sharks can be found in the waters of the Adriatic Sea. Where is it - read in.

Sea killers and cases of attacks on people

Most of the statements that there are dangerous sharks, with relatives of fishing tales. And they belong to the most mysterious and dangerous species of sharks in the World Ocean.

goblin shark

Differently goblin shark. Perhaps the most ancient and little-studied species of sharks on the planet. The only deep sea shark. Scientists came across the bones of a goblin shark 80 million years old.

This fish acquired such an ominous name for a reason. The goblin has a large sensitive protrusion on the nose, which does not add to its attractiveness, and a mobile jaw that moves far forward at the sight of prey. It prefers depths over 300 meters and never rises to the surface. Meets Enough rarely and was considered extinct for many years.

Compared to the Black Sea sharks, the goblin has an impressive size. The length of an adult is over 3 meters.

Even the color of this shark remains a mystery, presumably it is pink, but in the event of a death of a shark, it changes to brown.

Shark has interesting features:

  1. electroreception. That is, it is capable of receiving electrical impulses from environment. This helps her to get food in the dark sea depths;
  2. She has another ability of deep-sea fish - her eyes glow in the dark greenish light.

The goblin feeds on shellfish and fish. shark in all oceans except for the Arctic, preferring warm and temperate waters. Most often found off the coast of Japan.

In December 2010, information appeared in the media that in the Black Sea in the region, fishermen was caught goblin shark. No one, except for the shark itself, was hurt. There were photos, video reports, interviews. However, experts considered the information a "duck". How dangerous the goblin shark actually is is also not known.

white torpedo

shark eater. The name speaks for itself. This is one of the most large predators on the planet. Its length reaches 7 meters. With its huge size, the shark is quite smart and curious, it has a well-developed sense of smell, which allows you to smell prey several kilometers away.

The shape of a shark resembles torpedo, which allows it to reach speeds of up to 24 kilometers per hour. Can dive to a depth of more than 1000 meters. White sharks live 60 years. Adults feed on big fish, seals, sea lions, cephalopods, can attack other sharks and even whales.

The great white shark has gained a reputation as a killer due to numerous attacks on humans. This shark lives in the Pacific, Atlantic and Indian oceans.

According to scientists, the impact of white sharks from mediterranean sea across the Bosphorus probably, but they will not swim far from the strait and coast - water temperature drops in winter and summer are not suitable for them.

White sharks are thermophilic - they live in waters heated from +12 to +24 degrees.

Here are some cases of the appearance of white sharks near the Black Sea from the world of news:

  • V 2008 And 2009 years in the area of ​​the Dardanelles in the net, fishermen from Turkey came across cubs of white sharks;
  • in July 2011 Turkish fishermen caught a juvenile great white shark in the same region;
  • in September 2016 all the same fishermen found a flock of white sharks in the Bosphorus off the coast.

blue sea queen

This type of shark got its name because of the unusual gray-blue color. The size is more modest than white, adults reach 4 meters. This species lives in the Indian and Pacific oceans. Prefers temperate and calm waters.

The blue shark is an excellent hunter, loves small fish, and in coastal waters it can attack waterfowl. This fish does not distinguish colors, but has phenomenal sense of smell.

With a man at the blue shark complicated relationship. In Malaysia, the blue shark is commercial fish and it is from there that it gets to gourmet tables different countries. But the predator herself does not remain in debt. Probability of attack especially large in the open ocean.

Less often, careless swimmers in warm lagoons can also be attacked by blue sharks.

On April 12, 2015, a blue shark attacked a photographer in south Florida, with only a bitten forearm. According to the victim, he provoked shark in pursuit of the perfect frame.

And in this video you can learn a little more about one of the Black Sea sharks:

Oceans and seas are the cradle of earthly life. All life on this planet, according to some theories, originated in water. The sea is like a kind of huge metropolis, where its own laws are established, where each Living being takes certain place and performs its important function. If this order is violated, this world may cease to exist. Therefore, it is important for everyone to know about wealth and diversity. water world and about its features.

About one of marine life this fairy-tale world can be found by reading the article. Are there sharks in the seas? What are they and what do they eat? The answers to these questions can be found by reading the information in the article.

Mysterious depths of the seas and oceans

sea ​​depths always attracted and attract people with their mystery. They have long been considered the mysterious and fabulous realm of Neptune and Leviathan. Tales of amazing unseen animals sometimes frightened the most experienced sailors.

The world ocean with its secrets and mysteries attracts both extreme sportsmen and scientists. Today, only a part of living organisms inhabiting huge water bodies is known. Among the most famous are sharks (information about where sharks are found - later in the article). Only a few of the species pose a real danger to humans.

There are others in the sea deep sea fish having unusual appearance and peculiar behaviour. Nevertheless, they are all real inhabitants of the seas and oceans.

Shark features

It is noteworthy that sharks do not have a swim bladder characteristic of ordinary fish. A variety of species of these animals have worked out for themselves a way out of this situation. For example, sand sharks draw air into the stomach, thereby creating a semblance of an organ that does not exist in them. Many use the liver instead of the bubble itself. It accumulates squalene bicarbonate, which is quite light.

In addition, sharks have light cartilage and bones, which results in neutral buoyancy. Everything else is created by the constant movement of the animal, so many varieties of sharks sleep little.

shark species

Sharks are found in the seas, which are dangerous marine animals for people. Today, scientists have more than 450 species of these predators.

There are even very small representatives of this family. For example, off the coast of Venezuela and Colombia lives a species of deep-sea shark Etmopterus perryi. Its length is approximately 20 centimeters.

Where are found big sharks? largest view- whale shark, reaching 20 meters in length. However, unlike the long-extinct megalodon, it is not a predator. Its diet consists of plankton, small fish and squid. It's pretty rare view. Its number in last years is constantly decreasing. The main threat is prey by fishermen in the countries of Southeast and South Asia, where the meat of this marine animal is eaten.

It should be noted that only four types of sharks are the most dangerous - white, long-winged, blunt-nosed and tiger. The most deadly - blunt and white. The latter can feel the blood at a distance of 5 kilometers and quietly get close to the victim. It has a specific color that makes it invisible from the surface.

Shark Diet

In food, sharks have a wide variety of preferences, and depend on the characteristics of the species and their habitats. The main food is plankton, fish, crustaceans and mammals.

For example, the white shark is more preferable to seals and sea ​​lions, but if possible, can hunt for whale mammals. This is due to the peculiarity of the teeth to cut off large pieces of flesh.

The diet of demersal shark species consists of crabs and other crustaceans. Short teeth are capable of breaking the shell. Giant largemouth and whale sharks prefer plankton and small marine organisms. Some species (such as the tiger shark) are omnivorous and can swallow almost anything that comes their way.

What seas are sharks found in?

This information is useful for those who love travel. Many are interested in where sharks live. Such anxiety is associated with concern for their safety. In fact, shark attacks on humans are rare. According to statistics, only a few species can attack a person, and the reason often lies in the fact that the fish simply does not understand who is in front of it. Yes, and human meat does not belong to the selected products of the predator.

So where are sharks found? This is a large part of the coasts that belong to the waters of the oceans. For example, the Red Sea Far Eastern seas etc.

In terms of shark attacks, according to unofficial data, countries such as Tanzania, Ghana and Mozambique are considered the most dangerous. By official statistics These include Australia, Brazil, New Zealand, South Africa and the USA. The Mediterranean Sea is home to dangerous long-winged and tiger sharks. They can swim from the ocean to the Red Sea. The Black, Azov and North Seas are completely safe in this regard.

In what seas of Russia are sharks found?

In Russia, there were practically no cases of shark attacks on humans until August 2011. The coastal Russian zone has always been considered safe in this regard. This status was lost after two shark attacks on divers. It happened in Primorye (Telyakovsky Bay, Sea of ​​Japan). The attack was carried out by a white shark. Until now, these cases are considered anomalous for the Russian seas.

It is known that most sharks mainly prefer warm seas, so the events of 2011 were associated to a greater extent with a temporary warming of the waters of the Sea of ​​Japan near Vladivostok. This event was also associated with the fact that Russian waters are cleaner in comparison with the South Asian and Chinese coasts of the Pacific Ocean. In general, the sharks of the Russian seas are extremely few and relatively safe. Only a few of them are potentially dangerous.

Where else in Russia are sharks found? Sharks for Russia are both common and unusual phenomenon. It is common that these predators live in almost all Russian seas having contact with the ocean. And the unusualness is due to the fact that it is unusual for Russians to hear about the attack of these predators in the seas of Russia.

Shark attacks in the Sea of ​​Okhotsk and the Sea of ​​Japan should not be ruled out. In the Black Sea, there can be no meetings with these predators even in the distant future, since they are far from reaching it. In this natural reservoir you can find only 2 species - katran (prickly spotted shark), as well as the feline shark (scillium). They are completely safe. Where sharks are found, only divers can be, but even so, the threat can arise only when trying to catch this sea monster with your hands. There are poisonous spikes on his skin, and the katran will not attack a person, since it is small in size (about one meter long).

Similar is the case with by the Baltic Sea, even though it is in contact with the Atlantic. Desalination of the Baltic waters is uncomfortable for the life of sharks.

In the Yellow Sea, in contact with Pacific Ocean, both the white shark and the man-eating shark can live. They can also swim giant shark and hammerhead shark. In relation to a person, they are not aggressive, but they can cause some trouble if they are frightened or injured. Yes, and the likelihood of meeting with them is minimal.

Azov, Barents and White Sea(where sharks are found) are also not dangerous in terms of attacks. Their waters are inhabited by species that feed on small fish and shellfish.

Some interesting facts

  • Many sharks are able to rest on the bottom by pumping water through their gills.
  • Only a few species of sharks regularly attack humans, and this is mainly due to prey identification errors.
  • The speed of sharks is low, since it is important for them to conserve energy, but this does not prevent them from developing high speed before attacking the intended victim.
  • Sharks, having bitten off a piece of flesh from a person, usually spit it out, since this meat for them is not the food (high in fat) that is needed to replenish energy reserves.
  • Sharks are also prone to cancer. Observation of these animals in captivity showed that their organs are also affected by cancerous tumors. Moreover, the number of cases of these diseases turned out to be much higher where the water is more dirty.

Finally

In the view of many, the shark is a lone hunter, engaged only in search of food, surfing the ocean. But such a description can be applied to only a few species. Many species lead an inactive and sedentary life.

According to recent research, some of the species have the ability to be curious, social behavior and problem solving. It is known that the ratio of body mass and brain of sharks is approximately equal to the same indicator as that of mammals and birds.

The secret has always attracted and attracts a person. The depths of the oceans have long been considered the mysterious realm of Leviathan and Neptune. Tales of snakes and ship-sized squids made the most seasoned sailors cringe. Unusual and interesting inhabitants of the sea will be considered by us in this article.

We will talk about dangerous and also giants such as sharks and whales. Read on and mysterious world deep-sea inhabitants will become more understandable to you.

Marine life

It occupies a much larger area than land. In the depths of the world's oceans lies more than one thousand mysteries that attract scientists and thrill-seekers. Today, only a part of the animals inhabiting the water column is known.

In this article we will try to briefly touch on the most You will learn why deep-sea angler has a fishing rod with a flashlight on his forehead. Get acquainted with the diversity of sharks and understand that only a few species pose a real danger to humans.

We will also consider some deep-sea fish. Photos of these unusual animals resemble fauna fantasy worlds from Hollywood movies. Nevertheless, these are real inhabitants of the ocean on planet Earth.

So, our tour begins with a review of the deadly dangerous species fish that live in the seas and oceans.

Dangerous inhabitants of the sea

In this article we are talking about a variety of marine animals. Before touching on large individuals, such as dolphins, sharks and whales, we will consider the dangerous inhabitants of the sea.

The main cause of death for unlucky divers is poisoning, and not a shark attack, as it might seem.

The most deadly can be called several types of fish. These are stone fish, puffer fish, zebra fish (or lion fish), stingray, moray and barracuda. The first three are very poisonous. The fluid contained on their spikes causes a nerve-paralytic effect. A stingray can kill with a single blow with a bone sword on its tail or electric current if stepped on an electric member of the species. Moray eels and barracudas are less dangerous, but they can confuse a diver's leg or arm with a fish and inflict a laceration. Without proper help, a person, as a rule, does not survive.

Also, a special danger lurks in the crevices of stones at the bottom and accumulations of algae. Not only the above fish are found here, but also scorpionfish, lionfish, warts and pufferfish. These animals are harmless and will never attack first. But an accidental provocation is possible due to careless touch. The fact is that they are very well camouflaged and it is difficult to distinguish them against the background of the surrounding landscape. In view of this, divers are advised to swim in pairs or groups rather than alone. In case of a sudden injection and a deterioration in well-being, you should immediately rise to the surface and consult a doctor.

In the course of the article, you will see photos of the inhabitants of the sea. These will be giants and dwarfs, unusual anglers and fish in the form of aspic.

shark species

The most dangerous inhabitants of the seas are sharks. Today, scientists have more than four hundred and fifty species. You will be surprised, but there are very small representatives of these predators. For example, off the coast of Colombia and Venezuela lives the deep-sea shark Etmopterus perryi, whose length is about twenty centimeters.

The largest species is the whale shark, which can reach twenty meters in length. Unlike the extinct megalodon, it is not a predator. Her diet includes squid, small fish, plankton.

It is noteworthy that sharks do not have a swim bladder characteristic of fish. The way out of this situation was worked out by different species in their own way. For example, sand sharks draw air into the stomach and create a semblance of a non-existent organ. Most use the liver instead of the bladder. Squalene bicarbonate accumulates there, which is quite light.

In addition, sharks have very light bones and cartilage. This creates neutral buoyancy. The rest is created by constant movement. Therefore, most varieties sleep very little.

People often ask what kind of sharks in the Black Sea can attack a person. The answer is unequivocal. Only two species are found in this reservoir - katran (spotted spiny shark) and scillium (feline). Both varieties are completely safe.

Only divers can meet them face to face, but even then the only threat will arise when trying to catch the katran with your hands. It has poisonous spines on its skin. They will not attack, since the person is larger than them. The length of these varieties ranges from about a meter.

What seas are sharks found in?

This information will not interfere with those who are going on a trip. Tourists are often interested in the question in which seas sharks are found. Usually such excitement is caused by concern for one's safety. In fact, a shark attack on a person is a rather rare event.

Statistics say that only a few species of sharks attack people. And the reason is often that the fish did not figure out who was in front of it. Actually does not belong to the selected products of this predator. Studies say that after biting into it, the shark usually spits it back out, because it does not belong to the high-fat food that it needs.

So how many seas can become a refuge for dangerous predators? These are the majority of coasts that are directly related to the waters of the oceans. For example, Far East and others.

Only four types of sharks are considered the most dangerous - long-winged, tiger, blunt-nosed and white. The last two are among the most deadly. White shark- one of the most powerful predators. She can feel a drop of blood at a distance of five kilometers and sneak up on the victim unnoticed. All this is due to the specific color that makes it invisible from the surface.

Ghana, Tanzania and Mozambique, according to unofficial statistics, are considered the most dangerous countries about shark attacks. According to official data, these include Brazil, Australia and New Zealand, the USA and South Africa.

In the Mediterranean Sea, among the most dangerous species, there are long-winged and tiger sharks. These same fish can swim from the ocean to the Red Sea. The northern seas, as well as the Black and Azov, are completely safe in terms of attacks on humans by sharks.

whale species

The largest inhabitants of the sea are whales. Today, despite their impressive size and enough large populations some species, animals are little studied. Every year there are unexpected discoveries of new units or specific habits.

On this moment scientists know about eighty species of whales. Readers will no doubt be interested to know that the closest relative of this mammal is the hippopotamus. In addition, initially whales lived on land and were artiodactyls. Researchers say that the ancestor of these giants descended into the water about fifty million years ago.

Biologists distinguish three orders of cetaceans - toothed, baleen and now extinct ancient whales. The former include all types of dolphins, sperm whales and porpoises. They are carnivores. Feeds on cephalopods, fish and marine mammals like seals and cats.

Baleen cetaceans, unlike the first, do not have teeth. Instead, they have plates in their mouths, better known as "whalebones". Through this design, the mammal draws in water with small fish or plankton. The food is filtered out, and the liquid is thrown out through a special hole in the form of the famous fountain.

These are huge animals. The largest of the baleen whales is the blue whale. Its mass reaches one hundred and sixty tons, and its length is thirty-five meters. In total, researchers count ten species. These are blue, gray, pygmy, humpback, southern and bowhead whales, sei whale, fin whale and two subspecies of minke whales.

As you can see, the sea and its inhabitants keep a lot of interesting secrets. Let's see where these giants are found.

What seas are whales found in?

For example, whale lice can cause ulcerative sores on the body of these giants.
Among minke whales, it is the above-named individuals that are the most frequent inhabitants of the seas.

The names of the water bodies in which they swim are as follows: White, Barents, Greenland, Norwegian and Baffin Seas in the Atlantic and Chukchi in the Pacific Ocean.

The blue whale is known today in four varieties. Its northern and southern species live in the cold seas of the respective hemispheres, while the dwarf and Indian species tend to live in tropical latitudes. Because of special interest this animal was practically exterminated by the middle of the twentieth century. In 1982, a moratorium began to be introduced. Today, about ten thousand individuals are known in the world.

Thus, whales, like dolphins, whose photos will be presented below, live in almost all areas of the world's oceans and in marginal seas. They do not swim in inland waters like the Mediterranean and Red Seas due to insufficient depth and lack of necessary food.

Dolphin species

Undoubtedly, the most popular and human-friendly marine life are dolphins. Photos of these mammals will be presented below.

To date, about forty varieties are known. Eleven of them live in the waters of the Russian Federation.

If we divide these marine inhabitants into genera, we get a rather interesting picture. There are motley, gray, black, as well as Malaysian, Irwadi, humpback and large-toothed dolphins. There are humpbacked, long-beaked, beaked, short-headed and protodolphins. This also includes killer whales, small and pygmy killer whales and bottlenose dolphins.

In particular, it is the latter type that is the most promoted in literature and cinema. With a high degree of probability, the inhabitants at the word "dolphin" will remember a representative of this species.

But not all dolphins are sea dwellers. There are four river species. They have poor eyesight and weak sonar. Therefore, these mammals are on the verge of extinction.

For example, Amazonian river dolphin It has a pink color and is considered sacred by Indian tribes. These amazing creatures also live in the Ganges, Chinese rivers and La Plata.

If speak about external signs this animal, the following can be mentioned. They are capable of reaching two meters in length, pectoral fins - about sixty, and dorsal - up to eighty centimeters long.

The number of teeth in dolphins is not constant. It varies from one hundred to two hundred. It is noteworthy that there are quite large flocks of these mammals, up to several thousand heads.

Some amazing facts about dolphins. Their brain is three hundred grams heavier than a human. It also has twice as many convolutions. They have the ability to sympathize, and their "dictionary" has up to fourteen thousand different sounds. Signals are sonar (for orientation) and communicative.

Man uses these mammals for both peaceful (pet-therapy) and military (mine detection, kamikaze for submarines) purposes.

What seas are dolphins found in?

How many seas on the planet, so many habitats different types dolphins. But their range is not limited to such reservoirs. They live in rivers and in the open ocean.

Dolphin species vary depending on the sea temperature. For example, in the colder northern latitudes, the so-called "northern" representatives live. These include belugas and narwhals, or sea unicorns.

The former live in places where there is no permanent ice crust. They are not able to break through the thickness of frozen water. In cold winters, beluga whales migrate south to the Baltic or the Sea of ​​Japan. It is noteworthy that this species cannot be without breathing for more than fifteen minutes, so they do not dive deep. Also, beluga whales do not jump into the air, like their southern counterparts. The breathing hole has time to become covered with a crust of ice even in the second that they inhale.

Narwhals are more adapted to northern conditions. The tusk, for which they are called unicorns, is an exaggerated version of the tooth. Usually it is in males, and most often on the left side, although they are also found with two tusks.

Narwhals break open holes with their horns so that unarmed females and cubs can breathe. Therefore, they constantly stay in herds.

However, the southern varieties are more popular. A photo of these mammals adorns many logos and is replicated in various industries. Dolphin representatives warm seas acted in films, they are admired by tourists. Also, these animals are used for therapy.

They can be found in any sea from temperate latitudes to the equator. But the most famous is the Atlantic bottlenose dolphin. They reach four meters in length, consume about fifteen kilograms of fish per day. Easy to train, non-aggressive, on the contrary, very friendly.

Main difference ocean dolphins from marine - in the depth of immersion and the ability to do without oxygen longer.

The magical world of the Black Sea

Now we will touch upon the fauna of one of the most interesting seas our planet. This is the Black Sea. It has a maximum length from east to west of 1150 kilometers, and from north to south - 580 kilometers. The specificity of the reservoir lies in the fact that not a single living organism is found deeper than two hundred meters, except for anaerobic bacteria. The fact is that further, to the very bottom, the water is highly saturated with hydrogen sulfide.

Therefore, fish living in the Black Sea choose the upper layers or the shelf, where bottom varieties are concentrated. These include gobies, flounders and others.

Biologists say that four times fewer different species of living creatures live in this reservoir than in the Mediterranean Sea. Of these, only one hundred and sixty types of fish. The poverty of the fauna is explained not only by the high content of hydrogen sulfide, but also by the low salinity of the water.

Cat and scorpions - the most dangerous fish living in the Black Sea. On their skin and tail there are poisonous growths, spines and thorns. There are only two types of sharks in this reservoir, which do not pose the slightest threat to humans. This (katran) and which, like swordfish, sometimes penetrates through the Bosphorus.

Also in the Black Sea there are salmon, trout, anchovy, herring, sturgeon and other fish species.

Next, we will study the most unusual inhabitants of the sea. They are different in color, structure, method of searching for prey and defense mechanisms. You will be surprised at how unlimited fantasy nature has.

The main feature of this fish is a special outgrowth on the forehead with a gland at the end. Outwardly, it looks like fishing rod, for which the monkfish is also called anglerfish. Bacteria in the gland can emit light, which flock to the fish that serve as food for this predator.

The second unusual marine inhabitant is the sack-swallower. This is a fish up to thirty centimeters in size. But he can swallow a victim four times his own size and up to ten times heavier. This ability is achieved due to the absence of ribs and the presence of a large elastic stomach.

Like the previous representative of marine inhabitants, the big mouth can swallow the victim more than he himself. The specificity of this fish is that the head with huge mouth makes up a third of his body, the rest resembles an eel.

There are also completely extraordinary deep-sea fish. You can see a photo of a drop fish below. This is an incomprehensible animal in the form of a jelly. Despite the fact that its meat is not edible and it is found only near Australia, this species is on the verge of extinction. Fishermen catch it for souvenirs.

Thus, in this article, we, dear readers, met with terrible and dangerous inhabitants seas. Learned about various types whales, sharks and dolphins. We also talked about the latitudes in which it is likely to meet them and how deadly some individuals can be.

We will tell you not only about the beaches of Australia and America, but also about the resorts of Europe and Africa that are popular with Russians!

Vacation time is in full swing. In this regard, we decided to compile a rating of resorts where man-eating sharks are dangerous for people. Nobody wants to get in trouble on vacation, right? So check out our selection now!

Predators hunt off the coast of Florida, California and the Hawaiian Islands

The beaches of Florida (US state) are considered the most dangerous in the world: here sharks attack most often. But at the same time, according to statistics, not a single vacationer who encountered a predator in the ocean died: young blunt-nosed sharks attack people. Not eaten, but seriously injured.

Off the coast of California, there are many sea lions, which are the food of sharks. Predators sometimes confuse humans with prey. You know what it leads to...

Shark attacks in Hawaii have killed Lately already 15 people. The most dangerous individuals hunt here - white and tiger sharks. Most often, attacks occur off the island of Maui. Be careful!

Australian beaches are deadly for divers and surfers

The beaches of Queensland in Australia are some of the scariest in the world. Sharks have killed 136 people in 45 years. Most often they attack surfers and peacefully swimming people. In third place attack on divers.

Killer shark attacks in the Red Sea in Egypt

In 2010, five tourists were injured in a shark attack in the resort of Sharm el-Sheikh. Four more foreigners were seriously injured on the beaches of Hurghada in 2017. Beware!

The waters off the coast of South Africa are teeming with predators who see humans only as food

The beaches of South Africa are dangerous because local sharks know that people are food. And the people who work in the tourism industry are to blame for this.

The fact is that in this country the so-called attraction is very popular - diving in a cage with sharks. As a result, this led to the fact that now people have become associated with predators with dinner.

Divers also add fuel to the fire. They feed predators from their hands. The result of such fun is terrible: in recent years, 23 people have died.

Local sharks behave in the water like real housewives. They attack not only divers, surfers and swimmers, but they can also attack a boat.

Shark sightings off the coast of Spain

In 2017, flocks of sharks, which can be dangerous to humans, appeared in the most popular resorts in Spain: off the island of Mallorca and the coast of Valencia.

Predators huddled in a group and plowed shallow water. Fortunately, there were no attacks. Perhaps they were not going to attack, or maybe the rescuers helped, who notified the tourists about the appearance of sharks.

Scientists have noticed that since 2012, often sharks began to move from the Atlantic Ocean to the Mediterranean Sea. Therefore, the appearance of predators near the beaches in these parts may soon become a pattern.
