Fear because it was a shark that usually attacks people, and respect because it is an animal that is thanks to the ability to survive survived thousands of years.

It’s fascinating that they can smeel one drop of blood in 4.6 million gallons of water. Here are 7 fascinating facts about this “incredible monster”…

Largest great white shark

The largest ever recorded great white shark in the world is known under the name Deep Blue. Deep Blue is a female, almost seven meters long (21 ft) and around 50 years old.

It was filmed near Isla Guadalupe at the Mexican Coast for the documentary of Discovery Channel, released in 2014, and it is unknown why the footage is not included in the documentary, or why the release is waiting until the present.

Great lifespan

Great white sharks live 70 years or more, that is three times longer than previously thought. Thanks to carbon dating -14, scientists have analyzed the vertebrae of four males and four females from the northwest of the Atlantic.

The biggest male was 73, and the female was 40 years old.

Amazing teeth

Great white shark has a huge sharp triangular teeth, which grow back if they are torn. At the root of the teeth there are as many nerve branches as we have in the tips of our fingers, which no one has been able to explain until now, because it turns out that the teeth of serve as a touch sensor.

It is assumed that this type of shark during life change around one thousand teeth.

Eat brothers and sisters

Young are born of eggs, but still in their mother’s womb, and, to be expected, the strongest instantly eat their weak brothers and sisters before they get out of the womb of their mother. Full sexual maturity reaches at the age of fifteen.

Swim while sleep

The sharks swim while sleeping (with open mouths), but slow – as if they were stunned. If they do not swim while sleep – they could not breathe!

Namely, while a shark swims through its gill cracks inputs and outputs of water that passes through the gills where in turn separates the oxygen necessary for their breathing.

Swim up to 25 kmh

A great white shark named after the white color that can be seen on the underside of the animal. Thanks to the body in the form of torpedoes and strong tails of large white pines, they move fast and can reach speeds of over 25 kilometers per hour (15 mph).

Three months without food

They feed on penguins, fish, seals, sea lions and dolphins. A great white shark in a year can eat 11 tons of food, but if there is no food it can live up to three months without eating anything.

The older the lines are, the more they disappear and become invisible in adult sharks.

The background color of tiger shar skin is bluish green or dark in the upper area, and the stomach is light yellowish.

They grow up to five feet, and they are scavengers who eat everything they find, from sea animals and snake to dead whales and carcass.

Killers of human
The tiger shark is considered one of the most dangerous shark species that belongs to the group of predators that attack humans. They are responsible for more than 200 attacks on people per year, of which more than 30 are fatal.

Cannibals…
Tiger sharks instinctively attack if their territory is endangered, especially at mating time. They are also prone to cannibalism. 2015 in an aquarium in Seoul a tiger shark of 2.2 meters attacked, killed and ate a little smaller “friend”.

Disappeared pummelers could see how a large tiger shark slowly drifted off his prey, and needed almost 21 hours to overcome the bite.

They can kill the whale?
Tiger sharks are one of the most dangerous in the world because they often move in shivers. In 2016 years appeared a video in which a group of 70 sharks kills and eats Humpback whale. They literally snapped it in a short time.

Sharp teeth and slow move
Tiger sharks are famous for their sharp serrated teeth that are in solid jaws and allow them unusual eating habits.

Hunting allows them to develop a sense of sight and hearing. Teeth are so sharp that ‘like saw’ can cut the armor of sea turtles.

These sharks swim very slowly and this is why they can easily approach the prey. They are particularly well-masked against dark backgrounds and can easily hunt their prey.

In 2005, fishermen in Thailand caught catfish weighing 293 kilograms (696 pounds), and length nearly 2.7 meters (9 feet). Experts say the fish, which belongs to the species known as the Mekong giant catfish, may be the largest freshwater fish ever recorded.

The biggest ever albino catfish was 2.4 feet long and weighing 88 kilograms, it was caught in Spain by Chris Grimmer in 2011.

Can live more than 100 years

Catfish can reach a length of 3-4 meters (more than 10 feet) and weighing over 300 kg (690 punds), making it the largest European freshwater fish, one of the largest in the world.

Apart from its size, this species is known for its length of life as it can experience age over 100 years. In the fourth year of life reaches sexual maturity.

Dwarf, electric and upside-down catfish

Dwarf catfish or American catfish (Amiurus nebulosus) originating in North America are considerably smaller than their cousins, European catfish. It can grow to a length of 0.5 m (1.6 ft) and a weight of about 0.5 kg (1 pound).

Electric catfish lives in the rivers of Africa. It reaches a length of 0.5 m. It is capable of producing an electric voltage of 350 V so it can be dangerous to humans.

Upside-down catfish is another specie that while young swimming has a normal body position, and when it grows swims on his back.

Catfish that catch pigeons on the shore

River Tarn runs through Albi, and there are oysters on which the pigeons come to swim and drink water. Around this island “patrol” catfish long almost a meter that has learned how to catch birds on the shore. They jump out of the water, catch the pigeon, and come back to eat their “meal”.

During the hunt they stay on the land for a few seconds. Nearly 28 percent of attempts are completed successfully. Since this extreme behavior is never noted for this species, the results of the study indicate that some individual catfish adapted their behavior to hunt new prey in the new environment.

Human bones inside stomach

In the year 2017, Polish fishermen in the Oder river caught a catfish between 90 and 110 years old. This fish was 185 kilograms / 405 pounds, but what was inside stomach of this fish it will shock you. In the huge fish were found human bones and badges belonging to the Nazi officer from the Second World War.

Studies have shown that bones found in the catfish stomach belonged to an SS officer who was killed in 1940 during the occupation of Poland. They had not yet determined whether the man was alive so the fish had killed him or was already dead when fish was eating him.

Piranhas can kill people

Although they can grow up to 43 centimeters, piranhas or certain species of piranhas can really be very dangerous, even for humans. They have extremely sharp teeth in both jaws and are able to snatch everything they find on their way thanks to a powerful jaw.

There were several attacks of this fish that finished tragic for the people. 2011 drunken 18-year-old was attacked and killed in Rosario del Jata in Bolivia. A year later, five year-old Brazilian girl was attacked and killed by a flock of piranhas of red-bellied piranhas, together with black-tailed is one of the most dangerous species.

Roosevelt has popularized piranhas

The former US President Theodore Roosevelt during his visit to Brazil in 1913 was part of a hunting expedition in the jungles of the Amazon, and local fishermen were a staged a spectacle. They were threw a cow in the water. Several minutels later cow was torned by a group of piranhas. Roosevelt later presented piranhas as dangerous creatures in his book. He stated that the piranhas is the most cruel fish in the world.

Forbidden pet

In some parts of the world piranhas can be bought as pets, although they are in many parts of the US forbidden. In the Philippines, for example, for the importation of piranhas is a sentence of six months and even up to four years in prison.

If you do decide to hold a piranha in your aquarium, you should observe some rules. They certainly should not be bought in pairs because they are aggressive and weaker of the two will not survive.

Are all piranhas dangerous?

There are about 60 species, although over the films came to fame as bloodthirsty killers, most species are scavengers and feed on plants. Only six of them posing any danger. Even 12 of the 60 species are called hermitage piranhas. That means they live only from the crumbs that fall from the other fishes (scales, fin parts).

Man-eating piranha

Black-tailed or San Francisco piranha it is the largest and one of the most dangerous piranhas. It is also known as man-eating piranha because of several recorded attacks on people. In the wild, they can grow up to 60 centimeters and in aquariums are recorded specimens of 70-80 centimeters.

Arapaima is a genus of South American tropical freshwater fish considered to be a living fossil because of its archaic morphological and anatomical characteristics. It is considered one of the largest freshwater fish in the world. The Brazilians call it the pirarucu, and in Peru it is known as paiche.

More than 2 meters / 6.5 ft
Arapaima can reach a length of more than 2 meters (in rare cases greater than 2.5 meters / 8 ft) and weighs more than 100 kg. Sometimes the largest recorded length is 4.5 m / 15 ft. This data dates back to the first half of the 18th century and is not particularly reliable.

The heaviest recorded specimen weighed 200 kg. Today, specimens of more than 2 meters are rarely seen in nature.

Labyrinthine organ

Arapaima has an expanded and elongated body in torpedo shape covered with scales and a narrowing head. Scales of adult specimens can be up to 6 centimeters long. The body has characteristic red lines. It has a special respiratory structure called a “labyrinthine organ” (so-called “primitive lung”).

Delicacy
The meat of this fish is highly valued, and the local population considers it delicacy, which certainly contributes to the fact that this meat does not contain many bones. Increased demand for meat of this fish prompted arapaime farming among “ribeirinhosim”, the local Brazilian population that living on river banks. It is also very popular among sport fishermen who consider it an excellent catch.

Guttes the air

Under water it is held for about 10 to 20 minutes only and then swims towards the surface for air ingestion. This fish guttes the air using a labyrinthine organ, and that allows the use of oxygen directly from the air. In the absence of oxygen or if it is disturbed; the arapaima often sprinkle out of the water.

This fish is known to inhabit different types of Amazonian water. It can be found in the rivers Amazon and Orinoco, their tributary rivers or floodplain lakes. Obstacles to its spread are large streams and waterfalls.

An incredible armor against piranhas

To survive in a river full of piranhas it is desirable that you have a very thick, or at least a strong scales. The scales of this fish consisting of layers like a spiral staircase, made of collagen and hard outer layer protected. Exposed pressure, the spiral layers rotate, overlap, and dissipate, thereby depleting the squeeze of piranha’s sharp teeth.

http://www.bbc.co.uk/nature/life/Arapaima

Each scale at the top is about half a millimeter thick hard outer layer, which lies below twice the thickness of the soft inner core, composed of spiral layers of collagen.

60 percent of the scales overlap each other, which is additional and definitive protection, as the scientists on the simulator studying the effect of the blades found that the teeth piranhas even could break through one layer of scabs, but not two.

Two men were mysteriously missing

In July 2009, two men were mysteriously missing at Lake Kenyir in Malaysia. Villagers from nearby villages claimed that they were killed by a huge arapaima fish, which is inhabited in that lake by calling it the “monster from Kenyira”. Apparently, several of them repeatedly saw enormous fish jumping out of the water.

Despite all that, arapaima is not considered dangerous to humans. Due to its size and tendency to jump out of the water if it is threatened; it may seem somewhat scary for the one who catch it. Therefore, it is not impossible to cause small boats to overturn or panic among fishermen, but no direct attack of fish has ever been reported.

Did you know that the hippo is one of the deadliest African animals? Exactly, is deadlier than the lions and snakes. Although it looks plump and cute, these animals can kill you in second. It is very fast when running and aggressive.

The jaws are so powerful that they can halve even a crocodile, and often attack people in boats so that break the boat with bite. They can open their mouths almost 180 °.

They give birth and use the toilet in water

They spend half of their lives in water and half on land. Although they are relatives of whales and dolphins (you read that right!) hippopotamuses can not breathe under water or dive, therefore their nostrils are located at the top of the muzzle, and muzzle always protrude above the water.

Hippos also mate, give birth, and use the toilet in water. Also are very bad swimmers, so they are always in shallow water near the shore.

Powerful bite

Hippopotamus had a strong bite, which can even penetrate the metal of which are made smaller boats. Therefore, you are not sure even in the boat when Hippo attacks.

In a zoo is measured bite of even 2000 PSI, what is 6 times stronger than the shark, 5 times stronger than wolf bite, 3 times stronger than lion, twice stronger than Siberian and Bengal tiger and also twice stronger than polar and grizzly bear. Only saltwater and Nile crocodiles have a stronger bite (5000 PSI).

Male hippos kill and eat their young

It has been reported many cases of male hippos that kill and eat their young. Scientists have not been able to find out why this is happening. There are two theories.

The first theory is that young are killed only if think they are not their descendants, as is often the case with other animals.

Second theory is that they kill the young whom they believe are weak and sick and will probably die. In this way they “make it quicker” and get a “free meal”.

Male Hippopotamus is named bull

In the group usually live about 15 individuals, and the leader is dominant male, called a bull. Usually there is just 10 females and all the mate only with a dominant male.

Sometimes may be several other adult males but they are susceptible to dominant male and should not be mated with females.

How many humans does a hippo kill a year?

Did you know that hippos kill 2,900 people annually in Africa? Yes, and it is most dangerous animal in all of Africa. Hippos kill twelve times more than lions; lions are responsible for over 250 deaths of humans each year, and also around 20% more than snakes; snakes kill 2,500 annually in Africa.

They don’t eat people, just kill them because they think that people threaten them.

They eat their dead

Eating habits of hippo are not only eating plants, but also meat. Scientists from National Geographic are with the cameras followed the herd of hippos, and found that at night, especially when the dry periods, hippos eating carcasses of other animals. Also it was noted that instead of “mourning” dead pack member, in fact; they eat them.

Of all known mammals in the world, exactly Arctic Fox has the warmest fur. Fur allows it to withstand temperatures up to -45°C.

During the winter the fur is white, and this allows it to camouflage; allows easier hunting and protection from other predators. In the spring when the snow cover melts fur changes its color to grey-brown.

Iceland native land mammal

Arctic Fox is the only native land mammal on Iceland, and is also known as the snow fox. Successfully surviving because it feeds exclusively on birds and bird eggs, but when it does not catch anything, it feeds on berries and seaweed so they may be considered omnivores.

Indigenous people eat foxes

While it is inconceivable that someone eating fox – this fox was one of sources of food to indigenous people. Nowdays, it is killed more often for magnificent fur than for food.

It is also on the menu of polar bears and wolves. But Artic Fox is not threatened and is considered to be safe from extinction because the man does not go into crude regions where this animal habitat.

Incredible ears

One of its best weapons are little but powerful ears. Located high on top of the head and forward, act as two powerful radars that detect the slightest movements beneath the snow.

Once it detects prey (usually lemmings, small rodent) beneath the snow, leaping high in the air and breaks the snow cover to reach it. Its ears are smaller than the red fox, because in this way its body loses less heat.

Death of starvation

Arctic Foxes act like nomads, annually cross thousands of miles in search of food. Since in areas where these foxes live there is not much food, main reason for death is starvation.

Each year thousands of foxes died from starvation, but it does not endanger the population because annually in litter can be up to 15 cubs.

Despite being denser than water, it can skate across the surface without breaking through. Its feet bend in such a way that the water deforms, much like elastic fi lm thanks to tiny hairs that trap air bubbles between them and the water’s surface.

Its middle legs act as paddles, making movement possible, while its long rear legs enable it to steer and even brake as it glides across the water.

Its front legs are also short enough to grab prey – living or dead – along the way. Thankfully, the speed at which the water strider can move means it stands a chance against its own predators.

A water strider catches its prey by “reading” the motion of waves that form on the water surface when an insect flounders. Recorded which of legs first touched the wave, and the time that it took him to get to the other legs. Based on that informatio water strider “calculate” from which direction the wave arrived and goes on the hunt.

Water strider facts

Short legs – Short front legs make it easy for the water strider to grab prey.

Paddle legs – Its middle legs act like paddles and enable the bug to move across the water’s surface.

Long legs – The rear legs are long and used for steering and braking.

Surface tension – The cohesive forces among liquid molecules cause surface tension.

Hair – The water strider has hairs on its legs and underside of its body that trap air.

It can jump like a kangaroo
It is not related to the dog, wolf, tiger or any other cat, but is one of the Thylacinidae family, and its close relatives are Tasmanian devils or Numbata. It is capable to perform a jump with two feet in a manner similar to kangaroos. It could balances on its hind legs and stand on them for short periods.

It was protected four months before last one died
Tasmanian tiger looked like a large, elongated dog with stripes, and the last known specimen died in a Tasmanian zoo in Hobart in 1936. Four months before it died Tasmanian government has officially decided to protect a dying breed, but is not very clear why they waited to remain a single specimen, and how they thought reproduce one Tasmanian Tiger.

One of reasons for its disappearance is a dingo
The reason for its disappearance in Australia is a dingo, a dog who came to the continent, accompanied by the first settlers, Aboriginal ancestors, and then went wild, settled the bush and, as a stronger and more advanced predator, endangered Tasmanian tiger. A similar process happens today when imported foxes seriously endanger many marsupials, some of which were brought to the brink of extinction and survive only under strict protection. Until the arrival of Europeans to Australia Tasmanian tiger has lived only in Tasmania. Since the 1830s settlers begin relentlessly pursue this animal on charges of killing their sheep.

Maybe it survived on the Australian mainland
There are some observations of Tasmanian tiger on the Australian mainland. Be assumed that if he did survive it is very rare and that it is in need of urgent protection. The footprints were found that might belong to this animal and it also was a statement by which many have heard the sounds of what were advertised Tasmanian tigers. There was a statement from people who claimed to have seen this animal in nature. However, in spite of research, found no clear evidence of the existence of these animals.

Tasmanian tiger images

They can open jaw unusually wide

Tasmanian tigers were able to open the jaw unusually wide – to an angle of 120 degrees. This can be seen in a short black and white film from 1933 by David Fleay, which displays the last captive specimen of this kind.

Males had quivers
It was one of two known marsupials in which both sexes have a quiver. Males had quivers that they serve as a shield for the reproductive organs while running through thick vegetation.

It is a nocturnal animal
Tasmanian tiger is a nocturnal animal. It hunted mostly at night, and it is believed to have been ambush predator.

Prize of 1.000.000 dollars
There is a prize of one million dollars to anyone who proves that the Tasmanian tiger still exists, but so far no one has won money.

It could be cloned in the near future

Tasmanian tiger could be the first animal returned from the dead as the Tasmanian scientists begin the separation of its genetic code in order to cloning. Otherwise, 1986, the species was declared as extinct.

Since 1936, when the last specimen of this animal has died, there are more than 4,500 reports that the animal was seen, but the real proof is still missing.

Hundreds of white tigers in zoos
In zoos lives several hundred of white tigers, and there are many because people are trying mate white tigers to influence the genes and increase the chances of the birth of new white tigers.

Some people consider it as a new kind of tigers. Today, all white tigers are descendants of countless generations and crossing that worked on it to get a double recessive gene, a gene that gives a white color tiger fur.

They are larger and stronger than normal tigers
They are usually larger than normal tigers, grow faster and earlier reach maturity. Also are much more muscular and stronger, and lot more aggressive. Because of its color and size they are an attraction in zoos. Despite its unusual coloring, their size can be an advantage in the wild.

However, almost all white tigers have strabismus, even when it is not noticeable at first glance, and they suffer from a series of health problems, because their parents are usually realtives (often brother and sister). In addition, they live very shortly, up to 10 years, while normal tigers live up to 25 years in captivity. They also often suffer from club feet, cleft palates, spinal deformities and defective organs.

Siberian tiger can not be white
White Tiger may be only Bengal tiger or Amur tiger, while in Siberian tiger is no a gene that carries the white fur. White tigers in nature are born in one in 10,000 cases. Tigers are the largest cats and are loners who never live in groups.

All white tiger once in 100.000
Their stripes are like human fingerprints – there is no two of the same pattern anywhere in the world. Cub without stripes is born once in 100-000 cases. There is up to 10 all white tigers in the world, and most famous Fareeda, born in 2009. It is completely normal and without health problems for now.

The creation of white tiger
Reva Maharadza Martand Singh first noticed a male white tiger named Mohan during his visit to Jungle of Reva in India. After several months of hunting, he caught the first live specimen of white tiger. With the help of veterinary experts he unsuccessfully trying to match the white tiger for a female of white color. At the end, he succeeded in creating a new generation of tigers. Over time, it has spread around the world as white tiger.

Attacks on humans
One of the white tigers named Paris, the symbol of the zoo in the Czech town of Liberec, in 2012 attacked and injured three guards. It weighs 250 pounds, and attacked in the cage 18-year-old guard and two women who care about it, and then escaped from the cage. It was later killed on street by police.

In June 2015 one white tiger escaped from the zoo in Georgia and in the street killed one person. There have been many cases where the white tigers attacking people and statistically they are much more aggressive than normal tigers.
