White shark also known by other names such as white needlepoint, white death, White shark is a large shark in the order of sharks found in coastal waters throughout all oceans. The great white shark is known for its size, which can grow up to 6,4 m in length although there are reports stating it is 8 m long and weighs 3.324 kg. This species is sexually mature at about 15 years of age and was previously thought to have a life cycle of more than 30 years. The real life cycle of White shark much longer, now estimated at 70 years or more, making it one of the longest living cartilaginous fishes.
White shark reach a speed of more than 56 km/h. Great white sharks have no natural enemies other than killer whales. It is the largest carnivorous fish in existence. It hunts many species of marine mammals, as well as fish and seabirds. It is the only surviving species of the genus Carcharodon, and ranks first among sharks that attack humans.
White-eyed bull shark
White-eyed bull shark Also known as the Zambezi shark in Africa and the Nicaraguan shark in Nicaragua is a widespread, worldwide species of shark that lives in warm, shallow waters along coasts and rivers. White-eyed bull shark They are known for their aggression, prefer shallow water and are common in brackish or freshwater areas including estuaries and rivers. They can live in both seawater and fresh water and can live in rivers deep inland. They have been found in Indiana, USA in the Ohio River. They are probably the same species of shark that have attacked humans in attacks near beaches, including in cases believed to have been caused by other shark species.
White-eyed bull shark It is not a true freshwater fish, although it can live in fresh water unlike the river sharks of the genus Glyphis. A white-eyed bull shark’s diet consists mainly of bony fishes and sharks, including other white-eyed buffalo sharks, but may also include turtles, birds, dolphins, and mammals. terrestrial mammals, crustaceans, echinoderms and stingrays. They hunt in murky waters because it is more difficult for prey to detect it.
This shark is named after its distinctive head. Hammerhead sharks have two eyes placed on either side of the “cephalofoil” – the hammer, allowing them to see both above and below at the same time. Hammerhead sharks have the ability to rotate very flexibly at high speeds. This fish usually swims in schools during the day, and has a tight power order in the group.
The recognizable feature of these fishes is the distinctive cartilaginous structure at the tip that is flattened and extended to the sides to form the shape of a “hammer”. Hammerhead sharks There are 2 eyes on either side of the “hammer head” that help them see above and below at the same time, not only that, but they have the ability to rotate very flexibly at high speed. During the day, hammer sharks move in groups, up to 100 individuals, at night they are individual predators. Due to moving in groups, the hammerhead shark’s hunting and attacking enemies are very scary.
Wide mouth shark
Wide mouth shark is an extremely rare species of shark that lives in the deep sea. The widemouth shark’s shape is very distinctive, but other than that, relatively little is known about the animal. It has a dark brown dorsal, white ventral side and an asymmetrical tail with a large upper lobe resembling the tail of a shark. The inner part of the gills has horizontal lines created by finger-shaped gill combs that help filter food in the water. Wide mouth shark has a poor swimming ability and has a soft, flabby body and no tail.
Like a whale or a shark basking in the sun, wide mouth shark feed on floating organisms by filtering them in comb teeth in their mouths they always swim with their mouth wide open to catch food. The distinguishing feature of this species is its very large head and mouth and rubbery lips. From one widemouth shark to another, the widemouth sharks are so rare and exotic that they have a family of their own in the taxonomic Megachasmidae. These flabby fish are slow swimmers with soft fins and asymmetrical tails.
What we do know is that they are filter feeders and can grow up to 18 feet long. In addition, the wide mouth is surrounded by light-emitting organs (photophores), thought to be used to attract plankton. Wide mouth shark They live deep down during the day and come up close to the surface at night, following their food source. Incredibly, there have only been 54 recorded sightings of this fish since its first discovery off the coast of Hawaii in 1976, when one became entangled in the anchor of a US Navy ship. They are found in the Pacific, Atlantic and Indian Oceans.
Shortfin Mako shark
Shortfin Mako shark is the fastest shark in the water, it has the same speed as the cheetah on land. Their characteristic is that they have 2 short fins compared to other sharks, the back is blue and the belly is white. Mako sharks are found throughout tropical and temperate seas around the world, they are very deep in the sea. Their prey is a very fast swimmer tuna. Shortfin Mako shark there are tons of people, the people they attack are usually the scuba divers and the people who feed it.
Shortfin mako shark Adults are 2,75 – 4 m long and can weigh up to 800 kg, with a bluish back and white belly. Although both sexes develop at the same rate, female (shortfin mako) sharks are thought to have a longer lifespan and they are also larger and heavier than male sharks. Shortfin mako sharks are famous for their speed and ability to jump out of the water. They have a better hydrodynamic shape than other sharks, and this, along with the rhythmic, lithe muscles typical of great whites, is the reason for their speed and agility. mako sharks in general.
Velocity of shortfin mako shark can reach 50 km/h (31 mph) and there are some reports of individuals reaching speeds of 74 km/h. They can jump up to 6 meters out of the water. Shortfin mako sharks are oviparous, meaning that the young develop with an ovum contained in a sac that remains in the uterus until birth. The pregnancy cycle of a mako shark is about 15-18 months. It has also been found that mako shark fetuses in the mother’s body consume each other for nutrients. This is called cannibalism in utero.
Ccookiecutter shark also known as the cigar shark, is a small species of squaliform shark in the family Dalatiidae. This shark occurs in warm, oceanic waters worldwide, especially near islands, and has been recorded as deep as 3,7 km (2,3 mi). It moves vertically up to 3 km per day, approaching the surface at dusk and descending with dawn. Only 42 – 56 cm long, cookiecutter shark has an elongated cylindrical body with a short, blunt snout, large eyes, two small spineless dorsal fins, and a large caudal fin. It is dark brown, with glowing photophores covering its underside except for a dark “collar” around the throat and gill slit.
The bright sharks aren’t as long as their brethren, but what they lack in size makes up for in disgust. The cigar-shaped shark loiters in the water, waiting for larger prey to appear. Their bodies are luminescent, except for a dark neckline behind the head, and this dark part is thought to be the shadow of a small fish, acting as bait. Reality Cookiecutter shark feed on medium- and large-sized organisms that share a habitat in the tropics. Whales, dolphins, sharks, seals and bony fish have been found to have been injured by them. This terrifying little beast has also been known to bite submarines, underwater cables, and even humans.
Crested shark is an uncommon species of bullhead shark in the family Heterodontidae, distributed off eastern Australia from the coast to a depth of 93 m. This shark can be distinguished from other members of its family by the large size of the ridges on its eyes and the color pattern. It usually reaches 1,2 m in length. Nocturnal and bottom-dwelling, this fish prefers rocky reefs and areas of vegetation, where it hunts sea urchins and other small creatures.
Crested shark are egg-laying species, the female lays egg sacs attached to seaweed or sponges with long tassels. Sexual maturity is slow, with a female in captivity not laying eggs until almost 12 years of age. The International Union for Conservation of Nature (IUCN) has assessed this harmless shark as of Least Concern, with no economic benefit and minimal mortality from recreational fishing. and shark nets. Despite living far from shore, this shark will attack just about anything it comes across, especially shipwreck victims or divers at sea.
Long-nosed sword shark
Long-nosed sword shark One of six species of sword shark, it can grow up to four and a half feet long. They are characterized by a long, serrated nose with rows of sharp teeth that account for a third of their weight. When the long-nosed sword shark finds its prey, it flips its nose around, injuring, and even impaling its unfortunate victim’s torso. The shark shakes its head vigorously until the prey falls out of its multi-toothed nose and then it sucks the prey into its mouth and chews it up with its sharp teeth.
Long-nosed sword shark also has long antennae that grow down the sides of the nose – rather like a beard – and use it to find food. The antennae are completely movable, and they sense vibrations and bioelectricity, similar to how hammer sharks find their favorite stingray snack. What’s even more interesting is that this antennae is very sensitive to touch and taste – which makes them perfect for sensing prey hiding in the sand.
Tiger shark also known as flower shark, leopard shark is the only shark in the genus mink shark, the white-eyed shark family. Great tiger sharks have an average size of 3,25m and weigh from 385 to 909 kg. This fish lives in tropical and temperate oceans around the world, especially around the central Pacific islands. They are carnivorous sharks in the ocean and eat almost anything, even metal. This makes them a threat to humans, they attack humans and among the dense population of many tiger sharks have human carcasses. The tiger shark is blamed for many human deaths because it occasionally swims close to shore in pursuit of turtles.
Tiger shark is one of the largest sharks on the planet. Tiger shark Aquatic tigers share some similarities with land-dwelling tigers, both of which are excellent hunters. They can hunt at high speed. When it comes to their ability to smell and see to hunt, tiger sharks are on the top of the list. It is said that they can smell far behind their prey. This can be called the sixth sense of a tiger shark. This makes it easier and faster to hunt than other animals.
