Today We Will Talk about top 10 biggest sharks in the world

  

The human fascination with sharks stems from many of their characteristics. First and foremost, large, carnivorous sharks have been known to kill and eat people, which upends the usual situation of humans killing and eating fish. Another fascinating thing about these fish is that their skeletons are not made of bone, like those of other fish, but of cartilage. Since cartilage is lighter than bone, sharks tend to weigh less than a similar-sized animal with a bony skeleton.

Number 1: Longfin Mako

This creature, with disproportionately long pectoral fins, can grow to about 14 feet long. Its long fins make it a less agile swimmer than its relative, the shortfin mako shark. It eats fish, squid, octopus, and cuttlefish and might be able to raise its body temperature. Longfin mako babies hatch from eggs while they’re still inside their mother and she lets them eat unfertilized eggs while they’re still in the womb. Though longfin makos aren’t good eating and are not sought by commercial fishermen, they are still endangered. They’re found around the world in temperate and tropical seas.

Number 2: Bluntnose Sixgill shark

This shark, which is also found around the world in tropical and temperate seas, grows on average 15.8 feet long but has been known to grow as long as 20 feet. Also called the cow shark, it is found deep in the ocean and eats whatever it can tackle with its protruding jaws, including giant octopuses. As a Hexanchiform shark, it is a rather primitive animal, with a blunt head, small eyes that lack a protective nictitating membrane, and a single dorsal fin. The cow shark is not dangerous to humans unless it’s threatened, and its conservation status is near threatened.

 

Number 3: Thresher shark

One of the biggest sharks in the world, the thresher shark can grow to around 18.8 feet in length, and much of that length is taken up by its tail, which gives the animal its name and is used to stun its prey. There are three species, and the conservation status of all of them is vulnerable. Still, people hunt them for sport, shark fin soup, their meat, and for the oil found in their livers. Leather is even made out of their skin. Thresher sharks are mainly found in the open ocean, even though now and then one ventures close to the shore, especially if the shore is over a continental shelf. This means the shelves of the North Pacific around Asia and the North American continental shelves.

Number 4: Great Hammerhead

The great hammerhead shark is the biggest of the hammerheads and is critically endangered. Found in tropical and temperate waters worldwide, it is most likely found near the coast on continental shelves. It’s not only bigger than other hammerheads, but its hammer differs from theirs because it is almost straight across, and the first fin on its back or dorsal fin is tall and curved. Scientists believe that the fish developed its hammer, or cephalofoil to stun stingrays, which is its favorite meal. The great hammerhead’s size, as much as 20 feet, makes it intimidating, but it rarely attacks humans. Unfortunately, the reverse isn’t true because its long fins are prized for shark fin soup. Great hammerhead sharks are gravid for about 11 months, then they can give birth to as many as 55 pups. The edges of their hammers are rounder than those of the adults. If they survive to adulthood, great hammerheads can live as long as 50 years.

Number 5: Great White shark

While it's not the largest shark in the world, this huge carnivore, which typically grows to 20 feet in length and weighs two and a half tons, has a fearsome reputation. The reputation is deserved, for if someone is going to be attacked by a shark, it will most likely be a great white. Its conservation status is vulnerable, and it is protected in many areas. The animal is rarely kept in aquaria because it is a migratory fish that’s used to swimming thousands of miles. It also has a diet that most aquaria can’t provide on a regular basis. This includes pinnipeds, porpoises, dolphins, sea turtles, seabirds, tuna, and other sharks. The great white also has no problem taking chunks out of larger whales. The fish is found in waters all over the world save at the Poles, with concentrations around Japan, Oceania, Chile, the northeastern United States, and California, and the Mediterranean Sea. Groups seem to prefer to meet in the North Atlantic because of the eddies of warm water found there.

Number 6: Greenland shark

This 24-foot-long fish is one of the longest-lived creatures on Earth. Biologists believe it can live as long as 500 years. It doesn’t even start to reproduce until it’s between 100 and 150 years old. Because it lives so long and reproduces so slowly, efforts are being made to protect this animal, whose conservation status is vulnerable. The Greenland shark eats fish and squid found in the cold waters of the North Atlantic and the Arctic. The fish actually comes upon its prey while the prey is asleep and simply sucks it whole into its mouth. It has also been found with the remains of mammals in its stomach, but scientists believe this is from scavenging. Because it has a lot of trimethylamine N-oxide, the flesh of the Greenland shark is poisonous to humans.

Number 7: Tiger shark

The tiger shark, which can grow to 24.6 feet long, gets its name from the stripes found on its body and probably not for its ferocity. Still, only the great white has killed more humans. But is it the largest shark? Not quite. The tiger shark is famous for eating anything it can get its impressive jaws around. It matters not if the object is edible. Edible prey include seals, squid, sea turtles, dolphins, fish, jellyfish, crustaceans, other sharks, and injured whales as large as humpbacks. It is found most often near the coast in warmer waters, and it prefers to stay close to the equator, though it’s been found as far north as Japan.

Number 8: Megamouth

The three biggest sharks in the world are plankton feeders and completely harmless to human beings. The “smallest” of these sharks is the megamouth at 25 feet in length. This fish lives in deep waters and is elusive, with a huge head, a flabby body, a thresher-like tail, and prominent lips. It’s been seen off Japan, Hawaii, and California and can dive to a depth of 3280 feet. Though its mouth is huge, its teeth are small and useless. It keeps its mouth open as it swims to pull in plankton and other small prey such as jellyfish.

Number 9: Basking Shark

At nearly 50 feet long, the basking shark comes in second as the largest shark in the world. It is found all over the world in temperate water and moves slowly, its mouth gaping to take in plankton. It gets its name because it’s often found feeding at the water’s surface, appearing to bask in the sunlight. It has hundreds of teeth, but they are small, curved, and don’t do much. The fish depends on its gill rakers to catch the plankton as it’s pulled into the mouth along with seawater. Unsurprisingly, gill rakers get worn out and are replaced and regrown continuously. This animal has been overfished for its meat, its fins, its liver oil, and for animal food. Its conservation status is endangered. Basking sharks swim thousands of miles in the summer and winter in search of rich feeding grounds.

Number 10: Whale Shark

What is the biggest shark in the world? The whale shark is not only the largest shark in the world at about 55.7 feet in length, but it is the biggest fish in the world. It is considered a carpet shark because of the beautiful pattern on its hide, which is dark gray with white stripes and what looks like polka dots. These animals also have two dorsal fins and five-gill openings. They usually have small mouths. This doesn’t quite apply to the whale shark, though its mouth is smaller than that of the basking shark or megamouth. The whale shark simply opens its mouth and swims forward, which allows food and seawater to enter its mouth, or it sucks the prey in. This includes not only plankton but fish eggs, small fish, small squid, and krill. The fish has also been seen to cough to clear its throat of debris. The whale shark has dermal denticles not only on its body but on its eyes. Like those on the body, they are there for protection. The animal can also retract its eyes completely into its body. It is found in warmer waters in the open ocean and near the coast and is endangered.
