Whale Sharks

The whale shark or whale shark (Rhincodon typus) is a special member of the subclass Elasmobranchii (sharks, rays) of the class Chondrichthyes. This fish holds many size records in the animal kingdom, most notably the title of largest non-mammal vertebrate in existence. It is also the only member of the genus Rhincodon and the last surviving member of the family Rhincodontidae. This species can weigh up to 21.5 tons and grow up to 41.5 feet long. The mouth of a whale shark is about 1.5 m wide. Their jaws have more than 300 teeth, but act as a food filter, they do not use these teeth to eat. In addition to being the largest fish, it is also the largest living non-mammalian vertebrate. This shark lives in tropical waters above 70 degrees F. It lives along the coast and in open water. Although it usually spends most of its life alone, there are numerous reports of up to 400 individuals congregating near multiple locations, including off the Yucatan Coast.

A decades-long survey of animals living in the oceans shows that whale sharks are the largest fish in the world. The largest whale sharks of this species are female whale sharks. The largest whale shark scientifically measured weighed 47,000 pounds. It is 41.5 feet long. It was captured near Pakistan on 11 November 1949.

Whale sharks eat a variety of foods, but they only prefer plankton. They often bang their fins on coral reefs, then open their huge mouths and suck up these plankton.

Basking shark

Basking sharks (also known as basking sharks), the second largest fish in the world after whale sharks, are occasionally spotted performing strange circular dances. It already weighs more than 4.2 tons and can reach 40.3 feet long. It is one of only three plankton-eating shark species in the world. This shark found in warm waters around the globe is so named because it appears to be dipping in the water while feeding.

These sharks are usually solitary, coming together only during mating season, although observers have never seen them mate. They have swam in circles in the past, and while that is suspected to be mating-related behavior, the exact reason for this activity has not been confirmed to date. Scientists aren't 100% sure, but they think this shark can live to be around 50 years old.

The largest basking shark ever scientifically measured weighed 8,598 pounds and was nearly 30 feet long.

Great white shark

The great white shark (scientific name: Carcharodon carcharias), also known by other names such as white needle nose, white death, white shark, is a large shark of the order Collected sharks found. in coastal regions across all oceans. Great whites, or pointer sharks, can reach 3.34 tons and can grow up to 23 feet long. These sharks can live to be 70 years old. Females usually do not give birth until they are 33 years old. These sharks can swim up to 16 miles per hour and reach depths of up to 3,300 feet. The great white shark is very aggressive and is known for more attacks on humans than any other fish. It is the only known member of the genus Carcharodon.

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.

Some think the Great White Shark off the coast of Hawaii, which researchers have named Deep Blue, is the largest ever. However, the International Game Fish Association still recognizes a great white shark measured in Australia in 1959 as the largest. Scientists have never measured Deep Blue, but the Australian animal weighed 2,663 pounds.

Leopard shark

Leopard shark, also known as flower shark, tiger shark, tiger shark scientific name Galeocerdo cuvier, is the only species of shark in the genus Galeocerdo, family Carcharhinidae.

The great leopard shark has an average size of 3.25 m and weighs between 385 and 909 kg. This fish lives in many tropical and temperate oceanic areas around the world, especially around the central Pacific islands. This fish specializes in hunting at night. They are striped like a leopard and will fade as they mature. The leopard shark is a dangerous predator that eats a variety of foods. They eat fish, seals, birds, smaller sharks, squid and sea turtles.

Sometimes people find in their digestive tracts human waste such as license plates or pieces of old tires. This species is notoriously dangerous for attacking swimmers, divers and windsurfers in Hawaii; and they are often called "the scourge of Hawaiian surfers" and "the trash can of the sea".

The leopard shark is second to the white-eyed buffalo shark in terms of the number of shark attacks on humans and is considered, along with the great white shark, the white-eyed shark, and the oceanic white-head shark as a species. the most dangerous shark species to humans. This is the fourth largest cartilaginous fish species after whale shark, basking shark, crutch fish, great white shark.

Giant stingray in the ocean

Weighing 3 tons, the Ocean Giant Stingray (Mobula birostris), also known as the Atlantic stingray, can grow up to 15 feet long. It can have a wingspan of up to 30 feet. Most of this species, which is the largest manta ray globally, lives in tropical and subtropical seas. Researchers misclassified this species until 2017.

These smooth-skinned discus fish have been found as far north as New Jersey and as far south as South Africa. If you see one near the shore, it may be rushing from place to place, but they usually swim for miles in a straight line in open water.

Giant stingrays live in warm waters in the ocean. They swim near the surface thanks to a pair of fins attached to the chest. They are pregnant for 12 months and give birth to only one cub in each litter. Contrary to rumors, giant rays do not attack divers. They can swim more than 1,100 km in 60 days. The main enemies of giant rays are large sharks and whales.

Ocean sunfish

Coming in at number six on this list is the ocean sunfish (Mola mola), also known as the mola. This fish that lives in tropical and temperate seas around the globe has a fat head and thin body.

In short, the body of the sunfish is a large head with fins. It can measure up to 3.3 meters in length and a maximum weight of 2300 kg, although it typically ranges between 247 and 2000 kg. Their skin is covered with a slime that has a sandpaper-like texture. It is quite thick and has no scales. Its color can vary in different shades such as gray, brown and silver gray. They usually have a white belly and some may have white spots, both on the lateral and dorsal fins.

If we compare it with other fish, the sunfish doesn't have many vertebrae and lacks nerves, pelvic fins, and a swim bladder. Therefore, this fish is a very rare species, morphologically different from the common species. The dorsal and anal fins are long, and the pectoral fins are adjacent to the dorsal fin. Another odd part this fish has is that instead of a caudal fin, it has a tail that serves as a rudder and extends from the posterior edge of the dorsal fin to the posterior edge of the anal fin. Its mouth is filled with small teeth that form a beak.

The sunfish is found all over the world. However, the areas where their populations are highest are in the temperate and tropical regions of the Atlantic, Pacific, Indian and Mediterranean oceans. In these places, their habitat corresponds to deep coral reefs and algal beds in the open sea.

Southern sunfish

A nearly 3 ton sunfish discovered near a Portuguese island has set a new world weight record, according to a new study. This giant sunfish, also known as the humphead sunfish (Mola alexandrini), was discovered when it washed ashore on Faial Island, in the Azores - a group of Portuguese islands in the North Atlantic Positive.

The researchers performed a dissection of the giant sunfish and detail the results in a new study, published October 11 in the Journal of Fish Biology. The giant fish is about 3.6 m high and about 3.5 m long, weighing 2,744 kg. The researchers also analyzed the contents of the sunfish's stomach and took a sample of its DNA. The previous world record belonged to a sunfish caught in Japan in 1996, weighing about 2,300 kg.

Sunfish have round bodies and often bask in sunlight at the ocean's surface, which scientists believe is their way of warming themselves after long periods of diving into cold dark waters to find food. food. They use their huge fins to move across the water when horizontal.

While many of the fish on this list are elusive, it's not uncommon to see these Osteichthyes fish lolling just below the surface throughout the oceans of the Southern Hemisphere. Scientists believe that the fish dives deep in cold water to catch prey. Meanwhile, seagulls feed on the parasites present on them.

Beluga sturgeon

The Beluga sturgeon (Huso huso), which is also known as the great sturgeon, can weigh up to 2,072 tons and grow to 24 feet long. The largest of these sturgeons is usually a humpback. They both have long dorsal fins and shorter anal fins. This species of Osteichthyes lives mainly in the Caspian basin and the Black Sea. Females are often the target of commercial anglers because of the caviar Beluga produces.

They can live up to 150 years. The population of this species is declining sharply due to overfishing or poaching, which has led many countries to implement a ban on trade in fish products. IUCN classifies Beluga sturgeon as endangered. It is a protected species listed in Annex III of the Bern Convention and trade in its products is prohibited under CITES Appendix II. The Mediterranean population is strongly protected under Annex II of this Bern convention, which prohibits any international fishing for them.

The United States Fish and Wildlife Service has banned the importation of Beluga caviar and other fish products from the Caspian Sea since October 7, 2005.

Sharptail Mola

Sharptail Mola (Masturus lanceolatus) is a species of mola found in tropical and temperate seas, rarely seen in the wild, feeding on a wide variety of species including orcas, sponges, and sea sponges. ,... Masturus lanceolatus can reach about 3.3 m in length and weigh up to 2 tons.

This Osteichthyes resembles an elliptical sunfish in many ways, but it has a tail with a sword-like protrusion in the center. It usually lives in tropical and temperate seas. Scientists don't know much about its behavior or the many locations where it might have lived. Anglers caught this fish in the Gulf of Mexico.

Hoodwinker sunfish

The Hoodwinker sunfish (Mola tecta), commonly known as the sunfish, is the 10th largest fish in the world. This member of the Osteichthyes fish has a flat elliptical shape. It can weigh up to 1.87 tons and grow up to 7.9 feet long.

Scientists working near New Zealand first reported it in 2014, but people have reported seeing it near Chile, South Africa and Australia. It is difficult for researchers to identify this fish because they often dive hundreds of meters to catch prey. They tend to live in the colder climates of the Southern Hemisphere's oceans, where people don't normally go. This tailless fish has eluded researchers for years.
