The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpeting shark and the largest noted extant fish species. The largest confirmed individual had a length of 12. 65 m (41. 5 ft) and a weight of about 21. 5 t (47, 000 lb).[8] The whale shark holds many files for size in the animal kingdom, most notably being probably the largest living nonmammalian vertebrate. It is the sole member of the genus Rhincodon and the only extant member of the family Rhincodontidae which will belongs to the subclass Elasmobranchii in the class Chondrichthyes. Before 1984 it was classified as Rhiniodon into Rhinodontidae.
The whale shark is found in open waters of the tropical oceans and is also rarely found in the water down below 21 °C (70 °F).[2] Modeling implies a lifespan of about 70 years, but measurements include proven difficult.[9] Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other fishes, the megamouth shark and the basking shark. They feed almost exclusively on plankton and small fishes, and pose no threat to humans.
The species was distinguished in April 1828 after the harpooning of a some. 6 m (15 ft) specimen in Table Gulf, South Africa. Andrew Smith, a military doctor associated with English troops stationed in Shawl Town, described it the following year.[10] The name "whale shark" refers to the fish's size, staying as large as some species of whales,[11] as well as to its being a filter feeder like baleen whales.
Whale sharks have a mouth that can be 1 . 5 meters (4. 9 ft) vast, containing 300 to 450 rows of tiny teeth and 10 filter pads which usually it uses to filter give food to.[12] Unlike a great many other sharks, whale sharks' lips are located at the front of the head rather than on the underside of the head.[13] Whale sharks have five large pairs of gills. Your head is wide and flat with two small sight at the front. Whale sharks happen to be grey with a white tummy. Their skin is runs with pale yellow locations and stripes which are exceptional to each individual. The whale shark has three visible ridges along its factors. Its skin can be up to 10 cm (3. being unfaithful in) thick. The shark has a pair of dorsal bout and pectoral fins. Juveniles' tails have a larger superior fin than the lower suite, while the adult tail becomes semilunate. The whale shark's spiracles are just behind the eyes.
The whale shark is the largest non-cetacean creature in the world. The average size of adult whale sharks is projected at 9. 8 m (32 ft) and dokuz t (20, 000 lb).[8] Several specimens over 18 m (59 ft) in length have been reported.[14] The largest confirmed specimen was caught on 11 November 1949, near Humor Island, in Karachi, Pakistan. It was 12. 65 meters (41. 5 ft) long, weighed about 21. your five t (47, 000 lb), and had a girth of seven m (23 ft).[8] Stories exist of vastly larger specimens -- quoted lengths of 18 m (59 ft) and 45. 5 t (100, 000 lb) are common in the popular literature, but not any scientific records support their existence. In 1868, the Irish natural scientist Edward cullen Perceval Wright obtained a number of small whale shark individuals in the Seychelles, but believed to have observed specimens in excess of 15 m (49 ft), and tells of shark specimens surpassing 21 m (69 ft).
Within a 1925 publication, Hugh M. Smith described a huge pet caught in a bamboo seafood trap in Thailand in 1919. The shark was too heavy to pull ashore, nonetheless Smith estimated the shark was at least 17 meters (56 ft) long, and weighed around 37 big t. These measurements have been do not forget that to 43 t (95, 000 lb) and an even more precise 17. 98 m (59. 0 ft) in recent times. A shark caught in 1994 off Tainan Region, southern Taiwan, reportedly acessed 35. 8 t (79, 000 lb).[15] There have even been unverified claims of whale sharks of up to 23 metre distances (75 ft) and 85 tonnes (220, 000 lb). In 1934, a vessel named the Maurguani stumbled on a whale shark inside the southern Pacific Ocean, rammed this, and the shark became trapped on the prow of the cruise ship, supposedly with 4. 6th m (15 ft) using one side and 12. a couple of m (40 ft) one the other side of the coin.[16] No trusted documentation exists for these claims and they remain "fish stories".
