The whale shark (Rhincodon typus) is a slow-moving, filter-feeding flooring shark and the largest noted extant fish species. The largest confirmed individual had a duration of 12. 65 m (41. 5 ft) and a weight of about 21. your five t (47, 000 lb).[8] The whale shark holds many records for size in the pet kingdom, most notably being definitely 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 marine environments of the tropical oceans and it is rarely found in the water beneath 21 °C (70 °F).[2] Modeling suggests a lifespan of about seventy years, but measurements own 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 plus the basking shark. They supply 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 Clean, South Africa. Andrew Smith, a military doctor associated with British troops stationed in Plaid Town, described it the next year.[10] The name "whale shark" identifies the fish's size, becoming as large as some types of whales,[11] as well as its being a filter feeder like baleen whales.
Whale sharks have a mouth that can be 1 . 5 m (4. 9 ft) extensive, containing 300 to 350 rows of tiny teeth and 10 filter pads which usually it uses to filter supply.[12] Unlike some other sharks, whale sharks' lips are located at the front of the mind rather than on the underside from the head.[13] Whale sharks have five large pairs of gills. Your head is wide and even with two small sight at the front. Whale sharks happen to be grey with a white stomach. Their skin is designated with pale yellow locations and stripes which are one of a kind to each individual. The whale shark has three visible ridges along its factors. Its skin can be about 10 cm (3. on the lookout for in) thick. The shark has a pair of dorsal fins and pectoral fins. Juveniles' tails have a larger high fin than the lower b, while the adult tail turns into semilunate. The whale shark's spiracles are just behind it is eyes.
The whale shark is the largest non-cetacean canine in the world. The average size of adult whale sharks is believed at 9. 8 meters (32 ft) and 9 t (20, 000 lb).[8] Several individuals over 18 m (59 ft) in length have been reported.[14] The largest confirmed specimen was caught upon 11 November 1949, near Espumarajo Island, in Karachi, Pakistan. It was 12. 65 meters (41. 5 ft) much time, weighed about 21. a few 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 no scientific records support their very own existence. In 1868, the Irish natural scientist Edward Perceval Wright obtained many small whale shark individuals in the Seychelles, but advertised to have observed specimens above 15 m (49 ft), and tells of shark specimens surpassing 21 m (69 ft).
In a 1925 publication, Hugh Meters. Smith described a huge animal caught in a bamboo fish trap in Thailand in 1919. The shark was too heavy to pull ashore, although Smith estimated the shark was at least 17 m (56 ft) long, and weighed around 37 capital t. These measurements have been exaggerated to 43 t (95, 000 lb) and a lot more precise 17. 98 meters (59. 0 ft) lately. A shark caught in 1994 off Tainan Local, 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 90 tonnes (220, 000 lb). In 1934, a vessel named the Maurguani discovered 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. 6 m (15 ft) on a single side and 12. a couple of m (40 ft) one the other side of the coin.[16] No dependable documentation exists for these promises and they remain "fish stories".
