Whale shark first part

Whale shark: It is a slow-moving carpet shark that feeds on filtration, and is the largest living fish species currently known. The largest known individual measures about 18.8 meters (62 feet). The whale shark holds many records of size in the animal kingdom, especially as it is the largest living non-mammalian vertebrate. It is the only remaining member of the family of the whale sharks, which belongs to the class of platelets of the gills of the class of cartilaginous fishes.

Whale sharks are usually found in the open waters of tropical oceans, and are rarely found in waters below 21 ° C (70 ° F). Modeling studies suggest that a whale shark has a lifespan of about 80 years, and although measurements are difficult, estimates from field data suggest that a whale shark may live for up to 130 years. Whale sharks have extremely large mouths, and they are filter-feeding, which is a feeding method found in only two species of other sharks, which are the great-mouthed and basking sharks, as they feed almost only on plankton and small fish, and pose no danger to humans.
