Whale shark, a great white shark of the genus Whale. Whale sharks are only 1 family, 1 genus and 1 species. The human body is huge, with a total length of 20 meters, making it the largest fish species in the world. The epidermis is scattered with light-colored black spots and wrapped with light-colored bands. The nasal cavity is located on both sides of the upper lip and occurs inside the mouth. Teeth are numerous and fine, arranged in several rows. There are 5 pairs of branchial cleft, the number of which is huge, basically reaching the back edge and abdomen edge of human body, and finally 1 pair of branchial cleft is located right in front of the tip of pectoral fin. There are two dorsal fins and no thorns. The first dorsal fin is located in front of the pectoral fin and has a gluteal fin. The caudal stalk has a lateral edge, the caudal fin is crescent-shaped, and the lower leaf is shorter than the upper leaf. For example, whale sharks have two dorsal fins of different sizes, and the pectoral fin is larger, which is located below the third pair of branchial cleft. The pectoral fin is small, the mouth is wide, and the gill rake is like a honeycomb.

Whale sharks are filter feeders, feeding on zooplankton, macroalgae, krill and small and medium-sized fish. Their teeth can't feed, in fact, their specifications are not too big. Instead, whale sharks take a sip of water, close their mouths and drain water from their gills. In the short time between the closure of lips and the opening of gill cover, zooplankton are entangled with cortical scales in gills and throat. This human organ, which is similar to the filtering device, is a unique genetic variation of the gill rake, which can block all objects over 2 to 3 mm and the liquid will be discharged.

Whale sharks gather in the rocky area off the island of Beris Cura? ao to feed on the eggs of giant Mexican snapper, which will appear between the full moon in May, June and July and the children's string moon. The main components of whale sharks are krill, crab fry, jellyfish skin, tuna, anchovies, mackerel, small bluefin tuna and big squid. Whale sharks are generally independent theme activities, and rarely get together unless they are looking for food in areas with rich ingredients. The theme activities of male whale sharks are higher than those of female insects, because female whale sharks prefer to take place at special addresses.

Although whale sharks are huge, they are not easy to cause serious harm to people. They are often used by biologists for cultural education and social development. Don't great white sharks know all about it? Eating human flesh? . In fact, whale sharks have a lot of personality and play with deep divers. There are unconfirmed reports that whale sharks will stay still, turn the human body and let deep divers remove parasites from the abdominal cavity. Deep diving workers can swim with this huge fish without being affected by all the risks, except being accidentally hit by the huge tail fin of a whale shark in a meeting.
