a whale shark is a shark. It itself is a Chondrichthyes shark whale shark family of animals, is the world's largest shark, but also the largest fish. The reason why there is a whale in the name is that its body is as big as a whale, up to 10 meters in length, and the largest can even reach about 20 meters. However, although it is a shark, it is indeed a very docile animal and rarely attacks humans.
Although whale sharks are huge, they mainly use inhalation filter feeding to eat, so their food is krill and plankton. Although this method of feeding is relatively low, it allows them to avoid competing with other giant marine organisms for food. Moreover, it also allows them to better adapt to the environment and avoid the extinction of species due to the reduction of food.
Whale sharks need to suck water into their mouths and then expel it with their gills. At the moment of closing the mouth and opening the gill cover, plankton are trapped in the cortical scales of the gills and throat, which can prevent 2-3 mm of objects from passing through, and only water can be discharged. After the water is discharged, the remaining objects will be swallowed by it.
Whale sharks prefer to live alone and rarely gather together except in places where food is abundant. In addition, males generally have a larger range than females, and females prefer to be in preferred places. They swim slowly and often bask on the surface of the water.
