Whale sharks are whales or sharks. Why do whale sharks eat plankton

Sharks are not whales, but sharks. It is the largest fish in the world, with a body length of about 10 meters and a maximum length of 20 meters. It is because it has the same body shape as a whale that it has this name. Its feeding method is inhalation filter feeding. After sucking in the seawater full of plankton, it discharges the water and swallows the left things. This way of feeding allows them to avoid competing with other marine organisms for food, so as to survive better. 1、 Whale shark is a whale or a shark. Whale shark is a shark. It is the largest shark and the largest fish in the world. The reason why the name has the word whale is that it is as big as a whale, with a length of up to 10 meters, 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. 2、 Why do whale sharks eat plankton? Although whale sharks are huge, they mainly eat by suction filtration, so their food is krill and plankton. Although this feeding method is relatively low-end, it allows them to avoid competing for food with other giant marine creatures. Moreover, it also allows them to better adapt to the environment and avoid species extinction due to the reduction of food. 3、 How do whale sharks prey? When whale sharks prey, they need to suck water into their mouth and then discharge the water with their gills. At the moment of closing the mouth and opening the gill cover, plankton is trapped in the cortical scale process of the gill and throat, where 2-3mm objects can be prevented from passing through, and only water can be discharged. After the water is drained, the remaining objects will be swallowed by it. 4、 Are whale sharks solitary? Whale sharks prefer to live alone and rarely gather together unless they are in places with sufficient food. In addition, males generally have a larger range of activities than females, and females prefer to appear in preferred places. They swim very slowly and often bask in the sun on the water. （JingShaShiJingYuHaiShiShaYu，JingShaWeiShenMeChiFuYouShengWu）
