Sardines are a kind of fish that live in the ocean. They mainly eat the plankton around them. Specifically, sardines eat different foods. For example, the plankton eaten by young fish is different from that eaten by adult fish. When they are young, sardines can eat plankton larvae, such as crustaceans, and they can also eat dinoflagellates and diatoms. When they reach the adult stage, they become larger, and they can eat some larger plankton, specifically a variety of species, such as amphipods, copepods and so on.
In addition, there are many different kinds of sardines, and the food they eat is also different. For example, there is a species called "golden sardine", which can eat diatoms, mysids, short-tailed plankton and so on when they grow up. In addition, in different sea areas and different seasons, sardines eat different foods, but in general, plankton is the main food of sardines.
a single sardine is relatively small, and their ability to prey will not be very strong. However, sardines generally gather together, and a group of sardines will enhance their predatory ability, and their predatory efficiency is relatively high. Schools of sardines can catch larger creatures. When hunting, sardines will act collectively, forming a whirlpool together, trapping or confusing prey, and then eating prey.
