Foraging behavior is an instinctive behavior of animals. When animals are hungry, they naturally look for food and water to meet their physiological needs, so as to survive. Animals that lose their ability to eat will soon die.

Foraging behavior includes several stages, such as searching, chasing and catching, processing and feeding. The ultimate goal of biological foraging behavior is to get the most energy in a certain period of time, and in the process of foraging, biological individuals are constrained by their own conditions and environmental restrictions.

The foraging behavior mechanism, foraging activity time and distribution strategy of animals are of great significance to the survival and reproduction of animals. By observing the characteristics of individual foraging behavior and understanding the influence of foraging behavior on foraging efficiency, it is helpful for people to explore efficient search strategies, develop new swarm intelligence algorithms and realize coordinated control of swarm robots, and provide scientific basis for the optimization of complex systems.

Animals have their own unique ways of hunting. Hydra preys by stretching tentacles, releasing stingrays and venom to anesthetize prey, and then sending prey to the population with tentacles. Small carnivores look for food by "waiting" or ambush.

Some large carnivores hunt by chasing after them, winning with speed and endurance. Other animals use special structures to trap food. For example, turtles use their tongues as bait to lure small fish; Deep sea? ? ? ? Use mouth lights to automatically lure small animals into the population.
