Starfish are mainly slow moving animals that eat shellfish, sea urchins, crabs and sea anemones. Starfish are carnivorous animals, but their activities are not flexible and fast enough, so they can only prey on some slow-moving shellfish, sea anemones and other marine animals. Starfish's predation strategy generally takes a slow detour, slowly approach the prey, suck the prey with tube feet, wrap the whole body around the prey, spit out the stomach bag, and the digestive enzymes in the stomach will dissolve the prey. 1、 What does starfish eat? Starfish are carnivorous animals living in the ocean. They can hunt some invertebrates for food. Its main feed is some slow moving animals such as shellfish, crustaceans or fish in the ocean. Starfish mainly live on sand or reefs in the shallow seabed of the sea. When starfish prey, they always slowly pick up their prey, detour and return quietly, bind the prey tightly with the whole body, and then swallow it with a stomach bag. Different species of starfish also eat different feeds. Some are carnivorous and some are omnivorous. Omnivorous starfish mainly eat dry seaweed, clam meat or raw meat slices. When feeding, just put the food under or near the starfish's body. 2、 How do starfish prey? 1. Most starfish have long, bendable wrists, and the tube feet on the wrists have a lot of suction cups. When eating crustaceans, the suction cup at the end of their tube foot can open the shell mouth of bivalve prey. The starfish spits out the vent, and the stomach immediately inserts into the soft part of the shell mouth, and secretes a large amount of digestive enzymes. Slowly, the adductor muscle and internal organs are digested. Then the starfish can surround and swallow their prey with their stomach.
2. Most species of starfish living in the deep sea feed on cilia. They will filter the sediment organic matter falling into the starfish's body into the step belt groove to form a food cord, and finally eat it in the inlet. This kind of starfish species include Maple starfish, chicken claw starfish and so on. （HaiXingChiShenMeSiLiao）
