Because starfish cannot move as fast and flexibly as sharks, they mainly prey on slow-moving marine animals, such as shellfish, sea urchins, crabs and anemones. It often adopts a slow and hesitant strategy to catch its prey, slowly approaching it with a pin on its wrist and wrapping its whole body. It dissolves the stomach pouch from the mouth, dissolves the prey by digestive enzymes and absorbs it into the body. Tentacles are the teeth of starfish that eat. They can put tentacles on their prey to prevent it from escaping.

They can also open their shells with tentacles and stick out their stomachs in the chassis to digest their prey. Mild animals are herbivores, while fierce animals are carnivores. Perhaps these quiet, almost motionless starfish are more suitable for eating algae or plankton. But the opposite is true. Starfish are not only carnivores, but also fierce carnivores. Of course, they don't attack their prey as quickly as cheetahs or sharks, but they can slowly approach and give a close hug with suction cups. Starfish have no eyes and rely on various chemoreceptors to find food.

When they slowly approach the prey and catch it quickly with the needle on their wrist, they will wrap their whole bodies around the prey and then spit their stomachs out of their mouths. Digestive enzymes in the stomach will be quickly released into the prey, and then the prey will be dissolved and ingested. Starfish are carnivores, mainly preying on slow-moving marine life such as shellfish, sea urchins, crabs and anemones. Starfish is a kind of echinoderms, which is divided into two families: petrels and seagulls. They are mainly distributed in shallow seabed sand or coral reefs around the world.
