The baby at home is particularly interested in starfish. What does starfish eat?

in China, "food is the most important thing for the people". Eating is an important part of daily life for everyone in China. For those who are particular about eating, three meals a day will take up most of the day. The variety of food is wide for China people. Anyone who flies in the sky, walks on the ground and swims in the sea can turn them into tempting food on the table in minutes after a pair of industrious and intelligent hands of China people. Starfish, as a marine life from the deep sea, has been highly sought after in recent years because of its rarity and medicinal value.

Although many people know about starfish and have seen these beautiful starfish when visiting some marine life museums, many people still don't know that there are many creatures bigger than starfish in the vast ocean, and starfish is so small, so what does it usually eat? This depends on the species of starfish, but no matter which species, all starfish like to eat meat and belong to typical carnivores. And I like to eat all kinds of invertebrates, soft meat. Such as shellfish, crustaceans and polychaetes. Starfish, on the other hand, don't move as fast as other large marine animals, so they will prey on some slow-moving creatures. In addition, because of the different types of starfish, some only eat bivalves, and some are omnivorous starfish that eat more and eat everything. Generally, there are three ways to eat

1. Starfish attach themselves to the shell by using the powerful suction cups on their wrists and feet, pull the mouth of the shell open by using the strong pulling force of the suction cups, then turn out the stomach, insert it into the mouth of the shell, secrete digestive enzymes in the body, digest the adductor muscle and internal organs of the shell, and swallow the food with the stomach when the shell is dead and fully open. This kind of starfish mostly feed on bivalves, and most of them are monophagic starfish.

2. For some starfish with short wrists and no sucker on their feet, these starfish only eat very small animals, such as small crustaceans, and swallow the whole food and digest it directly in their stomachs.

3. For example, the deep-sea Acer starfish and the starfish with chicken feet, because there are cilia in the body of the starfish and in the gastric caecum, they all suck food by filtering the cilia movement.

Do you have a general understanding of starfish's diet after reading these? At present, most of the starfish on the market are dry starfish, mostly used for medicine, which has the effect of calming the nerves and has a good effect on stomach diseases.
