The sea cucumber "Sea Apple" is an animal. Sea apple refers to a round and large sea cucumber with a gentle temperament. It is a kind of sea cucumber. It is about 10 cm long. The color of its body is the most colorful among all sea cucumbers. It is yellow, pink or orange. It can grow up to 10 cm. There are many tentacles around the mouth. There are obvious tube feet on the body surface, which are yellow, pink or orange. Sea apples feed by extending these tentacles to send the captured food into their mouths. The tube feet are tools for movement. Unlike other sea cucumbers, they will not spit out their internal organs when encountering enemies. They usually do not approach fish because fish will peck at their breathing tentacles.
Sea apples are carnivorous and mainly feed on plankton. They like to eat very small live or frozen baits, such as brine shrimp nauplii and rotifers. They have limited digestive capacity and limited food intake.
