The body is cylindrical, 10-20 cm long, and the extra large one can reach 30 cm. It is dark and has many thorns. The tentacle is wheel shaped, with 17~30 tentacles, generally 20 tentacles. The touch and hand jar bags are developed. Sea cucumbers breed earlier on the earth than primitive fish. They began to exist in the Precambrian period more than 600 million years ago. They are early living biological species and are known as living marine fossils. After several great earth disasters, they have survived and witnessed the changes of the earth several times. The mouth is in the front, mostly inclined to the ventral surface. The anus is at the back end, mostly at the back. There are usually wart feet on the back and tube feet on the ventral surface. Endoskeletons degenerate into tiny pieces of bone. Many species have five tube feet from mouth to anus. The anal orifice is also responsible for breathing and discharging waste. There are 10 or more retractable tentacles around the mouth for hunting or digging. Many species can release internal organs from the anus, and then regenerate new ones, possibly to avoid enemies. The cloaca is often symbiotic with Carapus. There are many toxins that can release lethal toxins to small animals, but they are not life-threatening to people.
