features
The white-tipped sea cucumber has a velvety black skin with numerous bright white papillae . Your body size is up to 25 cm, the body cross-section is almost cylindrical . On the belly side it has suction feet in three rows. The tentacles of the white-tipped sea cucumber end in star-shaped disks, Cuvier's tubes are missing.
The white-tipped sea cucumber feeds on organic material ( detritus ), which is shoveled into the mouth with the star-shaped tentacle ends. However, soil material is swallowed indiscriminately and only selected in the digestive tract. Indigestible components are excreted through the sewer opening in the form of small "sand sausages".
