Project Description

This pale sea cucumber feeding (Cucumaria pallida) was interesting to watch as food particles were gathered from the surrounding water.  The tentacles of this suspension feeder are first extended outward into the ocean current, and slowly one tentacle is drawn towards the mouth and placed inside so captured particles can be swept off.  This cleaned tentacle is then released back into the current and the process starts again with another tentacle at a slow fluid pace.  The pale sea cucumber can reach 10 inches (25 cm) in length, with a range from southern Alaska to southern California.
