Project Description

It’s interesting to watch a giant sea cucumber (Parastichopus californicus) gather food, as its oral tentacles sweep over the substrate below.  This sea cucumber is gathering debris from the surface of a large kelp frond.  The giant sea cucumber can grow to 20 inches (50 cm) long, and has stiff conical spikes or papillae.  Its range is from central Alaska to northern Mexico, and lives on rocks and soft bottoms from the intertidal zone down to 825 feet (250 m) of depth.
