Photographed at 20 m depth. To feed, this sea cucumber sequentially places one arm with it's sticky tentacles and entrapped planktonic material within the mouth, licks off the food, extends the arm, and then repeats the process.

Males and females spawn synchronously in the Spring as they extend their bodies from the rocks. The eggs are toxic to fish.
