Where seen? This small purplish sea cucumber is sometimes seen under stones, particularly on our Northern shores. Usually alone, but sometimes several are seen together under one stone.

Features: 3-8cm long. Body angular with short tube feet in rows along the length. The tube feet are used to cling to the underside of the stone as well as to hold debris all over the body. It is plain purple (some lilac, others deep purple).
