[ref. ID; 2014]
Colonial. Inverted bell-shaped body borne upon a contractile branched stalk. Each branch develops its own very short and usually pointed independent myoneme. The severe reduction in myoneme length results in the shortening of that part of the stalk able to contract. In some species the effective length of the myoneme is extended by the presence of fibrils which run throughout the length of the stalk. Epizooic.
