As in C. pennigonu. advanced larvae had a well-developed preoral lobe from which the central bra- chium emerged as a bulge-like protrusion (Fig. 4B. C). They swam anterior end up with their ciliary cover (Fig. 4F). Advanced larvae (10 days) had a well-developed brachiolar complex which was used for benthic attachment. They exhibited typical settlement behavior while exploring the.
