The entire process of development from eggs to juveniles in the brittle star, Ophioplocus japonicus, is described with special attention to external morphology. The breeding of this brittle star in Toyama Bay, Sea of Japan, occurs in August. The eggs are spherical, orange, and 300 μm in average diameter. Cleavage is total and radial. Gastrulation takes place by invagination. Larvae possessing tube-foot buds and ophiuroid rudiments on the posterior part of their bodies, develop into the vitellaria stage. Vitellariae of the present species have transverse ciliary bands, but no larval skeletons. Six days after fertilization at 25℃, metamorphosis is completed and the resulting juvenile is pentagonal in outline and about 400 μm in diameter. The present study shows that ciliary bands are formed in an earlier larval stage than was reported previously.
