摘要

The process of resorption of spermatozoa is described in the testes of the starfish Asterina pectinifera. It is shown that the mode of resorption of the male gametes in this species is different from that in the starfish Asterias vulgaris (see Walker), A. amurensis, and Aphelasterias japonica (see Kas'yanov etal.). In these species the resorption of nonreleased spermatozoa is performed by auxiliary cells transformed into motile phagocytes. In A. pectinifera this function is performed by coelomocytes migrating into the gonad. The obtained data allow us to reach a conclusion about the presence of different mechanisms of the resorption of nonreleased male gametes in the gonads of sea stars.
