The pinnotherid crab Pinnixa chaetopterana (Stimpson) is commonly found inhabiting the tubes of the polychaete Chaetopterus variopedatus (Renier), but the interaction between these crabs and their hosts is quite different in nature from that which occurs between bivalves and their pinnotherid species.

Chaetopterus variopedatus (Fig. 4) is widely distributed in the world, although a recent molecular phylogenetic analysis sug-gested its status as a species complex (20). It is a filter feeder, living in a U-shaped tube in the mud of marine shallow water, both ends of which stick out of the seafloor.

When Arbacia, Asterias and Chætopterus eggs are inseminated in CO2-free sea water of varying H-ion concentration, a block to fertilization appears at a H-ion concentration which is constant, and apparently characteristic for each species.
