Green Bomber (Swima bombiviridis)

Local distribution of the polychaetous worm Clymenella torquata. This is likewise determined by the character of the bottom, but is almost the converse of that of Nereis pelagica, the present species being in a large degree restricted to a muddy habitat.

Parasite on the Skate (Hirudo muricata).
