Extract

Poly dor a ciliata (Johnston) is a polychaete which lives in a U-shaped tube and is found in a wide variety of substrata, ranging from soft clays or muds to hard calcareous materials. Cliona celata Grant is a siliceous sponge which inhabits tunnels and galleries it has etched out in limestone, coral or molluscan shells. The effects of these two species of boring organisms on their hosts have been studied mainly for commercially important molluscs. Hannerz (1956) is the only record of P. ciliata infectingPatella vulgata L, and there is no previous record of anyCliona spp., infections.
