| Abstract |
On large specimens of Rapana venosa (Muricidae) - collected in the Marmara Sea - covered with algae, calcareous concretions and worms, one can identify a large number of epibiontic molluscs like Mytilaster lineatus (Gmelin, 1791) (Mytilidae). Acanthochitona fascicularis (Linnaeus, 1767) and Chiton olivaceus Spengler, 1797 (Polyplacophora) are occasionally fixed inside the umbilicus of the gastropods. The thick shell, already damaged by the action of perforating sponges, is carved into galleries and cells harbouring perforating bivalve molluscs like Petricola lithophaga (Philippson, 1788) (Petricolidae) and Gastrochaena dubia (Pennant, 1777) (Gastrochaenidae). These can be considered parasitic when their number endangers the integrity of the shell by perforating it all the way through. |
