Mariene mollusken uit het oostelijk deel van de Middellandse Zee. 10. Voorwerpen die door Cucurbitula cymbium gebruikt worden als substraat

The Lessepsian migrant Cucurbitula cymbium is commonly encountered on all kinds of firm objects dredged or trawled from depths ranging between 9 and 91 m. The flask-like ‘cocoon’ in which this bivalve lives is most often encountered adhering to the inside of empty bivalves (52 species); it is also often found in the aperture of dead gastropods (12 species) and even on an old landsnail, tuskshells, a sharktooth, corals, bones and pebbles. In the shell of Glycymeris bimaculata a boring specimen of Cucurbitula was encountered lacking the characteristic flask-like ‘cocoon’. Of particular interest was the find of a single specimen in a damaged valve of Lucinoma borealis, a species not reported before from the Mediterranean Sea off Israel.
