BEACHCOMBING ON THE DELPHI BEACH, ABACO (PT 2): BIVALVES


This is Part 2 of the ‘Delphi Beachcombing’ feature. The first dealt mainly with gastropods, and now I have got round to some bivalves. All the shells illustrated come from somewhere within half a mile of the Delphi Club beach steps, except for the sunrise tellin. We gave ours to our granddaughter (5) [she likes pink, but also mud] and it has… somehow come apart. 

EGG COCKLES Unlike the vast majority of cockle types which have the familiar radial ribs, egg cockles are smooth and non-ribbed. They are apparently able to jump by flexing what passes for their leg – a feat I would enjoy seeing…

GAUDY ASAPHIS Asaphis Deflorata (formerly ID’d as COQUINA Donax)

TIGER LUCINE Codakia orbicularis (formerly ID’d as ELEGANT DOSINIA Dosinia Elegans)

SCALLOP / PECTEN This is not a ravenelli, as previously suggested by me –  they are deep water molluscs.  It’s hard to be sure exactly what species it is, in such a bleached state.The tiny shell half is surely the basis for the symbol of a petro-chemical giant that I decline to identify further. I thought this one was broken but a check shows that the asymmetry of the hinge is very common. Encrustation by worms, as here, is often found as well, but I wisely draw no parallel with the litigious petrochemical industry…

SUNRISE TELLIN (Tellina Radiata) Tellins are a genus with masses of variants worldwide. This species is common in the Caribbean. It is a really pretty shell, glossy with pink radials. They grow up to 7cms. As hinted above, if you find a complete one, the hinge is delicate. The most interesting fact I have discovered is that “in most countries it is illegal to bring back these shells from holidays” Whoops!
