Chamelea striatula

Chamelea striatula, the striped venus clam, is a marine bivalve mollusc of the family Veneridae which inhabits the northern shores of Europe.

The valves of Chamelea striatula are robust and not very convex, with a beak which is prominently bent towards the shell's anterior and sits behind a clearly delimited lunula.

Many authors quickly coined names for this overlooked species and its many slight morphological varieties, most notably Da Costa's Pectunculus striatulus (1778),[11] which today is the basis of record for Chamelea striatula.

Other notable obsolete names include Pennant's rugosa (1777),[12] technically the first one to be coined, and Montagu's laminosa (1808),[13] which describes a deep water variety with almost lamellose ridges[4] As was convention at the time,[14] British conchologists paid attention practically exclusively to the animals' shells, and rarely to the animal itself.

Only in 1853 did Forbes and Hanley[4] describe the most reliable way to distinguish striatula from gallina: the former's siphonal tubes are fully joined, while the latter's are separate and much shorter.
