Cardiidae

 

(cockles), a family of bivalve mollusks having a strong, ribbed, heart-shaped shell reaching 10 cm in length. The Serripes groenlandicus is among the largest of the approximately 250 widely distributed species. Cockles inhabit seas and brackish waters; they are found in all the seas of the USSR. The most common species, Cerastoderma edule, is 5–6 cm long. It is distributed along the western and northern coasts of Europe and in the Baltic, Mediterranean, Black, Caspian, and Aral seas; it entered the two last seas when they were connected with the Black Sea. C. edule and a few other species have commercial significance.

Due to the computational limitations, we selected nine clam species for a maximum likelihood analysis; one from subclass Pteriomorphia (Mytilus edulis) as an outgroup, two from zooxanthellate Cardiidae (Corculum cardissa and Fragumfragum), two from azooxanthellate Cardiidae (Vasticardium flavum and Fulvia mutica), two from the genus Tridacna (Tridacna gigas and T.
the tridacnid clams, genera Tridacna and Hippopus, are more closely related to the cardiids Vasticardium flavum and Fulvia mutica than these clams of Fragum and Corculum, suggesting either that the family Cardiidae is paraphyletic or that tridacnids belong to the family Cardiidae.
