Venus gallina <4 cm. One of the dominant species on sandy bottom. Its density being reduced in Black Sea in last years.


Donax trunculus <4 cm. Dominant bivalvian species of Black Sea sandy shallows


Scapharca inaequivalis <8 cm. Evolutionary old bivalve of Indo-Pacific origin, invaded the Black Sea in 1960s. One of the dominant species on sandy bottom to 40m depth. Edible bivalve  with orange-yellow flesh


Cerastoderma lamarcki <7 cm, possibly extinct in the Black Sea,  completely eaten by Rapana venosa.


Cerastoderma glaucum <4 cm, became rare in the Black Sea, whereas it's one of the dominant bivalvian species in the Sea of Azov


Parvicardium exiguum <8 cm,

very rare in the Black Sea


Pitar rudis <2 cm, one of the dominant

species of the Black Sea sandy bottom at 10-40m depth


Polititapes aurea <4 cm,

became rare species in the Black Sea


Spisula triangula <2.5 cm,

common species of sandy bottom


Moerella (Tellina) tenuis <2 cm,

annual species


Moerella (Tellina) donacina <2 cm, lives in soft sediments deeper than 10m, annual species


Gouldia minima <0.7 cm, lives in soft sediments deeper than 10m; one of dominant species as recently as 1980s, rare species in the Black Sea now, eaten by Rapana venosa whelk


Lucinella divaricata <0.5 cm, one of dominant annual species of the Black Sea shallow sandy bottom


Lentidium mediterraneum <0.7 cm, one of dominant annual species of shallow sandy bottom


Solen vaqina <15 cm. Digs deep (to 1m) into the sand, becoming a rare species


Gastrana fragilis <5 cm. Became

a very rare species in the Black Sea due to the Rapana venosa pressure


Donacilla cornea <1.5 cm. Once one of the dominant species of sandy bottom, almost disappeared now, at the Caucasian coast at least


Loripes lucinalis <1.2 cm. Once one of the dominant species of sandy bottom,

became rare in the Black Sea due to the Rapana venosa pressure


Mactra corallina <7 cm, rare species

in the Black Sea


Mya arenaria <10 cm. Invaded Black Sea from Atlantic in 1960s. Prefers brackish water, one of dominant bivalves in the Sea of Azov


Mercenaria mercenaria <15 cm. No findings of live mollusks of this species


Galactella lactea <0.5 cm. Very small and very rare bivalve of Arcidae family

in the Black Sea


Modiolus phaseolinus <4 cm. Most abundant bivalve in the Black Sea. Dominant species deeper then 40m. Most of the bottom sediments at those depths originate from Modiolus shells


Flexopecten ponticus, Black Sea scallop - <7 cm. Considered to be extinct since late 1990s - eaten by Rapana venosa whelk. Fresh 0.5 cm scallop shell was found in 2008 near Tuapse, so that mollusk was alive in 2007 at least.
