Title

Notes on two sympatric species of deep-water Vesicomyidae (Mollusca, Bivalvia) from the central Gulf of California, western Mexico

Abstract

Two sympatric species of deep-water Bivalvia are reported from the Gulf of California, below the Oxygen Minimum Zone. The most abundant species was Calyptogena lepta (385 living specimens, 102 dead shells). The second species, "Pliocardia" stearnsii, was much less abundant (5 living specimens, 6 dead shells). Environmental data indicates that both species can tolerate mild hypoxic conditions. Size distribution of C. lepta indicates that most specimens (75%) were in the intermediate size range (shell length: 13.50 to 23.49 mm). No difference in the length-height relationship (R2, 0.9803) was observed between smaller (minimum length, 8.56 mm) and larger (maximum length, 33.39 mm) specimens of this species.
