Biology:Vesicomyidae

From HandWiki

Vesicomyidae is a family of saltwater clams, marine bivalve molluscs in the superfamily Glossoidea.[1] They thrive in communities of sulphide-rich reducing environments, at depths from 100 to 9050 m.[2]

Vesicomyidae is very often studied to understand molecular adaptation to extreme deep-sea environments and biogeography. Studies of Kenzoic fossile figures show that Vesicomyidae has lived in this type of habitat since late Eocene, 42-47 millions of years ago.[3] The taxonomy foor this family is currently under revision as there is a discrepancy between molecular data and morphological data.[4]

Swedish researcher Frida Hybertsen has shown in her dissertation that the difference in size of the Vesicomyidae between Eocene to the Oligocene might be due to climate change.[5]

Vesicomyidae has been found at the underwater Piip Volcano in the Bering Sea, off the Puerto Rican coast[6] and more recently in the Ross Sea.[7]
