Bathymodiolus childressi is a species of deepwater mussel, a marine bivalve mollusk species in the family Mytilidae, the mussels.

Although this species has been known since 1985,[2] it was formally described as a species in 1998.[1]

Habitat[edit]

This species lives in cold seeps in the Gulf of Mexico.[3]

Bathymodiolus childressi is stenothermal species living in temperatures ranging from 6.5 to 7.2°C.[4] However it was able to survive the temperature of 20°C in the laboratory.[4]

Symbiosis[edit]

This mussel harbors intracellular methanotrophic bacteria in its gills.[2] The bacteria provide carbon to the mussel.

Interspecific relationships[edit]

The snail Bathynerita naticoidea can detect beds of the mussel Bathymodiolus childressi. It is attracted to water that has been altered by this species of mussel,[3] but the nature of the attractant was not discovered yet.[3] This snail also feeds on periphyton of methanotrophic bacteria that grow on the shells of Bathymodiolus childressi,[3] living on the decomposing periostracum of the mussels[3] and on byssal fibres of those mussels.[3]

Etymology[edit]

This species was named after James J. Childress, a marine biologist who investigated the physiology of this mussel at the University of California, Santa Barbara.[5]
