Ecology

Habitat

Habitat Type: Marine

Comments: The conchaphila form is usually attached to living mollusks or the carapace of large crustaceans and is usually solitary while the lurida form is attached to dead shells or rocks and may form extensive reefs (Coan et al., 2000).

Ostrea conchaphila

Ostrea conchaphila is a species of oyster, a marine bivalve mollusk which lives on the Pacific coast of Mexico south of Baja California. Until recently there was some confusion as to whether this more southern oyster species might in fact be the same species as Ostrea lurida, the well-known but more northerly "Olympia oyster", which it resembles in shell size and color. Because of this confusion, the name O. conchaphila was sometimes applied to various populations of what is now known to be O. lurida.

Recent molecular evidence supports the idea that this species is a separate, more southerly species.[1]

Distribution[edit]

This species occurs on the West Mexican coast south of Baja California. There was previously some disagreement about whether this species was distinct from Ostrea lurida, the Olympia oyster, a species which lives north of Baja California.[2]

Others have considered it more plausible that the Olympia oyster is a more northern species, distinct from O. conchaphila...
