Ruditapes largillierti is a saltwater clam, a marine bivalve mollusc in the family Veneridae, the Venus clams. They are moderately large for their genus (45–65 mm long), elongate and subrectangular, thick and solid, with smooth ventral margin.[1]
The species has limited use to people and the seafood industry because it resides in very deep ocean water and contains a very common pearl.
