Lucinidae – Lucina Clams

Description A large, well-known family of usually white, hard-shelled clams in which the cardinal teeth are small, and the anterior muscle scar is narrow and long. There are no long siphons, so the clams make a tube to the surface with their foot. Many genera and species, worldwide, shallow to deep water. The tropical clam Lucina pectinata contains a unique hemoglobin (HbI) which serves to transport hydrogen sulfide to autotrophic bacteria that live endosymbiotically (within the host’s tissues). The bacteria provide a clear example, as to how these clams survive in both the oxic sea environment and the hypersaline, anoxic environment near sea floor vents. Mutualisms like this example are ancient and underscored by multiple lines of evidence (Hickman, 2003).
