Four new species and a new genus of lucinid bivalves are described from shallow and deeper waters in the Indian and West Pacific Oceans. The new genus Scabrilucina (subfamily Lucininae) includes the little-known Scabrilucina victorialis (Melvill, 1899) from the Arabian Sea and Scabrilucina vitrea (Deshayes, 1844) from the Andaman Sea as well as a new species Scabrilucina melvilli from the Torres Strait off northeastern Australia. Ferrocina brunei new species (Lucininae) was recovered from 60 m near oil drilling activities off Borneo; its anatomy confirmed the presence of symbiotic bacteria. Two unusual deeper water species of Leucosphaerinae are described, both species included in on-going molecular analyses; Gonimyrtea ferruginea from 400-650 m in the southwest Pacific and Myrtina reflexa from 200-825 m off Zanzibar and Madagascar.

Like many marine invertebrates, marine lucinid clams have an intimate relationship with beneficial sulfur-oxidizing bacteria located within specialized gill cells known as bacteriocytes. Most previous research has focused on the symbionts in the gills of these (and other) symbiotic bivalves, often assuming that the symbionts only persistently colonize the gills, at least in the adult stage. We used 16S rRNA gene sequencing and digital polymerase chain reaction with symbiont-specific primers targeting the soxB gene on the foot, mantle, visceral mass, and gills of the lucinid clam Loripes orbiculatus.

A whale fall community of chemosymbiotic invertebrates living on cetacean bones has been identified off southwestern Australia during a Remotely Operated Vehicle (ROV) survey at bathyal depths within the Bremer Marine Park, which is part of important marine mammal areas (IMMA) of the Albany Canyon Region. Cetacean bones on the seafloor of the Hood Canyon, consisted of isolated skulls of three species of beaked whales (family Ziphiidae): cf. , , and , a few vertebrae, and lower jaws.

In seagrass sediments, lucinid bivalves and their chemoautotrophic bacterial symbionts consume HS, relying indirectly on the plant productivity for the presence of the reduced chemical. Additionally, the role of lucinid bivalves in N provisioning to the plant (through N fixation by the symbionts) was hypothesized. Thus, lucinids may contribute to sediment detoxification and plant fitness.

Bivalves from the family Lucinidae host sulfur-oxidizing bacterial symbionts, which are housed inside specialized gill epithelial cells and are assumed to be acquired from the environment. However, little is known about the Lucinidae life cycle and symbiont acquisition in the wild. Some lucinid species broadcast their gametes into the surrounding water column, however, a few have been found to externally brood their offspring by the forming gelatinous egg masses.
