Short description Morphology

Shell mussel-shaped, elongate, ventral region concave. Oblique ridge runs anterodorsal to posteroventral region of valve. Umbones subterminal. Posterior part of the mantle with branching tentacles. Colour: externally greenish on posterodorsal region (above ridge) and yellowish brown on anteroventral region (below ridge).

Biology     Glossary (e.g. epibenthic)

Intertidal in bays and protected areas, forming clumps attached to mangrove prop roots or other hard substrates (Ref. 344) via its byssus (Ref. 104222). Attached to mangrove roots, particularly on Rhizophorae mangle (Ref. 104222). Some found to be buried in substrate. Also occurs in a river estuary. Highly tolerant to salinity variations (Ref. 104223). Parasitic on this mussel are Rickettsia-like organisms, Apicomplexa and Platyhelminthes (Ref. 104222). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
