Environment / Climate / Range
Benthic; depth range 0 - 55 m (Ref. 104365). Tropical; 36°N - 23°N, 98°W - 74°W
Western Central Atlantic: North Carolina to Texas, USA and Mexico.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 15.0 cm DL male/unsexed; (Ref. 83435); common length : 15.0 cm TL male/unsexed; (Ref. 344)
Shell elongate, ovate. Surface glossy. Sculpture almost completely absent, except for weak growth lines and radial riblets. Lunule oval. Long external ligament. Colour: salmon to greyish purple, with darker, brownish radial bands; lunule purplish.
Fisheries: Commercial production ceased in Florida in 1973. Lives in sandy bottoms (Ref. 344). Suspension/ filter feeder (Ref. 104247). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088). Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
