Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; brackish; depth range 0 - 2 m (Ref. 83435). Tropical; 37°N - 18°N, 97°W - 75°W
Western Atlantic: Virginia, USA to Campeche Mexico.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 4.0 cm SHL male/unsexed; (Ref. 83435)
Shell outline subtriangular, as high as long, inflated, heavy. Shell smooth, sculpture absent. Hinge with three cardinal teeth situated under umbo; 1 anterior and 1 posterior lateral tooth. Ligament long, narrow. Periostracum with minute scales, fuzzy, thin. Colour: externally dull white, internally white rarely stained with purple; periostracum glossy brown (Ref. 344).
It has a total length of 3.5 cm. Fisheries: It is consumed locally boiled, restrictions due to habitat degradation hamper exploitation in parts of area (Ref. 344). It is infaunal in mud or sandy mud in estuaries, mangrove swamps, and coastal lagoons (Ref. 344). Occurs in intertidal areas and in relatively small numbers in shallow nearshore areas (Ref. 104487).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
