Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 0 - 49 m (Ref. 83435). Tropical
Western Atlantic: Caribbean to northeast Brazil.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 18.0 cm TL male/unsexed; (Ref. 271)
Diagnostic features: Shell light, thin, elongate. Sculpture of concentric ridges and strong radial ribs. Scale-like projections form at intersections of ridges and ribs. Pair of spoon-shaped structures under umbones, called apophyses, are points of attachment of foot muscles. Colour: pure white, seldom with delicate pinkish internal coloration (Ref. 271).
It has an assumed maximum total length of 18 cm (Ref. 271). Maximum depth from Ref. 104365. It is found infaunal in compact mud or sand, from intertidal to shallow subtidal depths. Borer in mud bottoms in protected bays (Ref. 271).
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.
