Short description Morphology
White to light yellow shell exterior with occasional dark markings; smooth shell surface; valves with 40 to 50 non-projecting or faint ribs around the center; crenulated shell margin.
Minimum depth based from occurrence (Ref. 2742); to be replaced with a better reference. Collected from the sublittoral zone, from low tide up to a depth of 200 m. It is found in substratum with generally coarse sand and gravel, often overlain with pebbles, cobbles and dead shell (Ref. 2742 and 2744). It's a sessile-burrower, suspension feeder (Ref. 96498).
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.
