Short description Morfologi

Diagnostic features: Shell large, fan-shaped, triangular. Surface sculpture of about 15 narrow radial ribs separated any larger interspaces; ribs bearing regularly spaced, fluted spines. Large muscle scar inside shell touches border of nacreous area. Hinge area straight, representing larger side of triangular shell outline. Byssus at pointed extremity anchors penshell into seagrass bottom. Gaping shorter side of triangular shell outline oriented upward. Colour: dark olive brown; mantle colour bright golden orange. Fisheries: Commercially exploited in and around Campeche, Mexico. Consumed locally in soups, marinated, or grilled (Ref. 271).

Biologi     Ordlista (t.ex. epibenthic)

Habitat: Found in shallow-water seagrass beds. Behavior: Burrows in fine sand leaving only a broad posterior region exposed to the outside environment. Predator: horse conch, Pleuroploca gigantea (Ref. 271).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | 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.
