Bivalvia | Ostreoida
Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 0 - 100 m (Ref. 348), usually 0 - 5 m (Ref. 348). Tropical
Indo-Pacific: from East Africa, to eastern Polynesia; north to Japan and south to Queensland and New Caledonia.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 11.0 cm male/unsexed; (Ref. 348); common length : 8.5 cm male/unsexed; (Ref. 348)
Maximum depth from Ref. 101147. Attached by its byssus to coral slabs, rubble under the slab (Ref. 101147), under coral heads and rocks (Ref. 348). Frequently encrusted by sponges, bryozoans, algae, and other marine growths. Able to swim actively for some distance when detached. Common in the intertidal and shallow subtidal zones (Ref. 348). Also occurs on rubble, soft sediments, and scattered reefs (Ref. 87907). At night, adults seem to move to open water to feed and return to rubble pile in the day (Ref. 101147). 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).
