Bivalvia |
Venerida |
Cyrenidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; freshwater; brackish. Tropical
Western Central Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 15.0 cm SHL male/unsexed; (Ref. 348); common length : 10.0 cm SHL male/unsexed; (Ref. 348)
Locally collected for food (Ref. 348). Author and year is (Lamarck, 1818) in Ref. 3477. Also found in the banks and river beds, in fresh and brackish, often running water. Often lays buried with the hind tip of the shell emerging at the surface of the sediment with siphons slightly projecting between the valve margins. Capable of living deep within the sediment, with no siphonal access to the surface, to endure drought periods, then feeding from subterranean water through a narrow anterior gape of shell (Ref. 348).
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.
