The Burry Inlet Cockle Fishery of this species has been certified by the Marine Stewardship Council (http://www.msc.org/) as well-managed and sustainable (http://www.msc.org/html/content_486.htm). Found in shallow coastal and estuary areas (Ref. 95774); in the subtidal zone (Ref. 96507). Inhabits the seagrass meadows Zostera noltii and Cymodocea nodosa in sand flats (Ref. 106872). Also found on intertidal muddy sand flat. Infaunal (Ref. 106873). A deposit (Ref. 96459), and suspension feeder (Refs. 96498, 106872, 106873) that is a sessile-burrower (Ref. 96498). Feeds on microphytobenthos and particulate organic matter (Ref. 106873).
ライフサイクルと交尾行動
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
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.
