Description
editMimachlamys asperrima has a shell which can reach an adult size of 11 centimetres (4.3 in).[4] Like almost all scallops, the shell is fan-shaped and composed of two valves, each of which is convex and has broad ribs. The ribs radiate from the umbo, the rounded protuberance near the hinge. Again, like all scallops, beside the hinge are two irregular shelly flaps or auricles; the anterior one is normally much larger than the posterior one. Like all scallops the interior of each valve shows a central round scar which is the attachment area for the single strong adductor muscle which closes the two valves of the shell. The background color of the exterior of the shell in this species varies from yellow to light purple. Like almost all bivalve species, this one is a filter feeder, sieving microscopic algae from water that passes through its gills.
Distribution and habitat
editThis species is endemic to coastal Southern Australia.[2][4] It lives in crevices in reef and sand areas down to a depth of 30 metres (98 ft).[4]
