, though the left valve is more convex than the right. The
auricles, ear-like projections on either side of the hinge, are inequal in size, with the anterior always being much larger than the posterior. The
byssal notch is deep, and the valves are generally similar in sculpture.
Distribution and habitat
The habitat for this genus is temperate oceans down to a depth of several hundred meters, from southern Australia to Indonesia and north to the Philippines. Some species in the genus ''Mimachlamys'' retain their byssal threads through adulthood, and are not free swimming.
