Reproductive Biology

Little is known about the reproductive cycle of A. cistellula. It is thought to breed continuously, on the basis of the maturing eggs and larvae that are found in its brood pouches throughout the year. Each embryo goes through a gastrula stage as well as two-lobed and three-lobed stages. Before leaving the brood pouch, the larvae have an apical lobe with a ring of long cilia, a mantle lobe with a mid-ventral strip of cilia, and a pedicle lobe that lacks cilia. The larvae lack setae. Unlike most lampshells, A. cistellula is hermaphroditic, which means that each individual possesses both male and female gonads.

CONSERVATION STATUS Not listed by IUCN.
