Planktotrophic planktonic larva (feeding)

Asexual Reproduction:

Does not reproduce asexually

Reproduction Details:

External fertilization; gonochoristic/ dioecious; broadcast spawning; planktotrophic planktonic larva (feeding); does not reproduce asexually (M. Otani, pers. comm.) RELATED: [Bivalvia] without copulatory organs, only suited for external insemination; release gametes into water, where fertilization occurs; gamete structure designed for necessity of water movement: spermatozoa have long tail; well developed mitochondria; acrosomes designed to destroy egg membranes (Drozdov 2009)

Adult Mobility:

Facultatively mobile (Species with limited mobility, in particular to repositioning themselves in response to environmental disturbances (e.g., sea anemones))

Adult Mobility Details:
