Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Life cycle: Egg develops into the first free-swimming larval stage (trocophore) within 4 to 24 hours, afterwhich it develops into a veliger larvae within 24 to 48 hours. The veliger secretes the first larval shell within 10 to 12 hours, which then develops into a velichoncha larvae which secretes the second larval shell. It further develops into pediveliger, with a characterized foot making it mobile to find a suitable substrate and able to feed. It metamorphoses into a post-larval mussel called plantigrade (Ref. 104799).
