Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the phylum Brachiopoda are gonochoric. Eggs are shed into the water and fertilized at the time of spawning. Life cycle: Eggs develop into free-swimming larvae which later metamorphose into adult.
