Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 2 - 2.5 cm Max length : 25.0 cm ShL male/unsexed; (Ref. 356)

This species is one of 5 Haliotis species endemic to South Africa. It is the largest and most abundant of the abalone species in this country.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Broadcast spawner. No mating behavior. Spawning is initiated by the release of sperm cloud stimulating the females to release their eggs. Life cycle: Eggs hatch into trocophore larva moving actively in the water column and shortly after develops into veliger larvae, followed by substrate settlement and metamorphosis.
