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. Found on rocky reefs between the intertidal and subtidal zones up to a depth of 10 m (Ref. 81186).
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.
