Natural history
Grazes on seaweeds, and population density affects the rate of kelp settlement. Provides shelter for juvenile abalone Haliotis midae and is an important influence on kelp forest ecology. Abundant on flatter areas of rocky reefs in the Cape. Eaten by West coast rock lobster Jasus lalandii.[1][3]
