It is found in kelp beds on rocky and soft bottoms, from low intertidal to a depth of 69 meters (Ref. 865). Also inhabits sand areas adjacent to more solid substratum. Forms aggregated distribution patterns, most likely as a foraging and/or reproductive strategy. Carnivorous scavenger. Primarily feeds on live sessile polychaetes and solitary tunicates (Ref. 101624). Members of the order Neogastropoda are mostly gonochoric and broadcast spawners (Ref. 833). Life cycle: Eggs capsules (400 to 1200 eggs) are deposited on hard substrate. Embryos develop within the capsule, emerge into the water column as free-swimming veliger larvae and later assumes a benthic life style (Ref. 104623).
