Environment: milieu / climate zone / depth range / distribution range
Benthic; freshwater; depth range 4 - 200 m (Ref. 83435). Tropical, preferred 18°C (Ref. 107945); 23°S - 42°S, 74°W - 42°W
Southwest Atlantic and Southeast Pacific: From Rio de Janeiro, Brazil to San Matiás Gulf, Argentina. In the Pacific it is found in Chile. Tropical to subtropical.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 12 - 13 cm Max length : 27.0 cm DL male/unsexed; (Ref. 83435)
Minimum depth range from Ref. 122063. Lives in shallow waters at maximum depths of 4 m during low tide. Found on sandy subtrates with boulders and sponges. Individuals spend most of their time buried. Females attach their egg capsules to benthic hard substrata such as mollusk shells and/or pebbles (Ref. 122063). Voracious predator on bivalves (Ref. 114777). Members of the order Neogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults (Ref. 833).
