Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino batidemersale; non migratori; distribuzione batimetrica 600 - 1500 m (Ref. 1371). Deep-water; 3°N - 43°S, 114°E - 71°W (Ref. 1371)
Eastern Indian Ocean: temperate Australia. Southeast Pacific: Galapagos Islands and off central Chile. Two subspecies are recognized, Nezumia loricata loricata from the Galapagos and Nezumia loricata atomos from Chile. The Chilean and Australian records suggest a broad temperate distribution across South Pacific.
