生態學
海洋 深海底的; 非遷移的; 深度上下限 600 - 1500 m (Ref. 1371). 深水域; 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.
東印度洋: 溫帶澳洲。 東南太平洋: 加拉巴哥群島與外海的智利中部。 二個亞種被辨認出, 來自智利的 銼鱗奈氏鱈〔Nezumia loricata〕 loricata 從加拉巴哥島與 銼鱗奈氏鱈〔Nezumia loricata〕 atomos。 智利的與澳洲的記錄建議橫過南太平洋的一個寬的溫帶分布。
