Ökologie
seewasser bathydemersal; standorttreu; tiefenbereich 540 - 2070 m (Ref. 1371). Deep-water; 33°S - 50°S, 137°E - 179°W (Ref. 1371)
Southwest Pacific: New Zealand, Tasman Sea, south of Tasmania, southeast Australia (Victoria), and possibly also across the Indian Ocean (Ref. 1371). A possible subspecies, Coryphaenoides serrulatus oceanus from the Indian Ocean (Walters Shoals south of Madagascar to Broken Ridge in 870-1,255 m) is recognized by Iwamoto and Shcherbachev (Ref. 10993).
