Etymology: Parmaturus: parma (L.), from parme (Gr.), small shield; oura (Gr.), tail, presumably referring to upper edge of caudal fin “armed with modified” scales (per Garman 1913). (See ETYFish); xaniurus: xanion (Gr.), comb for carding wool; oura (Gr.), tail, referring to crest-like row of tooth-like projections along upper edge of caudal fin. (See ETYFish).

Found on the outer continental shelf and upper slope. Feeds on a variety of small fish (e.g. lanternfish) and invertebrates. Oviparous. Possesses an enlarged gill region which is an adaptation to areas with low dissolved oxygen levels. Has a high concentration of squalene in its liver which affords it neutral buoyancy. Regularly caught by bottom trawlers but not utilized at all.
