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).

简单描述
检索表 | 型态特徵 | 形态测量图
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.
栖息于大陆架外缘与上层斜坡了。 吃多种小鱼 (例如灯笼鱼) 与无脊椎动物。 卵生的。 持有一个扩大的鳃部是适应低容氧量地区。 有一个 squalene 的高集中在它的肝脏内那一个提供它中性浮力。 经常地被底拖网捕获了但是一点也没被利用。
