Chimaeriformes (Chimaeras) >
Chimaeridae (Shortnose chimaeras or ratfishes)
Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors (See ETYFish); affinis: Latin for related, referring to its similarity to Chimaera monstrosa (See ETYFish).

生态学
海洋 深海底的; 深度上下限 300 - 3000 m (Ref. 117245). 深水域; 70°N - 58°S, 80°W - 41°E
Northeast Atlantic: Rockall Trough along Ireland, northern Bay of Biscay and off Portugal. Reported from Iceland (Ref. 12462). Southwest Atlantic: Uruguay (Ref. 58839). Northwest Atlantic: Newfoundland in Canada to Cape Cod in USA. Probably has a much wider distribution. Possibly occurring off the Cape in South Africa and off Mozambique (Ref. 11228).
東北大西洋: 沿著愛爾蘭，比斯開灣北部與葡萄牙外海的 Rockall 溝槽。 記錄來自冰島了。 (參考文獻 12462) 西北大西洋: 加拿大的紐芬蘭到美國的科德角。 可能有一個非常寬的分布。 可能地出現外海的在南非與莫三比克外海中的岬.(參考文獻 11228)

缺乏一个分开的臀鳍。 胸鳍不会重叠腹鳍。 短的尾丝。 深褐色的颜色.(参考文献 6902)
Epibenthic (Ref. 58426). Found on continental slopes and down to deep-sea plains. Reported down up to 3000 m along the mid-Atlantic ridge (Ref. 83979, C.Cotton pers.comm. 03/10). Feeds on small fishes and invertebrates (Ref. 6680). Oviparous (Ref. 205). Eggs are encased in horny shells (Ref. 205). It is commercially used as fish meal and to produce high-quality machine oil from the liver (Ref. 117245).
