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).

生物学     用語集 (例 epibenthic)

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).
