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); trolli: In honor of American artist Ray Troll (b. 1954), Ketchikan, Alaska (USA), “one of the few true chimaeroid lovers of the world ... for his valiant efforts to increase ratfish awareness worldwide” (See ETYFish).
Eponymy: Dr Raymond ‘Ray’ Michael Troll (d: 1954) is an American artist (he calls himself a “fin artist”), musician, humourist and illustrator. [...] (Ref. 128868), visit book page.

簡短描述 檢索表 | 型態特徵 | 形態測量圖
Body blue-gray with a dark line around the orbit and dark shadowing along edges of lateral-line canals. Snout pointed. Preopercular and oral lateral-line canals sharing a common branch. D1 concave with pale margin. Males with frontal tenaculum deeply curved, upturned distally with spines along dorsal upturned edge. Prepelvic tenacula deeply indented along distal margin. Pelvic claspers with pale fleshy distal lobes, divided distally for 1/3 their length, tips usually extending beyond distal edge of pelvic fins. Ventral caudal fin not deeply indented at its origin to form a separate anal fin.
Body shape (shape guide): elongated; Cross section: compressed.
身體藍灰色的具有一個眼窩的周圍黑色線條與深色的遮蔽沿著側線管的邊緣。 吻端尖的。 前鰓蓋骨與口部的側線管共用一個分枝。 D 1 凹的有灰白的邊緣。 雄性有前的把鉤深深地彎曲, 朝上的末梢部地和棘沿著背部的朝上邊緣。 腹鰭前的把鉤深深凹入的沿著末梢部的邊緣。 腹鰭釦緊物有灰白的對於 1/3 他們的長度末梢部地被分開的肉質的末梢部的葉，頂端通常延伸超過腹鰭的末梢部邊緣。 腹面尾鰭不深深地在它的起源切割成鋸齒狀形成一個分開的臀鰭。
