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); matallanasi: In honor of Jesús Matallanas Garcia, University of Barcelona (Spain), for his “extensive work and tireless dedication to ichthyology”. (See ETYFish).

简单描述
型态特徵 | 形态测量图
Diagnosis: Differs from its congeners in having an irregular brown coloration with reticulations and spots over the body; ventral surface whitish, including pectoral bases; proximal margin of the second dorsal fin whitish; tooth plates striped and bicolor, yellowish and gray; length of dorsal fin spine equal to or slightly greater than head length; pectoral fin notably long, its tip extending beyond posterior margin of pectoral fin base; upper margin of second dorsal fin notably concave at middle region of second dorsal fin base; minimum height of second dorsal fin less than half of maximum height (located at points anterior and posterior to middle region of fin); eye length slightly smaller than preorbital length (Ref. 52554).
Female maximum length given as precaudal length (PCL). Inhabits deep-reefs on the continental slope, usually deeper than 400 meters; with gorgonians, hard corals, tube sponges, crinoids, and ophiuroids. It also shares this habitat with other sharks Heptranchias perlo, Scyliorhinus haeckelii, Galeus mincaronei, Schroederichthys saurisqualus, Squalus sp., and the skate Gurgesiella dorsalifera (Ref. 52554).
