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).
Eponymy: Jesús Matallanas Garcia is a Spanish ichthyologist and Professor in the Faculty of Biosciences at the University of Barcelona. [...] (Ref. 128868), visit book page.

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).
鉴别: 在有一个方面有别于它的同类不规则的褐色体色和在身体上的网眼与斑点; 腹面微白色的, 包括胸鳍基底; 第二个背鳍的近端边缘微白色的; 齿板有斑纹与双色的, 淡黄色的与灰色; 背鳍长棘等于或些微大于头长; 胸鳍特别地长的, 它的顶端延伸超过胸鳍基底的后缘; 第二背鳍鳍的上缘特别地在第二背鳍鳍的基底的中央区域凹曲; 第二背鳍鳍的最小量高度少于一半的最大高度;(位于了点前面与后面的到鳍的中央区域) 眼径些微地比眶前骨长度更小.(参考文献 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).
最大的长度被当作尾前椎长度 (PCL)了。 深地栖息于-在大陆斜坡上的礁, 通常深度超过 400 公尺; 与柳珊瑚，坚硬的珊瑚，管海绵，海百合类动物与阳燧足。 它也与其他的鲨鱼 Heptranchias perlo ， Scyliorhinus haeckelii 分享栖地, Galeus mincaronei, Schroederichthys saurisqualus, Squalus sp., 与魟鱼 Gurgesiella dorsalifera.(參考文獻 52554)
