Etymology: Dalatias: Etymology not explained nor evident. A few online sources suggest Dalatias is derived from dalos (Gr.), torch or firebrand, but nothing in Rafinesque’s description supports this interpretation. Interestingly, D. licha is bioluminescent, a fact that was discovered and resported only recently and was certainly unknown to Rafinesque and other early naturalists. See: Mallefet J., D. W. Stevens, and L. Duchatelet. 2021. Bioluminescence of the largest luminous vertebrate, the kitefin shark, Dalatias licha: first insights and comparative aspects. Frontiers in Marine Science 8 (article 633582): 1-13 (See ETYFish); licha: Latinization of “La Liche” as reported by Broussonet (1780), an old French word for this shark, possibly from from the Occitan lecha or lec, meaning “glutton” (See ETYFish).

简单描述 检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 0; 臀棘: 0. Moderately sized, short- and blunt-snouted shark with two almost equal-sized dorsal fins; papillose thick lips; small slender-cusped upper teeth and very large lower teeth with erect triangular serrated cusps and distal blades; first dorsal fin on back with its origin behind the pectoral rear tips and its base closer to the pectoral base than the pelvic fins; and caudal fin with the ventral lobe not expanded (Ref. 247). Dark grey-brown to black; trailing edges of fins translucent (Ref. 26346).
Body shape (shape guide): elongated.
中等大小的, 短- 与吻钝的鲨鱼有二几乎相等的-大小了背鳍; 乳突状的厚唇; 小的尖端细的上颚齿与非常大的下颚齿有直立的三角形的锯齿状的尖头与末梢部的叶片; 第一背鳍背面有之上它的起点在胸的后顶端与它的基底后面更靠近超过腹鳍的胸鳍基底; 而且尾鳍有不被扩大的腹的叶.(参考文献 247) 暗灰褐色的到黑色的; 鳍的蔓缘半透明的.(参考文献 26346)

生物学特性     字汇 (例如 epibenthic)

Found on outer continental and insular shelves and slopes (Ref. 247). Mainly found on or near the bottom but readily occurs well off the substrate (Ref. 247, 58302). Often pelagic (Ref. 58302). Found singly or in small schools (Ref. 6871). Feeds mainly on deepwater bony fish, but also skates, other sharks (etmopterids in Ref. 123656), cephalopods and crustaceans (Ref. 5578). This bioluminescent shark (currently the largest luminous vertebrate) emit light ventrally to counterilluminate which might be used to illuminate the ocean floor while searching/hunting for prey; or to stealthily approach prey, using counterillumination camouflage, before striking fast when it is close enough (Ref. 123656). Ovoviviparous (Ref. 205), with 10-20 young born at 30-42 cm (Ref. 26346). Used for its squalene liver oil, leather and meat, as well as for fishmeal (Ref. 6871).
