Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays)
(Ground sharks) > Pentanchidae
Etymology: Halaelurus: halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish); buergeri: In honor of German physician-biologist Heinrich Bürger (ca. 1804-1858), who collected and illustrated Japanese flora and fauna and apparently collected holotype of this species. (See ETYFish).

Northwest Pacific: Japan, Korea, China, and Taiwan (Ref. 244). May also occur in the Philippines (Ref.58048). Collected less than a degree west of the northwestern boundary of the Western Central Pacific (Ref. 11146); may consist of a species complex in the area (Ref. 47737).

Found on the continental shelf; sublittoral zone above 100 m (Ref. 11230). Oviparous, but with several egg-capsules retained in the oviduct until the embryos reach an advanced stage before they are laid which might be regarded as being intermediate between oviparity and ovoviviparity. Diet unknown, but presumably dominated by small invertebrates and fishes. Caught irregularly by demersal longline fisheries operating offshore. Utilized for its meat but of limited value due to its small size (Ref.58048).
栖息于大陆架了; 亚潮带超过100公尺.(参考文献 11230) 卵生的, 但是有多个卵鞘在输卵管中直到胚胎到达一个成长期才产出因此可被视为介于 oviparity 与 ovoviviparity 之间。

Oviparous, females depositing between 6-12 oval-shaped egg cases (Ref.58048). Eggs are kept in the oviduct until ready to be hatched. Reproductive strategy lies midway between oviparity and ovoviviparity. Species however, is classified as oviparous.西北太平洋: 日本，韓國，中國與台灣。 收集少於一個程度位於中西太平洋的西北分界西方.(參考文獻 11146)
