Carcharhiniformes (Ground sharks) >
Pentanchidae (Deepwater catsharks)
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).

生態学
海 底生の; 深さの範囲 80 - 100 m. Subtropical; 39°N - 20°N
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).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 40 - ? cm
Max length : 49.0 cm TL オス/雌雄の選別がない; (Ref. 244)
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).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
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.
