Elasmobranchii 板鰓亞綱 (鯊魚與魟魚) (sharks and rays) > 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);  quagga: Etymology not explained, possibly referring to shark’s narrow vertical bars, similar to those of the zebra, Equus quagga. (See ETYFish).

簡短描述 檢索表 | 型態特徵 | 形態測量圖

A small shark with numerous (>20) vertical stripes on the body without dark spots, snout tip knoblike but not prominently upturned. Eyes in adults 12–13 times in distance from snout to first dorsal origin. Anterior nasal flaps sub triangular. Gills dorsolaterally placed and elevated above the mouth level. First dorsal-fin origin about opposite pelvic-fin insertion. Light brown above with pale ventral side, dark brown cross bands on the body (Ref. 86593).

生物學特性     字彙 (例如 epibenthic)

Found on the continental shelves, (Ref. 244), on or near the bottom (Ref. 30573). Attains a maximum size of 37.0 cm TL; female of 36.8 cm TL was gravid and contained eight egg cases, four in each uterus (Ref. 86593). Feeds on shrimps. Collection by deep-sea shrimp trawlers may indicate that the species could have a wider depth distribution, possibly down to 280 m (Ref. 86593). Not utilized at present (Ref. 244).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.2   ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
