Etymology: Galeorhinus: galeo, probably based on G. galeus (see below); rhinus, an ancient name for sharks, from rhine (Gr.), rasp, alluding to their rasp-like skin. (See ETYFish); galeus: From galeos, a small shark or dogfish per Aristotle (sometimes translated as weasel), possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks1. (See ETYFish).

背棘 (总数) : 0; 臀棘: 0. A large houndshark with a long, pointed snout, a large mouth, and small blade-like teeth; 2nd dorsal about as large as anal fin and terminal caudal lobe as long as rest of fin (Ref. 5578). Greyish above, white below; young with black markings on fins (Ref. 5578).
一个大的猎犬鲨具有一个长的，尖的吻, 一个大的嘴 , 与小的刀剑状的齿; 第二背鳍大约与臀鳍与末端的尾叶一样大长达其它的鳍。 (参考文献 5578) 背面略灰色的, 腹面白色的; 在鳍上幼鱼有黑色的斑纹。 (参考文献 5578)
Mainly demersal on continental and insular shelves, but also on the upper slopes, at depths from near shore to 550 m (Ref. 6871), but has been shown to be pelagic in the open ocean (frequently caught on floating tuna longlines over deep water, and many New Zealand-tagged specimens have been recaptured in Australia) (Ref. 26346). Occurs in small schools that are highly migratory in higher latitudes in their range (Ref. 244). There is pronounced partial segregation by size and sex in some areas (Ref. 244). Feeds on fishes (bottom as well as pelagic species, Ref. 26346), crustaceans, cephalopods, worms, and echinoderms (Ref. 244). Ovoviviparous (Ref. 50449). Targeted for human consumption, liver for squalene oil, fins for soup (Ref. 244); also utilized as fishmeal (Ref. 13563). Marketed fresh, dried-salted, and frozen (Ref. 9987). Adapts well in captivity if carefully captured and handled (Ref. 12951).
Ovoviviparous, without a yolk-sac placenta (Ref. 244). Embryos feed solely on yolk (Ref. 50449). 6 to 52 young in a litter (Ref. 26346). Litter size increases with the size of the mother. Embryos reach 30-36 cm TL at birth (Ref. 6080). In the southern waters of Australia, newly born and older juveniles (30-70 cm long) aggregate in 'nursery areas' found in shallow waters.They move to deeper coastal waters to over-winter. The following spring finds most of these young returning to their nursery areas. The older ones, aged 2 years and over move instead to eastern Bass Strait where most of the immature stock are found. The length of an average full-term embryo is 32 cm. Spawning frequency is once every year, ovulation occurring in early summer and parturition is completed by January of the following year. Gestation period lasts for about 12 months (Ref. 6390, 6871).西大西洋: 巴西南部到阿根廷。 東大西洋: 冰島到南非, 包括地中海。 西印度洋: 南非。 西南太平洋: 澳洲與紐西蘭。 中太平洋: 夏威夷。 東太平洋: 到在墨西哥的下加利福尼亞南部與加州灣的加拿大卑詩省; 祕魯與智利。
