Taxonomic Remarks
Squalus suckleyi (Girard, 1855) has been resurected by Ebert et al. (2010: Ref. 85328) in the North Pacific where it replaces Squalus acanthias Linnaeus, 1758.

Possibly the most abundant living shark (Ref. 247). A demersal, inshore and offshore dogfish of the continental and insular shelf and upper slopes (Ref. 247, 11230, 119696). Usually near the bottom, but also in midwater and at the surface (Ref. 26346). Adults occur mainly between 10-200 m depth (Ref. 247). Males and gravid females usually found shallower than non-gravid females. They tolerate brackish water, often found in enclosed bays and estuaries. Reported to enter freshwater (Ref. 11980) but cannot survive there for more than a few hours (Ref. 247). Highly migratory species, used to be observed in large foraging schools with up to thousands of individuals, usually segregated by size and /or sex, with schools of large gravid females preferentially targeted by fisheries. Their latitudinal (north-south) and depth-related (nearshore-offshore) movements appear to be correlated with their preferred temperature (Ref. 247). Tagging experiments showed that populations in the northern North Sea and northwest Scotland made winter migrations to off Norway and summer migrations to Scotland (Ref. 88880, 88881). Transoceanic migrations recorded, but rare (Ref. 88864). Longevity in the northern Atlantic is about 35-50 years (Ref. 88882), but most live only 20-24 years (Ref. 88187). Growth is slow. At sexual maturity, males are 60-70 cm long, females 75-90 cm (Ref. 35388). Gestation period is 2 years (Ref. 36731). Ovoviviparous (Ref. 205). Feeds on a diversity of prey, ranging from comb jellyfish, squid, mackarel and herring to a wide array of benthic fishes, shrimps, crabs and even sea cucumbers (Ref. 93252). The only species of horned sharks that can inflict toxins with its tail. Detects weak electric fields generated by potential prey (Ref. 10311). Utilized for human consumption, liver oil, vitamins, sand paper, leather, fertilizer, etc. (Ref. 247, 27436). Eaten fried, broiled, and baked (Ref. 9988).

Distinct pairing with embrace (Ref. 205). Ovoviviparous, with litters of 1 to 21 young (Ref. 247, 88865). Mating probably occurs in winter. Gestation period of 18 to 24 months, longest known of all chondrichthyans (Ref. 26346). Size at birth 18-30 cm (Ref. 26346). In the northeast Atlantic, pups are born in winter, with size at birth about 26-28 cm (Ref. 88864). Sex ratio at birth is 1:1. Gravid females congregate in enclosed shallow bays to give birth (Ref. 247). The mother shark experiences a series of rhythmic contractions, just like in mammals, and the young are delivered head first. Larger older females have bigger litters with larger pups; a female with 100 cm TL carries on average 4 times as many embryos compared to a 70 cm female and the former have higher survival rates than those born to small females (Ref. 4856, 88869, 88883).
