Etymology: Furgaleus: fur, Latin for thief (Whitley said “‘shark’ or villain”); galeus, Greek for weasel, an ancient name for sharks perhaps alluding to what some may have perceived as a weasel-like body or pointed snout [replacement name for Fur Whitley 1943, preoccupied by Fur Jones 1940 in Diptera]. (See ETYFish); macki: In honor of British-born ichthyologist-ornithologist George Mack (1899-1963), National Museum, Melbourne, Australia. (See ETYFish).

Ecologia
marino demersale; distribuzione batimetrica ? - 220 m (Ref. 6871). Temperate; 21°S - 45°S
Eastern Indian Ocean: southern Australia.
Length at first maturity / Size / Peso / Age
Maturity: Lm 112.0, range 120 - ? cm
Max length : 160 cm TL maschio/sesso non determinato; (Ref. 6871); peso massimo pubblicato: 12.9 kg (Ref. 6390); Età massima riportata: 12 anni (Ref. 35585)
Found on the continental shelf, commonly on rock bottom, seaweed and kelp beds. Feeds on octopi, squid, bony fishes and lobsters. Peanut worms and seagrass are also included in their diet (Ref. 6390). Ovoviviparous, with 5-24 in a litter (Ref. 6871). Young are 20-25 cm long at birth (Ref. 13840, 244). Marketed fresh for human consumption.
Ovoviviparous but aplacental. Stock sex ratio is 1:1 (Ref. 13839). Gives birth in spring or early autumn (Ref. 6871). Litter size is 5-24 (Ref. 6871). In the Western Australian population, ovulation and early pregnancy take place between January and March. Gestation period probably lasts for 9-12 months. Each female probably does not breed every year.
