Carcharias taurus generally occurs in warm-temperate and sub-tropical waters, ranging from the surf zone and shallow bays to approximately 200 m depth on the outer continental shelf. The species is most usually found on or near the bottom in reef areas but may occasionally occur in midwater or at the surface (Compagno 1984). In NSW and southern Queensland, C. taurus is most frequently sighted in or near sandy-bottomed gutters or in rocky caves, often around inshore rocky reefs and islands at depths of between 15 and 25 m (Pollard et al. 1996, Otway and Parker 1999).
Embryonic oviphagy and intra-uterine cannibalism occurs in this species and only two large pups are produced per litter every second year. As a result, annual rates of population increase are very low, greatly reducing its ability to sustain fishing pressure. Maximum size attained is 220 to 270 cm total length (TL) (males) and 300 to 320 cm TL (females). Age at maturity is 6 to 7 years (males) and 9 to 10 years (females). Female k = 0.11, Male k = 0.16 (Goldman 2002).
