Eastern Indian Ocean: endemic to southern Australia, from Western Australia through Bass Strait to Tasmania and northern New South Wales. Possibly extends northward to southern Queensland and Shark Bay in Western Australia. Confused with another undescribed species whose southern distribution extends to Dampier (20°40'S) (possibly Shark Bay) in the west and Bowen (20°S) (possibly Coffs Harbor) in the east. There is a single stock of gummy sharks in the area, however, regional stock differences might still exist.

Biologia     Glossário (ex. epibenthic)

An inshore and offshore shark found from intertidal waters (Ref. 13563) to a depth of 350 m. Feeds on crustaceans, marine worms and small fishes (Ref. 13563), also cephalopods. Forms schools by sex and size . Ovoviviparous (Ref. 50449). Newborn and juvenile gummy sharks are found in many areas across southern Australia, but no well-defined nursery areas have been identified. These sharks are capable of long migrations, females traveling longer distances than males (Ref. 6390). Utilized fresh for human consumption (Ref. 6871). Maximum length data for female species is taken from Ref. 6390.

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Ovoviviparous but aplacental, with 1 to 38 pups. Embryos feed solely on yolk (Ref. 50449). Gestation period ranges from 11-12 months. Newborn and juvenile gummy sharks aggregate in many areas across southern Australia but it is not known whether they inhabit defined shallow-water nursery areas. Ovulation takes place in Oct.-Dec. or Nov.- Feb. (WA). Parturition is complete by the following Dec. (Ref. 6390). The sharks are born at 30-35 cm (Ref. 6871).
