Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: currently known only from the continental shelf of tropical Australia. Very similar to Carcharhinus limbatus and reliably distinguished only by biochemical studies and vertebral counts (Ref. 9819).

Biology     Glossary (e.g. epibenthic)

Found on the continental shelf from close inshore to about 150 m depth (Ref. 9997). Found throughout the water column but usually near the sea bed during the day and near the surface at night (Ref. 6390). Prefers teleost fishes but also feeds on cephalopods to a lesser degree. Viviparous (Ref. 50449). Forms large aggregations (Ref. 6871). Utilized for its meat and fins (Ref. 6871). The flesh has a relatively high mercury content (Ref. 6871).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous, placental (Ref. 50449). The average litter size is 3, with a range of 1-6, average total length at birth is 60 cm. Pups are born in January after a 10-month gestation period. These sharks breed once each year (Ref. 13440). Distinct pairing with embrace (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00241 - 0.01199), b=3.09 (2.91 - 3.27), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.14; tm=3-4; tmax=12).
Vulnerability (Ref. 59153):  High to very high vulnerability (70 of 100) .
Price category (Ref. 80766):   Medium.
