Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (Requiem sharks)
Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus , an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin. ( See ETYFish ) ;   tilstoni: In honor of Richard Tilston, naturalist-surgeon at Port Essignton, Northern Territory, near where holotype was collected in the 1840s. ( See ETYFish ) .
More on author: Whitley .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; brackish; pelagic-neritic; depth range 0 - 150 m (Ref. 6871 ). Tropical; 10°S - 28°S

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 ).

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 115 - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 9997 ); max. published weight: 52.0 kg (Ref. 6390 ); max. reported age: 12 years (Ref. 6390 )

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 0. Back dark grey, ashy blue or dusky bronze; belly white or yellowish white; a dark band extending rearward along each side to about over origin of pelvic fin; tips of pelvic fins with a persistent black spot (Ref. 9997 ).

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 based on models

Preferred temperature (Ref. 123201 ): 26 - 28.7, mean 27.7 °C (based on 424 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00479 (0.00221 - 0.01036), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.2   ±0.6 se; based on diet studies. Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (K=0.14; tm=3-4; tmax=12). Fishing Vulnerability (Ref. 59153 ):  High to very high vulnerability (70 of 100). Price category (Ref. 80766 ):   Medium .
