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); amblyrhynchoides: -oides, Greek suffix meaning like, resembling, having the form of: similar to C. amblyrhynchos, to which it had previously been identified. (See ETYFish).

Dorsal spines (total): 0; Anal spines: 0. Grey or grey-brown on dorsal surface, white or cream below, with a conspicuous band of white on sides from pelvic fins to first dorsal fin; pectoral, dorsal and pelvic fins, and ventral lobe of caudal fin black or dusky-tipped, sometimes inconspicuously (Ref. 9997).
A little-known inshore, coastal pelagic species (Ref. 9997). Feeds mainly on fishes, also takes crustaceans and cephalopods (Ref. 6871). Viviparous (Ref. 50449). Probably taken in fisheries where it occurs (Ref. 9997). Utilized fresh and dried salted for human consumption; fins used in the oriental shark fin trade; liver oil processed for vitamins (Ref. 9997).
Viviparous, placental (Ref. 50449). 3 in a litter (Ref. 6871); 2-8 pups per litter (Ref.58048). Gestation period of 9-10 months (Ref. 6871). Size at birth 52 to 55 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 24.9 - 29, mean 28 °C (based on 974 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.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Fec=3).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
