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);  hemiodon: hemi-, from hemisys (Gr.), half; odon (Gr.), tooth, allusion not explained, perhaps referring to how teeth on upper jaw are serrated basally and smooth distally. (See ETYFish).

Biology     Glossary (e.g. epibenthic)

A little-known shark found on the continental and insular shelves (Ref. 244). Reports from river mouths and rivers are based on old records that need verification (Ref. 9997). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 9997). Viviparous (Ref. 50449). Utilized fresh for human consumption (Ref. 9997).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 25.2 - 29.1, mean 28.3 °C (based on 844 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 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   ±0.58 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Medium.
