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);  sorrah: Tamil (Indian subcontinent) word for shark [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

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

Marine; brackish; reef-associated; depth range 0 - 140 m (Ref. 30573), usually 1 - 73 m (Ref. 90102). Tropical; 31°N - 31°S

Also from Vanikolo Island (Santa Cruz Islands) and the Solomon Islands. Possibly occurring in the Gulf of Aden, Gulf of Oman and Sri Lanka (Ref. 9997).

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A small, spindle-shaped shark with a long, rounded snout, large circular eyes, and oblique-cusped serrated teeth; 2nd dorsal fin very low; interdorsal ridge present (Ref. 5578). 2nd dorsal, pectorals and lower caudal lobe with dark tips; 1st dorsal with thin but conspicuous dark tip; pelvic fins and upper caudal lobe plain (Ref. 5485). Grey or grey-brown above, white below with a golden-brown sheen on the area between eyes and gill slits (in fresh specimens); pectorals, second dorsal, and lower caudal fin lobe with conspicuous black tips, first dorsal and upper caudal fin lobe with black edging (Ref. 9997). A dark band on flank extending rearwards to pelvic fins (Ref. 9997).

Biology     Glossary (e.g. epibenthic)

Found on the continental and insular shelves, primarily near reefs (Ref. 244). Sometimes in offshore waters (Ref. 30573). Live near the seabed during the day and near the surface at night (Ref. 6390). Feeds on bony fishes (Ref. 68964). Shark movements often short (50 km) but may be more than 1,000 km (Ref. 6390). Prefers teleost fishes but also feeds on cephalopods and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Regularly caught by local artisanal and small-scale commercial fisheries where it occurs (Ref. 244). Utilized as a food fish; fins used in the oriental shark fin trade, liver for vitamin oil, and offal for fishmeal (Ref. 9997).

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

Viviparous, with a yolk-sac placenta (Ref. 244). Pups, average 3, range 1-8, are produced in January after a 10-month gestation period. Average length at birth is 50 cm TL. Length increases by about 25 cm during the first year. These sharks breed once each year (Ref. 13440). Distinct pairing with embrace (Ref. 205).
