Carcharhinus limbatus (Müller & Henle, 1839)

Genus: ,

Scientific Name: Carcharhinus limbatus

English Name: Blacktip shark

Creole Name: Nennen pwent

French Name: Requin pointes noires

IUCN Red List Status: Near Threatened (NT)

Description:

Mid-sized stout shark with long pointed snout, colour can vary quite significantly from dove grey through Dark grey to brown-grey on back, white or cream below, conspicuous white band on flanks. Fin tips usually black on pectorals, dorsals and ventral caudal lobe, pelvic and sometimes the anal fin. Large individuals may have much less pronounced or even lack black fin tips.

Fins: D1 large, falcate (trailing edge curving anteriorly from fin apex) with black tip and/or black edge on narrowly round apex. Origin above pectoral fin insertion to near the pectoral rear free tip. D2 relatively high with black tip.  Origin over or slightly anterior to anal fin. No interdorsal ridge. Pectorals large, falcate with narrowly rounded to pointed black tips. Pelvic fins with black tip. In Seychelles C. limbatus often displays a dark spot towards the end of the pelvic fin rather than a black tip. Anal plain or black-tipped. Caudal fin dorsal lobe black-edged, ventral lobe black-tipped.

Head: Long pointed snout, small circular eyes, long gill slits, anterior nasal flaps short, triangular pointed lobes. Upper labial furrows short and inconspicuous.


Size:

Born 38-72cm TL. Mature: Male 135-180cm TL, Female 120-190cm, Maximum 255cm TL.


Habitat and Ecology:

Viviparous 1-10 pups per litter (typically 4-7) after 10-12 month gestation period. Insular and continental shelves and adjacent waters. Commonly occurs in loose aggregations. Eats teleosts, cephalopods and crustaceans.


Fishery Status:

This species is not protected. It is however illegal to fish for sharks with nets (Fisheries Act, Reg 16.c). It is subject to hook and line, short anchored long line and illegal net fishing. Juveniles and sub-adults are a common component of the artisanal catch. Adults are also caught but much less often.


Notes:

Differentiation from C. brevipinna can be problematic due to variations in colouration of both species. Key distinguishing characteristics are the respective shapes of the D1 fin, the short pectoral fins and the long upper labial furrow of C. brevipinna.

The Creole name “nennen pwent” is also applied to C. brevipinna and C. sorrah as in general the fishers do not distinguish between the three species.
