    Silvertip Shark, Carcharhinus albimarginatus (Rüppell 1837)

    More Info


    Distribution

    Widespread but patchy distribution in the Indian and Pacific Oceans. Known in northern Australian waters from about Carnarvon (Western Australia) to Bundaberg (Queensland); absent from the Gulf of Carpentaria and the Arafura Sea.

    The Silvertip Shark inhabits continental shelf and offshore waters, around offshore islands and coral reefs, in depths from the surface to 800 m. Adults are wide-ranging, whereas the young prefer shallower waters closer to shore.

    Features

    Body slender, snout long, broadly rounded; eyes large; ridge present between the dorsal fins; first dorsal fin large with a pointed tip, originating above or slightly before the free tips of the pectoral fins; second dorsal fin originating above or slightly behind the anal-fin origin; pectoral fins large, with narrowly rounded or pointed tips; caudal fin with a large upper lobe.

    Size

    To 3 metres in length.

    Colour

    Body grey to greyish-brown with a bronze sheen above, pale below, with an indistinct pale stripe along the sides to above the pectoral fin. First dorsal, pectoral and caudal fins with distinct white tips..

    Biology

    Viviparous, with a yolk sac placenta. Females give birth to 1-11 pups per litter every second year, after a gestation period of 12 months. The young are born at 73-81 cm TL.  (Compagno et al. 2005). This is a large, slow-growing shark, which reaches a maximum size of 300 cm TL (Compagno et al. 2005).  White et al. (2006) report that males mature at 190-200 cm TL and females at ~195 cm TL.

    Fisheries

    Taken as bycatch in longline, gillnet and trawl fisheries throughout its range, and caught in high-seas longline and net fisheries that target tunas.

    Conservation

  • IUCN Red List: Near Threatened
  • EPBC Act: Not Listed
  • Etymology

    Carcharhinus is from the Greek karcharos meaning 'sharpen', and rhinos meaning nose, in reference to the pointed snout. The species name albimarginatus is from the Latin albi meaning 'white' and marginatus meaning enclose or surround with a border - in reference to the distinct white fin margins.
