What to know about silvertip sharks
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
The silvertip shark (Carcharhinus albimarginatus) is a large requiem shark with a fragmented distribution across the tropical Indian and Pacific Oceans. It is often encountered around offshore islands and coral reefs and can dive to depths of about 800 m (2,600 ft). The species attains a maximum length of about 3 m (10 ft) and is bulkier than the grey reef shark. Silvertip sharks are apex predators that feed on a wide variety of bony fishes, eagle rays, smaller sharks, and cephalopods. They are viviparous; females give birth to one to 11 pups in the summer. Silvertip sharks are regarded as potentially dangerous to humans and often approach divers closely. The species is taken by commercial fisheries for meat, fins, skin, cartilage, and jaws and teeth, which has led to local population declines or extirpations.
Commonly cited pressures include Commercial fishing.
Often encountered around offshore islands and coral reefs; known to dive to depths of about 800 m (2,600 ft).
