Silvertip shark (Carcharhinus albimarginatus)

Appearance and identification

Silvertip sharks are robust, streamlined animals with a rounded snout and relatively large dorsal fin. Adult length typically ranges around two to two and a half metres, and individuals rarely approach three metres. Key identification traits include the conspicuous white tips or margins on the pectoral, dorsal, pelvic and caudal fins; for this marking see white fin tips. When comparing to other requiem sharks, the silvertip often appears darker overall with a silvery sheen.

Habitat and distribution

This species is native to tropical and warm temperate waters across the Indian Ocean and the Pacific Ocean. It is commonly encountered around islands, coral reefs, and continental shelves, where it uses both shallow coastal areas and deeper offshore waters. For regional references consult general resources on the Indian Ocean and the Pacific Ocean ranges.

Behavior, diet and reproduction

Silvertip sharks are active predators that feed on bony fish, cephalopods and other marine vertebrates. Like many requiem sharks they are viviparous, giving birth to live young after internal gestation supported by a placental connection. Observers often describe them as curious and bold around divers; while not the most aggressive species, they should be treated with caution as with any large shark.

Conservation and human interactions

Populations of silvertip sharks are affected by targeted fisheries and bycatch in commercial and artisanal gear. Their meat, fins and liver products can be removed for local use or trade. Conservation assessments and management measures vary by region; more information on general shark biology and human interactions can be found via broader shark resources about sharks.

Notable facts and identification checklist

• Scientific name: Carcharhinus albimarginatus (species reference).
• Distinctive white margins on multiple fins (white tips).
• Found across the Indian Ocean and Pacific Ocean regions.
• Member of the requiem shark group (Carcharhinidae).

The silvertip shark remains a notable species for divers and researchers due to its striking appearance and role as a mid‑ to top‑level predator in reef and nearshore ecosystems. Continued monitoring of population trends and fishing impacts is important for its long‑term conservation.
