They are abundant on the tropical coral reefs of the Indian and Pacific Oceans, preferring shallow coastal waters. Most blacktip sharks are found on reef ledges and sandy floors, although they are also known to enter brackish and fresh water. It usually reaches a length of 1.6 metres.

Fun facts

  • It lives in water so shallow that it often swims with its dorsal fin and part of its back out, an iconic image of the coral lagoons of the Indo-Pacific.
  • It is extraordinarily faithful to its territory: tagging studies show individuals staying for years on the same stretch of reef, of barely a few square kilometres.
  • It has been documented forming preferred social associations: some individuals repeatedly seek each other out and swim together for years, a social behaviour once thought not to exist in sharks.
