- 🛡️ Endangered (IUCN)
The grey reef shark patrols reef walls and passes, often in groups. Plain grey with a black edge on the back of its tail, it is heftier than the blacktip reef shark. When it feels threatened it may adopt a warning posture, back arched and pectoral fins lowered. The big passes of Rangiroa and Fakarava are famous for their walls of grey reef sharks.
