Grey Reef Sharks are easily identified by their streamlined grey bodies, often with a slightly lighter underside. Look for the prominent black tips on their dorsal fin, pectoral fins, pelvic fins, and especially the lower lobe of their caudal fin (tail). Their snout is moderately long and rounded, and they have relatively large eyes. When threatened, they may exhibit an exaggerated, jerky swimming motion, arching their back and dropping their pectoral fins – a clear sign to back off.
The Grey Reef Shark is listed as vulnerable by the IUCN. When diving, please observe from a distance, avoid touching or feeding, and report any sightings to local marine research organisations.

Carcharhinidae
The Grey Reef Shark (Carcharhinus amblyrhynchos) is a quintessential reef shark, a common sight for divers exploring tropical waters. With a sleek, torpedo-shaped body and distinctive dark tips on its fins, this shark adds a touch of adrenaline to any dive. Often seen patrolling reef edges and drop-offs, they are a crucial part of the reef ecosystem. Encounters typically involve observing them cruising gracefully in the distance, or perhaps forming small aggregations in current-swept areas. Their presence is a sign of a healthy reef system, and witnessing their effortless movement is a privilege for any underwater explorer. While generally not aggressive, Grey Reef Sharks are known for their 'threat display' if they feel cornered or threatened. This involves an exaggerated swimming motion and arching of the back, a clear signal to give them space. This behaviour is more commonly observed during feeding frenzies or in areas with limited escape routes. Most encounters are peaceful, offering divers a fantastic opportunity to observe these apex predators in their natural habitat. Remember to respect their space and enjoy the view!
