Frequently Asked Questions
The most commonly encountered marine life includes grey reef sharks, white tip reef sharks, various tropical fish families (angelfish, butterflyfish, parrotfish), sea turtles, eagle rays, and numerous coral species. These can be seen year-round at most dive sites throughout the archipelago.
Manta rays are best encountered during the southwest monsoon (May-November) when plankton-rich waters attract them to cleaning stations. Whale sharks are most commonly seen from August to November, particularly in Ari Atoll during plankton blooms.
The Maldives has very few dangerous marine animals. Sharks are generally harmless to humans, and attacks are extremely rare. The main concerns are stonefish (well-camouflaged), sea urchins, and some jellyfish. Following proper diving guidelines and not touching marine life ensures safe encounters.
Many marine species can be observed while snorkeling, especially in shallow lagoons and house reefs. However, scuba diving provides access to deeper sites with larger marine life like sharks, mantas, and whale sharks. Both activities offer excellent marine life encounters.
Practice responsible diving and snorkeling by not touching marine life, maintaining proper buoyancy to avoid coral damage, using reef-safe sunscreen, not feeding fish, and following local marine park regulations. Support conservation efforts and choose operators committed to sustainable tourism practices.
Essential items include an underwater camera or waterproof housing, marine life identification guide or app, underwater writing slate for notes, reef-safe sunscreen, and quality mask and snorkel. For diving, consider bringing your own dive computer and underwater light for better marine life observation.
