Coral Reefs
Learn about the reef systems that form the foundation of life in the Maldives, the coral species you will encounter, and the conservation efforts protecting them from bleaching and climate change.
Nature and Marine Life in the Maldives
Discover a world beneath the waves where coral gardens glow with colour, gentle giants glide through crystal-clear water, and pristine sandbanks stretch to the horizon.
The Maldives is one of the most biodiverse marine environments on Earth. Spread across 26 atolls in the Indian Ocean, the archipelago supports thousands of species of fish, hundreds of coral species, and some of the ocean's most iconic megafauna. Whether you are snorkelling off a house reef or diving a deep channel, the underwater world here is extraordinary.
Above the surface, the Maldives offers its own quiet beauty: shifting sandbanks that appear and disappear with the tides, turquoise lagoons so shallow you can walk across them, and skies full of seabirds. This section is your guide to the nature that makes these islands so special.

Reef Ecosystems
Explore how Maldivian reef ecosystems function as interconnected communities — from coral-algae symbiosis and cleaner fish stations to the food chains that support everything from tiny shrimp to apex predators.
Coral Bleaching
Understand what causes coral bleaching, how rising ocean temperatures have triggered major bleaching events across the Maldives, and what scientists and resorts are doing to help reefs recover.
Giant Clams
Meet the iridescent giant clams that dot Maldivian reefs — learn how they get their vivid colours from symbiotic algae, where to spot them, and why they are important indicators of reef health.
Octopus
Discover the remarkably intelligent reef octopus — a master of camouflage that hides in plain sight on Maldivian reefs. Learn their habits, hunting techniques, and the best times to spot them.
Reef Sharks
Blacktip and whitetip reef sharks patrol the shallows of nearly every Maldivian atoll. Learn to tell them apart, understand their behaviour, and discover the best reefs for close encounters.
Nurse Sharks
The gentle tawny nurse shark is one of the easiest sharks to encounter in the Maldives, often resting on sandy bottoms near harbours and under coral overhangs. Learn where to find them and how to observe them safely.
Moray Eels
From the massive giant moray to the intricately patterned honeycomb moray, these reef dwellers are a highlight of any dive. Discover their fascinating cleaning station behaviour and where to see them up close.
Reef Conservation
Learn about the marine protected areas, nationwide shark fishing ban, coral nursery projects, and community-led programmes that are working to safeguard the Maldives' reefs — and how visitors can help.
Seagrass Meadows
Often overlooked in favour of coral, the seagrass meadows of the Maldives are vital nurseries for juvenile fish, feeding grounds for sea turtles, and powerful carbon sinks that help protect the climate.
Lagoons of the Maldives
The shallow turquoise lagoons enclosed by each atoll are among the most visually stunning features of the Maldives. Discover how they form, what marine life thrives in them, and the best lagoons to visit.
Hammerhead Sharks
The scalloped hammerhead is one of the most sought-after sightings in the Maldives, found schooling at depth off Rasdhoo Atoll and other deep channel sites during early-morning dives.
Eagle Rays
With their diamond-shaped wings and striking spotted patterns, eagle rays are a graceful highlight of channel dives and lagoon encounters across the Maldivian atolls.
Reef Fish
Over a thousand species of reef fish inhabit the Maldives — from vivid butterflyfish and parrotfish to surgeonfish and wrasses. A guide to the families you will see on every snorkel and dive.
Barracuda
Sleek, silver, and lightning-fast, barracuda are a thrilling sight on Maldivian reefs — from solitary great barracuda patrolling drop-offs to mesmerising tornado-like schools of chevron barracuda.
Jackfish
Powerful, fast, and endlessly impressive — giant trevally, bluefin trevally, and bigeye jacks hunt the channels and outer reefs of the Maldives in spectacular schooling formations.
Reef Cleaning Stations
Watch tiny cleaner wrasses and shrimp service fish many times their size at dedicated reef cleaning stations — one of the most fascinating examples of mutualism in the marine world.
Coral Atolls
The 26 natural atolls of the Maldives are ring-shaped coral structures built over millions of years. Discover how they formed, their anatomy of channels and lagoons, and why each atoll is unique.
Coral Restoration
After devastating bleaching events, coral restoration programmes across the Maldives are rebuilding reefs using coral frames, nurseries, and fragment transplantation — and visitors can help.
Marine Protected Areas
From Hanifaru Bay to the nationwide shark sanctuary, the Maldives has established a network of marine protected areas that safeguard its most important reefs, channels, and feeding grounds.
Dive Sites
An overview of the Maldives' world-class dive sites — from the legendary thilas and kandus of North Malé and Ari Atoll to pristine southern channels teeming with pelagic life.
Bioluminescence
When the ocean glows electric blue at night — the science behind bioluminescent plankton, the best islands and seasons to see it, and why the Maldives is one of the best places on Earth for this phenomenon.
Dolphins
Spinner dolphins, bottlenose dolphins, and more — learn about the species found in Maldivian waters, their behaviour, where to see them, and responsible dolphin watching practices.
Birds of the Maldives
Herons stalking the shallows, white terns hovering above the reef, frigate birds soaring overhead — over 180 bird species have been recorded across the atolls, from resident seabirds to migratory waders.
Coconut Palms
The national tree of the Maldives — its ecological role in island stabilisation, its centuries of traditional use for food, rope, and building, and why it defines the Maldivian landscape.
A Fragile Paradise
The Maldives sits at the frontline of climate change. Rising sea temperatures have triggered multiple coral bleaching events, and rising sea levels threaten the low-lying islands themselves. At the same time, the nation has become a leader in marine conservation, establishing protected areas, banning shark fishing across its entire exclusive economic zone, and supporting community-led reef restoration projects.
Understanding the nature of the Maldives is the first step toward protecting it. We encourage every visitor to practise responsible tourism: choose reef-safe sunscreen, do not touch or stand on coral, maintain a respectful distance from marine life, and support operators who follow sustainable guidelines.
