Havelock Island sits at the crossroads of the Andaman Sea and the Bay of Bengal, creating a unique marine environment that attracts an astonishing variety of sea life. Whether you're on a beginner shore dive or an advanced deep dive, the waters around Havelock never fail to deliver extraordinary encounters. Here are five species that make diving here truly unforgettable.
1. Green & Hawksbill Sea Turtles
Sea turtles are perhaps the most iconic marine creatures you'll encounter in Havelock. Both green turtles and hawksbill turtles are commonly spotted at almost every dive site around the island. These gentle, ancient creatures glide through the water with remarkable grace, and they're surprisingly comfortable around divers. At sites like Turtle Beach and Nemo Reef, it's not uncommon to see multiple turtles on a single dive, munching on sponges and coral or simply cruising through the blue.
2. Manta Rays
Spotting a manta ray is one of diving's ultimate bucket-list moments, and Havelock delivers. These majestic creatures, with wingspans reaching up to 5 meters, visit the deeper dive sites around the island between December and April. Dixson's Pinnacle and Johnny's Gorge are prime manta territory. Watching a manta ray swoop past you in the blue, completely silent, is a feeling that stays with you forever. They often circle back for a second look at divers, seemingly as curious about us as we are about them.
3. Reef Sharks
Blacktip and whitetip reef sharks are regular visitors at Havelock's deeper dive sites. Despite their fearsome reputation (mostly thanks to Hollywood), reef sharks are shy, elegant creatures that pose no danger to divers. They typically range from 1 to 1.5 meters in length and are often seen patrolling the reef edges or resting on sandy bottoms. Sites like The Wall and Jackson's Bar offer consistent shark sightings, especially in the early morning hours.
4. Clownfish & Anemone Gardens
Thanks to a certain animated movie, clownfish are probably the most requested species among beginner divers. Havelock doesn't disappoint — Nemo Reef is named precisely because of its extraordinary concentration of anemone gardens hosting multiple species of clownfish. Watching these tiny, feisty fish dart in and out of their anemone homes is endlessly entertaining. Each anemone hosts a family with a strict hierarchy, and the fish will even come right up to your mask to investigate.
5. Whale Sharks
The holy grail of Andaman diving. Whale sharks — the world's largest fish, reaching lengths of over 12 meters — make seasonal appearances in Andaman waters, typically between February and May. While sightings can't be guaranteed, divers at Havelock have reported encounters at sites like Minerva Ledge and in the open waters between islands. Swimming alongside a whale shark is one of the most humbling experiences nature can offer. Despite their enormous size, they're gentle filter feeders that glide through the water with surprising delicacy.
Every dive in Havelock tells a different story. One day you're eye to eye with a curious sea turtle, the next you're watching a manta ray dance in the blue. That's the magic of these waters.
When to See What
- Sea Turtles: Year-round, virtually every dive
- Manta Rays: December to April at deeper sites
- Reef Sharks: Year-round, best at dawn dives
- Clownfish: Year-round at Nemo Reef and shallow sites
- Whale Sharks: February to May, rare but spectacular
The marine biodiversity of Havelock extends far beyond these five species. On any given dive, you might also encounter eagle rays, barracuda schools, moray eels, octopuses, cuttlefish, nudibranch, and hundreds of species of tropical reef fish. Each dive site has its own character and resident creatures, making every descent a new adventure.
