Fantastic Wildlife of the Cook Islands

The Cook Islands are a holidaymaker’s paradise. They are famous for stunning beaches, breathtaking scenery, world-class resorts, and rich culture. What many visitors don’t realise is that these islands are also home to incredible wildlife, including species found nowhere else in the world.

We’ve highlighted some of our favourites so you know what to look forward to on your dream Cook Islands getaway.

1. Black Lip Pearl Oyster

First on our list is the Black Lip Pearl Oyster, best known for producing the world’s most prized black pearls. These gems drive an important industry in the Cook Islands, especially in Manihiki. You’ll see them crafted into earrings, necklaces, and bracelets in local markets and jewellery stores. Exotic and elegant, they make perfect gifts to take home.

2. Coconut Crabs

Coconut Crabs became famous after appearing on Survivor: Cook Islands in 2006. They are the largest land-living crabs in the world, growing up to 40 cm long and weighing over 4 kg. Known as “robber crabs,” they feed on fruit, nuts, and seeds. Though sightings are less common now, you might still spot one on the outer islands. If you do, keep your camera ready.

3. Hawksbill Turtles

The Hawksbill Turtle is one of several turtle species in the Cook Islands, alongside Green and Loggerhead Turtles. With their pointed beak and beautifully patterned shells, Hawksbills are a favourite for divers and snorkelers. Their shells can even glow under certain light due to biofluorescence. You’ll often find them swimming gracefully around coral reefs.

4. Moko (Gecko)

The Moko, a small gecko, may not be glamorous, but it is iconic. Common across Rarotonga, Mokos are easy to recognise by their shrill call. Thanks to special toe pads, they can climb trees, walls, and even ceilings. Their quick movements and camouflage make them tricky to spot, but you’re almost guaranteed to see one during your stay.

5. Humpback Whales

Visit between June and September, and you might witness the migration of Humpback Whales. These giants travel through Cook Islands waters to feed and play near deep reef trenches. Watching them breach against a glowing sunset is one of the most memorable sights you’ll ever experience.
