Thresher Shark

We’re highlighting one of the ocean’s most mysterious and elegant predators — the Thresher Shark. Known for their extraordinarily long tails, these sharks use them to herd and stun fish, a hunting technique that is both efficient and mesmerizing to watch.

Distribution and Habitat

Thresher Sharks are found in tropical and temperate oceans worldwide, including the Indian, Pacific, and Atlantic Oceans. In the Maldives, they are frequently spotted in Fuvahmulah, a hotspot for divers seeking these incredible pelagics. Excitingly, they are now also being seen near Guraidhoo, giving our dive groups an extraordinary chance to encounter them in our local waters.

Physical Characteristics

Length: Can reach up to 6 meters (20 feet), with tails as long as their bodies.
Body: Sleek and streamlined, perfect for open-water hunting.
Tail: Used like a whip to herd fish into tight schools before striking.

Behavior and Diet

Thresher Sharks are mostly solitary, occasionally seen in small groups. They hunt primarily at dawn and dusk, feeding on small schooling fish and squid. Their graceful movements make them a favorite subject for underwater photographers.

Reproduction

Thresher Sharks are ovoviviparous, meaning the embryos develop inside eggs that remain in the mother until they hatch. Females give birth to 2–4 pups after a gestation period of around 9 months. This low reproductive rate contributes to their vulnerable conservation status, making each sighting even more special.

Conservation

These sharks are considered vulnerable due to fishing pressure and habitat loss. Sightings off Guraidhoo remind us of the importance of protecting these incredible predators and the ecosystems they depend on.

Fun Facts

Their tails, sometimes as long as their body, are not just for show — Thresher Sharks use them like a whip to herd and stun prey, a hunting technique unique among sharks.
They can leap out of the water when hunting — a behavior known as breaching.
Despite their size, they are surprisingly shy and elusive, often avoiding boats and humans.

DIVE WITH THRESHER SHARKS

In Guraidhoo, spotting a Thresher Shark is rare and unforgettable, showcasing the richness of our marine environment. Alongside Fuvahmulah, these sightings are a true highlight for divers and marine enthusiasts, offering a vivid reminder of the wonders that await beneath the waves.
