Equipped with a long, narrow, tooth-studded snout, the Saw Shark uses its saw-like nose to slash at schools of fish, incapacitating or killing them before eating.

Beyond its unique hunting tool, this shark’s snout is also sensitive to electric fields, helping it detect prey on the sandy ocean floor.

Predominantly found in the waters off Australia, Japan, and South Africa, these sharks prefer the ocean’s depths, typically between 130 and 3,000 feet (40 to 900 meters).

5. Basking Shark

Wobbegongs, or carpet sharks, feature a flat body and a patterned appearance that allows them to blend perfectly with the ocean floor.

Their name, meaning “shaggy beard” in an Australian Aboriginal language, refers to the fringed barbels around their mouth, which assist in camouflage and sensing prey. Wobbegongs are ambush predators, lying in wait for unsuspecting fish and invertebrates to pass by before striking.

8. Whale Shark

Despite its immense size, the Whale Shark, reaching up to 62 feet (19 meters) in length, feeds primarily on plankton, which it filters through its vast mouth.

These gentle behemoths are known for their docile nature and are a popular attraction for divers and snorkelers in regions where they aggregate to feed.

The distinctive pattern of white spots and stripes on their dark skin is unique to each individual, similar to human fingerprints.

9. Megamouth Shark

One of the rarest and least understood shark species, the Megamouth Shark, has a massive head and mouth, which it uses to filter feed plankton and jellyfish.

Since its discovery in 1976 (by a U.S. Navy ship in the waters of O’ahu ⁵), only a handful of specimens have been observed, making each sighting a significant event for marine biologists.

This deep-water species is believed to migrate vertically daily, staying in deep waters during the day and moving closer to the surface at night to feed.

10. Thresher Shark

Thresher Sharks are notable for their long, scythe-like tails, which can be as long as the rest of their body. They use these unique tails to slap and stun prey, making them easier to catch. Threshers are highly migratory and found in both coastal and open oceans.

Their deep dives and dramatic breaches are a spectacle, showcasing their athletic prowess.

11. Leopard Shark

The Leopard Shark, with its striking leopard-like spots and bands, is a coastal species found in the Pacific Ocean, from Oregon to the Gulf of California. These bottom dwellers prefer sandy or muddy flats and rocky areas, where they feed on crustaceans, worms, and small fish.

Despite their fierce name, Leopard Sharks are small, typically around 4 to 5 feet (1.2 to 1.5 meters) in length, and pose no threat to humans.

12. Horn Shark
