Scientific name: Sphyrna lewini

Scalloped Hammerheads live on sandy seabeds near the coast in northern and southern Australia. They can found down to depths of 130 m.

Scalloped Hammerheads eat bony fishes, other sharks, octopuses, squids and cuttlefish.

Their teeth are small, slightly serrated and piercing. The upper teeth are narrow and triangular. The lower teeth are more slender.

Scalloped Hammerheads catch their food by using electrical receptors in their skin to find animals buried in the sand. They can do this because all animals give off very small electrical signals.

Scalloped Hammerheads give birth to as many as 23 live young at a time.

Scalloped Hammerheads can grow up to 2 m long. Scalloped Hammerheads are not usually dangerous unless they are harassed. Sometimes they display threat postures when approached by divers.

The amazing hammer-shaped head of the Hammerhead sharks allows them to smell, see and use their electro-sensory equipment over a large area. The winged shape of the head also allows the shark to manoeuvre very quickly as it twists and turns after speedy prey.
