Physical Characteristics

Generally, the hammerhead is more streamlined than other sharks allowing for tight maneuverability. The distinctive head shape allows the hammerhead to see 360 degrees around it.

What Does A Hammerhead Shark Eat?

Hammerheads eat a variety of fish but they seem to particularly like stingrays and it is possible that their hammer-shaped head is actually an adaptation to pin down stingrays. Hammerheads have been observed diving down on stingrays, pinning them and pivoting to take bites from the pectoral fins.

Claim to Fame

Hammerheads have uniquely shaped heads. Scientist suggest this adaptation may have occurred for several reason such as heightening the sharks ability to detect electrical impulses and for maneuvering. Recently scientists have suggested that their head may be specially adapted for pinning rays down.to the sea floor.

Shark Attacks

Three species of hammerheads are potentially dangerous to humans including: the great hammerhead, the scalloped and the scoop. The great hammerhead is particularly seen as a threat because of its curiosity and willingness to inspect a human being. Hammerhead sharks are typically not dangerous and no fatal incidents have been recorded.
