Scalloped Hammerhead Shark

The scalloped hammerhead shark is among 10 related species of hammerhead sharks found in tropical and temperate waters worldwide. The large flattened extensions of its head give this shark a hydroplanelike lift and enable it to make sharper turns than most other sharks. Because its eyes and nostrils are placed at the ends of its head extension, the hammerhead has better ability to track its prey. So keen is its sense of smell that the scalloped hammerhead can detect even a tiny amount (one part per million) of blood in sea water. Though some of the small hammerhead species are not considered dangerous to humans, the scalloped hammerhead most certainly is.
