Bonnethead Shark

Bonnethead Sharks are abundant in nearshore Florida waters. This species is the smallest of the hammerhead sharks. They are harmless to people, who often use the meat as crab bait (Florida Fish and Wildlife Conservation Commission). The beach at the Merritt Island was full of fishermen and beach people. These sharks are said to be good sport fish, but the fishermen appeared to leaving their catch to die on the sand.

The purpose of the peculiar-shaped head of this shark is not fully understood. Hypotheses include enhanced reception of prey electrical impulses, enhanced maneuvering while swimming, and prey manipulation (these sharks sometimes use their heads to pin down stingrays). Of the ten species of hammerheads worldwide, one three are known to have attacked humans.
