They give birth to 6 to 14 young. Adults range in size from 5' to 7' with a maximum of 10'. The sharks we see range from 2' to 3'. Their first dorsal fin is relatively small, rounded and starts behind the pectoral fins. Their second dorsal fin is small and has a long trailing edge.
Divers occasionally see scalloped hammerheads swimming over the reefs or along the walls.
The unusual video at right was shot during one of our shark dives. Adults range from 5' to 9', with a maximum length of 14'. The front edge of the hammer has a scalloped look. The inside tip of the pectoral fins are dark. Whale sharks are seen only in winter.
