In the Bahamas, more than 30% of dolphins have shark-bite scars. With a never-before-seen non-toxic gel bite pad and life-sized dolphin decoy, Dr. Mike Heithaus and Dr. Valeria Paz collect bite impressions from three shark species that might be the predators. Bites from bull sharks, tiger sharks and great hammerheads — up to 14 feet long — are compared to scars photographed on dolphins.
Numerous reports of giant great hammerhead sharks, up to twenty feet in length, have put the actual size potential of this species into question. A team of scientists from Florida International University is now on an expedition off the Florida coast to try and find the world’s biggest hammerhead, taking them from the numerous bridges of the Florida Keys to the sharky waters of the Bahamas.
