Joe Romeiro has been fascinated with sharks since he was just five years old. He has since devoted his life to the conservation and documentation of these dangerous predators. With his partner Bill Fisher, the duo capture unbelievable close-up shots of sharks, including the hammerheads pictured below. Joe acts as “shark whisperer,” feeding and petting the 20ft-long, half-ton great hammerheads as if they were harmless puppies while Bill photographs the action.
