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.
Athletic, playful and loving, our canine companions are extraordinary animals. From acrobatics to breathtaking stunts, skateboarding to riding a scooter, and rope jumping to surfing, this special celebrates amazing dogs and their dedicated owners, and reveals how some underdogs tuned from rejected puppy to thriving star.
