The Goliath Grouper - The Goliath Grouper is one of the largest bony fish in the world, and this made it the target of intense fishing efforts for many years. After nearly becoming extinct, laws to protect these fish enacted in 1990 are finally starting to pay off. Jonathan visits a shipwreck in Florida where Goliath Groupers gather to spawn every year, and meets dozens of these massive animals! The Great Barrier Reef - Jonathan visits the largest reef system in the world: the famous Great Barrier Reef of Australia. In addition to going diving, he visits the reef as non-divers often do-by submarine, helicopter and even in a bubble helmet! Along the way he meets some amazing animals such as a friendly sea turtle and a giant wrasse! Color and Camouflage - In this fascinating science segment, Jonathan explores the myriad ways that animals in the ocean use color and camouflage to protect themselves, hunt and find a mate. The frogfish shows off how it uses camouflage to be nature's perfect ambush predator!
