Hitch a ride on the ocean's superhighways as giants of the deep ride the currents in perpetual search of their next meal. Get uncomfortably close to the world's largest animal, the massive blue whale, with a heart as large as a small car, a tongue as heavy as an elephant and a tail as wide as an airplane wing. Witness the grace and precision of a great white shark attack . Swim with yellowfin tuna and jump through the waters with spinning dolphins.
