Documentary showing life under the Pacific Ocean and the predatory life of the marlin, sailfish, sea snakes, dolphins and tuna, birds and turtles.

Wildlife film about sperm whales, revealing the secret lives led by these often misunderstood ocean giants.

Scientists all over the world are now learning about the secret lives of sperm whales, the world's largest hunters that spawned the legendy of Moby Dick. Although Mellville painted them as fearsome beasts of the sea, they are actually shy creatures, and cameraman Rick Rosenthal needed patience and persistence to film them at close quarters. They turn out to be efficient hunters with a close family network involving sophisticated and vocal social lives.

A dramatic film about Right Whales, the rarest of all the great whales. There's a race on to save them and even US nuclear submarines are part of the effort. Dramatic footage above and below the water reveals these fascinating giants battling for mates, rearing young, sailing with their tails and meeting other whales, dolphins, seals and sharks. It's called the Right Whale because it used to be the right whale to hunt - big and full of blubber. Today it's baffling biologists who cannot understand why, in spite of total protection, it refuses to recover.

The billfish are the biggest, fastest, and most dangerous gamefish in the sea. All have captured man's imagination like few other creatures, whether it's the graceful sailfish, the menacing swordfish or queen of them all, the marlin, immortalized by Hemingway in 'The Old Man and the Sea'. Marine biologist and film-maker Rick Rosenthal has travelled three oceans in his attempt to capture them all on film, and in doing so has become a passionate champion for these endangered yet little-known ocean giants.
