Inside Nature’s Giants – The Sperm Whale (Channel 4 HD Documentary)

The BAFTA winning team battle through the night against a rising tide to explore the mysteries of the largest predator on Earth: the sperm whale. Veterinary scientist Mark Evans and comparative anatomist Joy Reidenberg remove and examine one of its vestigial upper teeth and dissect the whale’s enormous organs to reveal the secrets of this 45 foot deep sea giant, which stranded and died on Pegwell Bay in Kent. Despite their enormous size, we know very little about sperm whales because their lives are normally hidden deep beneath the waves. The programme reveals how they can survive diving down thousands of metres for over an hour on one gulp of air in conditions that would freeze our blood and crush our bones. As the team go inside the whale, biologist Simon Watt tracks whales in the Azores with a modern day Jonah, Malcolm Clarke, who gives him a sniff of his prized whale rectum samples and shows him the huge number of squid beaks in a whale’s stomach. Meanwhile, joined by diggers, trucks and a reluctant local tree surgeon, the team on the beach discover how sperm whales use the largest nose in the animal kingdom to hunt giant squid in the dark.
The award winning series that gets under the skin of the largest animals on the planet. Inside Nature’s Giants dissects these animals to uncover their evolutionary secrets. Most wildlife documentaries tell you how an animal behaves, but by dissecting an animal and studying its anatomy we can see how animals really work. Experts in comparative anatomy, evolution and behaviour will put some of the most popular and enigmatic large animals under the knife. Veterinary scientist Mark Evans will interpret their findings, biologist Simon Watts tests the animals physiology and Richard Dawkins traces back the animals place on the tree of life.
