Broadcast (2010) The giant squid was long thought to be the stuff of legend. It was only in the late 19th century that it was first officially recorded by scientists, after one leviathan squid washed up on a beach in New Zealand. Related to slugs and snails, this monster from the deep, along with its cousin the colossal squid, is the largest invertebrate in the world. It has never been filmed in its natural habitat hundreds of metres down, but occasionally specimens are brought to the surface by deep sea trawlers. Joy Reidenberg and Mark Evans fly out to New Zealand to join a team of experts and dissect a rare specimen of a giant squid and a bizarre octopus that inhabits the 'midnight zone' over a kilometre deep, where no light reaches at that depth.
From the moment they set eyes on these cephalopods, the dissection team is fascinated by the alien anatomy of these strange cousins. The team discover that the giant squid has teeth on its tentacles and tongue, a throat that dives through the middle of its brain, and three hearts that power blue blood through a muscle filled jet propulsion cloak. They investigate how octopus and squid are masters of disguise and survive underwater warfare using camouflage, ink jets and spectacular light shows. They piece together the puzzle of how the giant squid hunts, how it jets through the water, how its quick fire beak pulverises food and why it has such enormous eyes. They also discover the brutal truth about giant squid sex.
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.

Broadcast (2010) The experts travel to South Africa to dissect a 900kg, 15 foot long great white shark. Comparative anatomist Joy Reidenberg uncovers the shark's incredible array of senses, including the ability to detect the electro-magnetic field given off by other creatures. Veterinary scientist Mark Evans investigates the origins of the shark's infamous killing bite and, out at sea, a bite force test on a live great white shows just how powerful those jaws really are. Evolutionary biologist Richard Dawkins explains how sharks' teeth and jaws evolved from their outer skin and gill arches. The team ask whether the sharks reputation as a man killer is deserved.

Broadcast (2009) Creationists question how this extraordinary creature could have evolved such a long neck, but for evolutionary biologist Professor Richard Dawkins the anatomy of the world's tallest animal provides some of the best arguments in favour of Darwinian natural selection. For example, one nerve takes a huge detour up and down the long neck, from the voice box to the brain via the chest, hardly the work of an `Intelligent Designer'. And despite its length, the neck still only has seven vertebrae the same number as almost all mammals, from mice to humans and whales. The giraffe has the highest blood pressure of any animal; with a heart not much bigger than our own it must pump blood at high pressure around a towering body. It has evolved thick skin that acts as a natural 'G-suit' and a complex circulation system to avoid passing out when raising and lowering its head. Bologist Simon Watt observes them in the field as they eat, forage and fight to reproduce.

Broadcast (2009) Veterinary scientist Mark Evans joins experts in anatomy, evolution and behaviour in a bid to get under the skin of the crocodile. Evolutionary biologist Professor Richard Dawkins explains how little the crocodile has changed since the age of the dinosaurs. The team uncovers the crocodile's incredible jaw muscles, as biologist Simon Watt travels to Florida to test the huge strength of the massive reptile's bite, the pressure of the crocodile's bite is more than 5,000 pounds per square inch. But while crocodiles' spiked teeth are excellent for gripping prey as they plunge into a death roll, they are useless for chewing. So how do these animals manage to digest large chunks of raw meat and bone? As the experts dissect the digestive system and inspect the stomach contents for clues, they reveal the bizarre plumbing between the heart and the stomach that might provide the key to this puzzle. The team also solve the mystery of this crocodile's premature death.

Broadcast (2009) The team dissect a 65 foot, 60 ton fin whale, second only in size to its 'cousin' the blue whale. The whale died after being stranded off the coast of Ireland. It's a race against time as whale anatomist Joy Reidenberg flies in from New York before the animal's decomposition causes it to explode on the beach. Veterinary scientist Mark Evans helps investigate why the animal died and explores its extraordinary anatomy. Using whale size machinery, Joy and the team set to work amidst gale force winds, driving rain, blood and freezing conditions. Advancing tides threaten to engulf the whale as the team struggles to complete the dissection .
Beneath the blubber, the whale's unique anatomy holds vital clues to its evolution. Using a combination of dissection and computer graphics, the programme discovers an animal whose closest living relative is the hippo. Meanwhile, evolutionary biologist Richard Dawkins explains why the whale's ancestors may have taken to the water and the evolutionary problems that had to be overcome to transform a land based mammal into an animal that is found in all the world's major oceans, and in waters ranging from the polar to the tropical.
