A team of experts dissect the largest animals on the planet to uncover their evolutionary secrets in INSIDE NATURE'S GIANTS. In each episode, veterinary scientist Mark Evans, comparative anatomist Joy Reidenberg, biologist Simon Watt and evolutionary biologist Richard Dawkins explore the anatomy of a distinct giant predator to reveal how it works.

"Monster Python" - In Florida’s Everglades, Mark Evans and Dr. Joy Reidenberg meet “python hunters” who are attempting to control the python population (approximately 100,000) through a cull. They join reptile expert Jeanette Wyneken to dissect two pythons: a nine-foot male and a 14-foot female.

The program explores the science of slithering, as well as the development of “infra-red goggles” that let the snakes hunt warm-blooded prey in the dark and a flexible jaw that allows them to stretch their mouths around huge prey, including alligators.

The scientists make an amazing discovery in the female: ovaries bulging with 40 egg follicles ready to be fertilized. Richard Dawkins describes how snakes evolved from four-legged lizard-like ancestors, and biologist Simon Watt finds out what it feels like to be crushed by a real-life python.

This series originally aired in 2011.

Full Episode: INSIDE NATURE'S GIANTS: Big Cats

In this episode of INSIDE NATURE'S GIANTS, the experts dissect a lion and a tiger. From the outside, the two look very different, but once their skins are removed, even the experts find it hard to tell them apart. Biologist Simon Watt comes face to face with a liger — a cross between a lion and a tiger — proof of the two species’ similarity.

Full Episode: INSIDE NATURE'S GIANTS: Great White Shark

In this episode of INSIDE NATURE'S GIANTS, the experts travel to South Africa to dissect a 15-foot-long great white shark. Comparative anatomist Dr. Joy Reidenberg uncovers the amazing array of senses the shark possesses, including the ability to detect the electro-magnetic field given off by other creatures.

Full Episode: INSIDE NATURE'S GIANTS: Giant Squid

In this episode of INSIDE NATURE’S GIANTS, the team travels to New Zealand to examine one of the biggest yet most mysterious animals on Earth — the giant squid. Delving into its three hearts, razor sharp beak, tooth-covered tentacles and bizarre reproductive system, the team explores the anatomy of a deep-sea alien that’s never been observed in the wild.


In this episode of INSIDE NATURE'S GIANTS, Mark Evans and Dr. Joy Reidenberg brave the Australian Outback to dissect a camel, the ultimate desert survivor.
