David Attenborough continues to uncover strange new worlds in the overlooked corners of the animal kingdom with LIFE IN COLD BLOOD. Like LIFE IN THE UNDERGROWTH, this documentary series uses cutting-edge filming techniques to capture Earth's lifeforms in astonishing new ways. Often thought to be primitive and unintelligent, reptiles and amphibians feature some of the most astonishing and varied behavior of all land animals. In this exploration of cold-blooded life that is anything but tepid, tortoises battle, a rare frog communicates by waving, and a cobra spits deadly venom--on Attenborough himself! Included here are all five episodes of the fascinating series: "The Cold-Blooded Truth," "Land Invaders," "Dragons of the Dry," "Sophisticated Serpents," and "Armored Giants."
