In the second section of this program, differences in anatomy between Wood Buffalo and Plains Bison provide viewers with an understanding of the largest land mammal of North America. The giraffe and the advantages of its long neck, tongue, and grazing habits are shown in the last section. The anatomy of the giraffe with the same number of vertebrae as humans, and the most powerful heart of any land mammal provides viewers with insights into its physiology.
