Narrator, Allan Peck. Originally broadcast as an individual episode of the television program Nature on PBS.
Summary:
Being big can have its advantages, but it also comes with sizeable challenges. Take the world's largest lizard, the Komodo dragon, whose huge appetite means it must take on prey ten times its weight, or the tallest of them all, the giraffe, who with such a long neck must control immense blood pressure. Nature's biggest beasts must go to extraordinary lengths to thrive. For them, size does matter.
