Amphibians were the first vertebrates to live on land. From them evolved reptiles, which in turn gave rise to mammals and birds. This hall reviews the relationships, life histories, habits, behavior, and various adaptations of the coldblooded vertebrates. The display of specimens includes a group of ten-foot Komodo Dragons, the largest and most ferocious lizards in the world, brought to the Museum from a 1926 expedition to the Indonesian Island of Komodo.
