Mammals Encyclopedia & Field Guide

Mammals are an exceptionally diverse class of endothermic (warm-blooded) vertebrates characterized by the presence of mammary glands, specialized hair or fur, neocortex brain structures, and three middle ear ossicles. Ranging from the 2-gram bumblebee bat to the 150-tonne blue whale, mammals dominate terrestrial and marine apex niches across all seven continents.
