As mammals ourselves, we have always been fascinated with this most advanced class of animals, and Simon & Schuster's Guide to Mammals describes 426 species worldwide. A long and thoughtful introduction to the evolution, characteristics, and orders of mammals is followed by the entries -- all illustrated in full color -- each containing the mammal's classification, description, and habitat as well as details on behavior, feeding habits, and reproduction. The entries also feature colorful symbols to illustrate habitat, color maps to show the distribution and rarity of each species, and line drawings to indicate unusual or notable physical features.With more than 500 color photographs, Simon & Schuster's Guide to Mammals is a superb and valuable reference.
