This four poster set provides a comprehensive overview of the living vertebrates. Animal life is now undergoing the transition from the Linnaeus classification system to the new cladistic classification system. Birds have been reclassified under the new system. There have been many systems proposed for the other animals, but none has been widely accepted. This required that the posters present the animals in the context of their existing orders. Each of these posters presents all of the orders within the group. Marsupials and cartilaginous fish contain so many orders that they are presented as super orders.
   Each order is introduced by the common name or names (such as Whales, Dolphins and Porpoises), followed by the biological name (Cetacea), the number of species and a brief description. A great many representational species are beautifully shown, all identified by both common and biological name.
   This is the first time that a comprehensive overview of this enormous and complex subject has ever been presented on posters. This set is invaluable for life science classes and anywhere else that the study of animals takes place.
