Four volume set - Entries focus on non-humans from the animal kingdom, from insects to reptiles to mammals - Early humans are addressed in an evolutionary context, and modern humans are included only for interspecies comparison or for their efforts to coexist with other species - The encyclopaedias also contain species overviews which discuss notable anatomy and physiology, habitat, behaviour and reproduction and include a sidebar listing classification, geographical location, life span, and special anatomy.
