In Australia, several species have become extinct in the past 25 years.This revised and updated guide provides concise accounts of all the known frogs of Australia. There are 230 species within the five native frog families: Hylidae, Limnodynastidae, Microhylidae, Myobatrachidae and Ranidae. Also included are the introduced Cane Toad and nine stowaway species that have arrived in Australia.The text for each species includes details of size, status, distribution, habitat, behavior and advertisement call.
