Madagascar is home to an extraordinary number of frog species, with nearly all native species endemic to the island and many not yet described by science While a considerable percentage of these species occur in the eastern humid forests of the island, many are found in the poorly documented dry forests of west and south Madagascar As a result of various human pressures, these animals are among the most threatened vertebrates on the island In this highly illustrated French language guide, the authors provide both a detailed introduction to the amphibians of Madagascar as well as the most comprehensive information ever assembled on the forty five species of frogs known from the dry western areas, with details on identification, calls, tadpoles, distribution, habitat, and conservation status
