This is a fully updated new edition that identifies fishes commonly seen in Australian waters. The species' entries are grouped in families in the internationally accepted scientific order. Families are arranged so that those with closely related features follow on from one another, making comparison easy. Length measurements for adults are given along with general text highlighting, diagnostic features, interesting aspects of the species and habitat. Every species account is accompanied by one or more colour photographs, nearly all of which show the fishes in their natural habitat, and a distribution map. All these features enable positive identification of over 950 species.
