Book excerpt: This useful guide provides a comprehensive overview of the wide variety of snakes, lizards, crocodiles, turtles and tortoises to be found in Borneo. Over 130 species, primarily native but with the odd exotic, are included. Each description is supported by a clear colour photograph taken where possible in the snake's natural habitat. The guide looks at the more common species as well as focusing on some of the rarer, and in some cases highly endangered, species.
