Amphibians are protected animals!
For that reason they have to be identified on the spot where they are found and without causing any damage to the animals. The present key makes this possible, even for tadpoles. The key is completed with photos and descriptions, to be sure of the identification. Using a single, easily recognizable feature can make each step through the key. Occasionally, other characteristics have to be taken into account, e.g. the initially dark temporal patches in young Green frogs or by distinction between Moor frog and Agile frog or between female Smooth newt and Palmate newt.

Although adult Amphibians live generally well hidden and shy, their larvae occur abundantly and are quite easy to catch. However, it used to be very difficult to identify the larvae, especially those from many kinds of tadpoles. Berninghausen's new and simple method now makes it possible even for the inexperienced to determine the species on the spot within minutes. Moreover this handy system is extended also to the grown up animals. This field guide containes further information on the distribution of the Central European Amphibians, mating times, calls and the appearance of the spawn. The scientific and common names of the 20 species dealt with are given in the language of ten European countries.

Explanation of symbols in this programme:
D = dorsal (back), V = ventral, underside (belly), = male, = female
Total length of larvae approximately +/- 20%.
Anura (tailless amphibians) = frogs and toads.
Caudata (tailed amphibians) = newts and salamanders.
Larvae = young stages, breathing through gills (e.g. tadpoles).
Metamorphosed animals = amphibians breathing through lungs.
