× The current book provides a synthesis of the information concern-
ing field identification of all the species and subspecies of Amphibia
and Reptilia hitherto registered in Bulgaria. It comprises 61 species
and 23 subspecies, among which 5 species (Pelophylax lessonae, P.
kurtmuelleri, Hemidactylus turcicus, Eremias arguta, Montivipera
xanthina) that have not been found yet on the territory of the
country, but which are known from sites in proximity to Bulgar-
ian frontiers. The frogs and toads are represented with 14 spe-
cies, newts and salamanders with 6 species, turtles and tortoises
with 7 species (Trachemys scripta introduced; Caretta caretta and
Chelonia mydas considered extinct), and snakes with 19 species
(Vipera aspis and V. ursinii considered extinct). The structure of
each species’ description includes the following headings: Name,
Diagnosis, General Distribution, Distribution in Bulgaria, Habitats,
and Biology. Besides in Bulgarian and Latin, all species are sup-
plemented with their English, French, German and Russian names.
All synonyms in the main herpetological literature are listed after
the currently accepted Latin name. Original keys for identification
of the families, genera and species, based entirely on morphologi-
cal characters of adult specimens, as well as on the structure of
amphibians’ eggs and larvae, are elaborated to facilitate the users.
A photo gallery, comprising original colour photos shot in nature,
and numerous line drawings of different key characters are made
for better distinction between the species. For purely conservation-
al reasons, the distribution maps not only indicate the scientifically
confirmed species distribution in the country, but also show the
areas with suitable habitats where a given species is likely to oc-
cur. The degree of suitability is indicated with a different degree
of shading: optimal (black); suboptimal (80% gray); suitable (60%
gray); less suitable (20% gray); white means unsuitable. The guide
is also introducing the readers to some general aspects of the tax-
onomy, systematics, morphology, biology and ecology of herpeto-
fauna. Special chapters are devoted to the methods of observation
and capture of amphibians and reptiles, first aid after a snake’s
bite, and the relationship between herpetofauna – humans. The
status of each species according to main biodiversity conservation
acts and conventions is given in Table 1. Being the first publication
of its kind, the book is intended for professional herpetologists,
students or nature lovers.
