Description:\nThe lizard reaches up to 15 cm (5.9 in) from the tip of the muzzle to the cloaca. The tail can be up to twice the length of the body, total length is up to 40 cm (16 in). This lizard sometimes sheds its tail (autotomy) to evade the grasp of a predator, regrowing it later.\nThe male has a larger head and a uniform green coloring punctuated with small spots that are more pronounced upon its back. The throat is bluish in the adult male and to a lesser extent in the female. The female is more slender than the male and has a more uniform coloration, often displaying between two and four light bands bordered by black spots.\nDistribution and habitat:\nThe European green lizard is native to southeastern Europe. Its range extends from southern Germany, Austria, eastern Italy, Croatia, Bosnia & Herzegovina, Serbia, Montenegro and Greece to southern Ukraine, Romania, Bulgaria and western Turkey. It is known from elevations up to 2,200 above sea level and its typical habitat is dense bushy vegetation in open woodland, hedgerows, field margins, embankments and bramble thickets. In the northern part of its range it may be found on bushy heathland and in the southern part it prefers damp locations (source Wikipedia). \n\nThis Picture is made during a Vacation in Bulgaria in May 2018.
