Albanian water frog
The Albanian water frog (''Pelophylax shqipericus'') is a species of true frog (family Ranidae) and is native to Albania and Montenegro. As its common name suggests, it prefers aquatic environments. The Albanian water frog is an endangered species and known populations are currently in decline. Significant threats to its habitat are presented by pollution and by drainage of wetlands, and a more direct threat is the aggressive collection of the species for commercial purposes.
The frogs are medium-sized and males sometimes bear a distinctive bright green stripe down the length of the backbone. Otherwise males are green to light brown in overall colouring with large black or dark brown spots. Females are olive green or light brown in colour and also bear brown or black large spots. As befits a species that prefers wetland habitats, the webbing on the feet extends to the tips of the toes.
==Taxonomy==
''Pelophylax shqipericus'' was first described in 1987 under the name ''Rana shqiperica'' in the ''Proceedings of the Academy of Natural Sciences of Philadelphia''. The specific epithet ''shqipericus'' comes from Shqipëria, the Albanian word for Albania. Many species that were once included in the genus ''Rana'' were moved to separate genera at the beginning of the 21st century, when detailed molecular phylogenetic data made a distinction among the species more clear. ''P. shqipericus'' is one such species transferred from ''Rana'' to ''Pelophylax'' on the strength of the new DNA sequencing data.〔
