Calotriton

''Calotriton'', or the European brook newts, is a genus of newts native to the Pyrenees and central Catalonia (Catalan Pre-coastal Range). These amphibians were formerly placed within genus ''Euproctus'', but the genus was resurrected in 2005. Instead of ''Euproctus'', they seem more closely related to ''Triturus'', their sister taxon.
==Evolution==
''Calotriton'' and ''Triturus'' are estimated to have split approximately 8 Mya ago. This may have been associated with adaptation to fast-running, well-oxygenated mountain streams (instead of ponds in ''Triturus''), leading to some superficial similarity with ''Euproctus'' in convergent evolution: strongly depressed head and body, and reduction or even absence of lungs.〔
