What is this?
Photographed near Turku in Southwestern Finland, at a site where only Lissotriton vulgaris is known.
T. cristatus does occur in Finland, but has only been found in the Åland islands and in the eastern parts of the country.
I. alpestris (introduced, of course) has been found in one pond, about 10 km away from this location.
The photographer identified this newt as T. cristatus, but wants confirmation. He says it was "at least 12 cm" long.
