European tree frog (Hyla arborea)
The Greek lissotriton, Lissotriton graecus (Wolterstorff, 1906) is a species of newt in the Salamandridae family. It is one of the two species of lissotriton in Greece.
It is a small-sized newt, reaching 11cm in total length. Outside of the breeding season, distinguishing between males and females is difficult, as both sexes are similar in size and coloration. During the breeding season, males become darker and form a plume along the back, with black spots covering most of the body. Females also have spots, but they are mainly located on the abdominal part of the body. They lay 60-300 eggs which they wrap in leaves of aquatic plants. They mate immediately after hibernation in stagnant or slightly flowing water.
It is found in the Balkan Peninsula (Albania, North Macedonia, Bosnia-Herzegovina, Greece, Croatia and Montenegro). In Greece it is found throughout mainland Greece (except Eastern Macedonia and Thrace, where it is replaced by the eastern lissotriton), the Peloponnese and the Ionian Islands.
