I expect to meet "Cave salamanders" Olm are noticeably more bizarre than other types of salamanders, elongated slender bodies like eels or snakes. More than a salamander, about 40 centimeters long, pale skin. No pigment, including no eyes. Because living in a cave with only darkness There was no light coming in. The small legs are short, the forefoot has 3 fingers and the hind feet 2 fingers, which reduces the shape of the organs that are not used. It has a mouth that extends long and spreads wide. Olmes can live up to 100 years and can live without eating for 10 years!!!
