Gallery | Ancient Leviathan | Olm | olm_head_gills

The olm is almost entirely blind. It has no need for eyes in the darkness of its caves and as it grows up, they stop developing and are eventually covered by layers of skin. Nonetheless, the hidden eyes and even parts of its skin can still detect the presence of light. The olm also has an array of supersenses, including heightened smell and hearing and possibly even the ability to sense electric and magnetic fields. Photo by Arne Hodalič
