The olm, a rare, and endangered cave-dwelling salamander, is considered one of world's largest and fiercest cave animal

Also known as 'human fish', the olm is found in the Dinaric karst caves of Slovenia, Croatia, and Italy

The olm is about a foot long and is considered one of the weirdest animals in the world

The olm is completely aquatic, and is adapted to living its whole life in the darkness of caves

It lacks any pigmentation in its skin, resulting in it being a pink or yellow-white colour

Olms are completely blind and navigate the darkness using their vibration-sensitive auditory system

The olm is an ambush predator, lurking silently and completely still, waiting for its prey

Research has shown that, in extreme cases, olms can survive for a decade without feeding
