Mudpuppies and olms

Mudpuppies and olms, which make up the Proteidae family, are descendants from creatures that lived millions of years ago. Mudpuppies (or waterdogs) are so named because of the sound they make, which many perceive to sound like a dog's bark. Olms (pictured) have adapted to live in complete darkness, and though they are blind, they have advanced hearing and smelling capabilities.
