Karaurus was about 20 centimetres (7.9 in) long, and very similar anatomically to modern salamanders. It probably swam through fresh water feeding on aquatic snails, worms, crustaceans and insects.[2] Karaurus is thought to form a clade with Kokartus from the Bathonian of Kyrgyzstan, together forming the Karauridae, as the sister group to crown salamanders.
