Karaurus was large for a Jurassic salamander, about 20 centimetres (7.9 in) long, and very similar anatomically to modern salamanders. Karaurus is thought to have fed using suction feeding via the enlargement of the buccal cavity on small fish and invertebrates, with the well developed palatal dentition (teeth on the roof of the mouth) and marginal teeth helping to grasp prey.[2]Karaurus is thought to form a clade with Kokartus from the Middle Jurassic (Bathonian) of Kyrgyzstan, and Marmorerpeton from the Bathonian of Britain, together forming the Karauridae, which are closely related to crown salamanders.[3] Like other members of Karauridae, Karaurus is neotenic.[2]
