''Askeptosaurus'' is an extinct genus of aquatic reptile related to the thalattosaurian group. Their remains have been found in Italy and Switzerland. ''Askeptosaurus'' was a very thin, elongated creature, that probably swam like an eel. Its tail was very long, accounting for around half of the animal's total length of , and its webbed feet would have been well suited for steering itself through the water. Judging from its long jaws, it primarily ate fish. ''Askeptosaurus'' probably hunted in deep waters, because it had large eyes suited to conditions of low light. Like ichthyosaurs, it also had a protective bony ring around the eyes, which would have prevented them from collapsing under the immense water pressure of great depths.〔 ==References==
