Halisaurus is a comparatively small Mosasaur, maxing out at around 10 feet in length. It was a sleek and likely quick member of the family. Besides it's small size it it had distinctively, backward curving teeth that would likely have been used for grasping slippery prey like fish. A paper describing this species can be found below.
