Range of Enhydrocyon fossil evidence

Enhydrocyon's dentition suggests this animal was a hypercarnivore or mesocarnivore.[2] Species of Enhydrocyon were relatively large, powerfully built carnivores with a short snout and deep jaws reminiscent of a jaguar.[3] These features give the skull a shape resembling that of the extant sea otter (Enhydra), prompting the scientific name.[4] With an estimated weight of about 10 kilograms (22 lb), this was the earliest genus of canid adapted to be specialized predators.[4]
