Yes, otters... really not nice creatures:

From the article, about an otter attacking a seal pup:
"Finally, the sea otter positioned itself dorsal to the pup?s smaller body while grasping it by the head and holding it underwater in a position typical of mating sea otters. As the sea otter thrust his pelvis, his penis was extruded and intromission was observed. At 105 min into the encounter, the sea otter released the pup, now dead, and began grooming.
You read that correctly. After raping a baby seal to death, this psycho licked his paws, like Hannibal Lecter or something."
