odobenocetops

…an extinct genus of small whales that lived during the Pliocene epoch. Odobenocetops had a very flexible neck and a broad snout, like modern walruses. This suggests that it was a bottom feeder, and fed mostly on molluscs, sucking them out of their shells with a powerful tongue. Like the semi-related narwhal Odobenocetops had two large tusks (the only male specimen has one large tusk and one small tusk, it is speculated that this is true for all males but this is not confirmed) their exact function is unknown but it is thought that they might have been used as a sensory organ, like in narwhals.
