All this combined indicates that Odobenocetops was a bottomfeeding molluscivore, detecting various bivalves or crustaceans either through, depending on the species, the use of echolocation or exceptional vision and possibly with the assistance of tactile hair. While foraging the animal would keep its head down and the tusks parallel to the sediment while the rest of the body would be held oblique due to its greater density. The tail fluke would help keep this position while also providing propulsion, whereas the forelimbs may have been used as stabilizers. Once a suitable prey item was detected, Odobenocetops could have created a powerful jet of water using its mouth (an ability also seen in belugas and orcas), excavating the target from the sediment. It would then have likely used its powerful upper lip to grasp and hold the invertebrate in place before utilizing a complex suctionfeeding mechanism created by the palate and tongue to suck out the soft parts. Once these were out, the shell could be easily discarded.
