Why do walrus spit out their food and put it back in their mouth?

Walruses often spit out their food to better position it for easier consumption. This behavior allows them to separate the edible parts from inedible ones, like shells or other debris. Additionally, it may help them savor their food, as they can taste it before fully consuming it. This feeding strategy is part of their adaptation to a diet primarily consisting of benthic invertebrates.
