National Geographic reported that at Basel Zoo in Switzerland, zookeepers watched adult and juvenile wild boars pick up sandy apples and bring them to a nearby creek in their environment to wash before eating. Though some items like sugar beets were eaten without the human-like behavior, the boars brought a whole dead chicken to the creek to wash before chowing down. One ecologist called this a “luxury behavior.” You’d never believe the 12 animals that are probably smarter than you.
