💡 Trivia Boars wash their food

[Beatriz9]

If you thought boars weren’t one of the smartest animals, think again. At the Basel Zoo in Switzerland, zookeepers watched wild boars pick up sandy fruit, carry them to water in their enclosure and wash them before eating. The zookeepers aren’t quite sure why wild boars clean their food, but they think chewing on sand or gravel isn’t comfortable, especially when it comes to their teeth. Experiments also showed that the boars could distinguish between clean and sandy apples—they only washed the sandy ones. According to the Basel Zoo’s website, “washing dirty food is behavior which makes sense from an evolutionary perspective.”
