epa11422261 Otter Tom hunts for fish at Zurich Zoo, Zurich, Switzerland, 19 June 2024. Once widespread, the endangered species of European otter is only slowly returning to Central Europe. To ensure that reintroductions are possible if necessary, the otters are one of the few species at the zoo to receive live food. This allows future offspring to learn how to hunt and would prepare them for reintroduction into the wild. EPA/MICHAEL BUHOLZER
