I am very grateful to whatever thoughtful videographer placed this on youtube. It is footage of a beaver swimming from a viewing platform underwater at the Lincoln Park Zoo. (Apparently they can tolerate trapped beavers, just not free ones.) You see, there’s been some controversy about how beaver feet move underwater. Some artists show them moving together, like a kangaroo, instead of alternating, like we walk. See for yourself:
Case closed. Thanks “bairdfam“.
