Elephants can swim up to six hours at a time. When you look at an elephant, the last thing you would think is that it’s particularly good at swimming, but it turns out that they’re incredibly capable! One of their greatest advantages is their trunk, which they use just like a snorkel to stay underwater for longer periods. Elephants also have great stamina, which allows them to swim for lengthy periods. When they’re tired, they can just float along thanks to their high buoyancy!
