Elephants are excellent swimmers like all other mammals. The only mammals that have to learn to swim are humans and the primates. The pachyderm’s massive body, very surprisingly, gives them enough buoyancy to float easily. They swim completely submerged, with their head above the water and their mouths below, and use all four legs to paddle. The biggest advantage that elephants have above all other mammals is their trunk. A very versatile proboscis, they use their trunk like a snorkel. This enables them to breathe normally when swimming and allows them to swim long distances.
