River Otter, Chincoteague National Wildlife Refuge, Virginia
The North American River Otter (Lontra canadensis) can be found throughout the United States in freshwater rivers and canals. River otters live both on the land and in the water; they can hold their breath underwater for eight minutes. River otters differ from sea otters in multiple ways, including the facts that river otters eat fish, make their dens on land, and live in freshwater rivers. River otters are less commonly seen in Chincoteague, but they inhabit the freshwater canals and can occasionally be seen swimming.
