They are a top predator and their presence also reflects the health of the ecosystem around them. Find river otters, and you will find healthy streams and rivers.  See them at American Trail! | Smithsonian’s National Zoo and Conservation Biology Institute | Facebook

North American river otters have a third eyelid, or nictitating membrane, that protects the eye and allows the otter to see when swimming underwater. The otter's ears and nostrils close underwater.
