💙🦦 North American river otters are considered a keystone species, which means other species in the same habitat largely depend on the existence of river otters. 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
