North American River Otter

Behavior and Communication North American River Otters communicate and behave in their own unique way. River Otters live in a fresh water source. Rivers and lakes are two examples of where they live. They will travel in groups as large as 20 otters. That makes sense because they are always together. The otters often sleep holding hands. They do that so they don’t drift down the stream. They produce sounds like screams, chuckles, squeals, etc. They also communicate to each other vocally. That is how North American River Otters behave and communicate.

Their bodies are like this so they can glide through the water easily. All four feet are webbed. Their feet are webbed so they can swim faster. These river otters have a long tail for balance. River otters have short but powerful legs. They need powerful legs to swim faster, run faster on land, to run away from predators, and to catch prey. The North American River Otters need all of these things to survive.
