North American River Otter
One thing that we see on the river every now and then is the North American River Otter (Lontra Canadensis). This mammal, which belongs to the weasel family, can go by many names depending on the region in which it is found. Some of the most common names are Northern River Otter or the Common Otter. This otter is a semi-aquatic mammal that is endemic, or native to, North America. The Otter feeds primarily on fish but is also known to prey upon small mammals. A full grown adult Otter can weigh between 11 and 30 pounds. This particular mammal is greatly affected by environmental pollution and because of so much recent development in the United States their habitat has been greatly reduced.
These little guys are greatly adapted to the aquatic life. They have developed a thick oily fur to keep them warm and dry in the water. They also remain active all year round. And tend to be more nocturnal during the spring, summer, and fall seasons but due to a shortage in food will be seen moving around more during the daytime. They can hold their breath for up to 4 minutes, and typically, will form their dens in the banks along the sides of the rivers. Each den will normally have several tunnels leading to it to allow for escape access. Keep your eyes open for these friendly fellas while we’re on the river, and you just may be lucky enough to see one in it’s natural habitat. AWESOME!
