Habitat
American river otters primarily inhabit freshwater rivers, lakes, streams, and wetlands across North America, from Alaska to the Gulf of Mexico. They prefer areas with abundant cover like overhanging banks or vegetation for dens, and they avoid heavily polluted or fast-flowing waters.
Diet
American river otters mainly consume fish such as trout, bass, and catfish, along with crayfish, amphibians like frogs and salamanders, and occasionally birds or small mammals. They are agile hunters that use their sensitive whiskers to detect prey in murky water, feeding primarily at dawn and dusk.
Behavior
American river otters are social animals, often living in family groups and engaging in playful activities like sliding on snow or mud banks. They are primarily crepuscular, active at dawn and dusk, and maintain territories marked by scent glands, though they can be solitary outside of breeding season. They are excellent swimmers, capable of diving up to 6 meters deep to hunt.
Conservation Status
The IUCN classifies the American river otter as Least Concern, with populations stable or increasing in many regions due to conservation efforts. Major threats include habitat destruction from urbanization and pollution of waterways.
