North American otters are relatively high on the food chain but do have predators:
* Large mammals: Wolves, black bears, and grizzly bears, especially targeting cubs or sick or injured individuals.
* Other predators: Bobcats, coyotes, and in the southern U.S., alligators and crocodiles.
* Birds of prey: Golden eagles and occasionally bald eagles may prey on smaller or juvenile otters.
These interactions are not always common because otters are quick, agile, and use dense vegetation and waterways for cover and escape.
