North American river otter analyzed. However, many other studies did not report any findings of North American beaver remains in the scat sampled. The North American river otter has few natural predators when in water. Aquatic predators include the American alligator ("Alligator mississippiensis"), American crocodile ("Crocodylus acutus"), and killer whale ("Orcinus orca"), none of which commonly coexist with the North American river otter and thus rarely pose a threat.

Terrestrial predators include the bobcat ("Lynx rufus"), mountain lion ("Felis concolor"), coyote ("Canis latrans"), domestic dog ("Canis lupus familiaris"), wolf ("Canis lupus"),
