* Other mammals: While not their primary prey, they have been documented to eat small mammals like rats, mice, and even young muskrats in areas where they are abundant.
* Amphibians: Frogs, toads, and salamanders.
* Reptiles: Smaller snakes and turtles.
* Insects: Grasshoppers, crickets, and other insects.
* Crustaceans: Crayfish and crabs.
It's important to note that while they can consume mammals, they are not a significant part of their normal diet. Their primary prey source remains fish, especially smaller species like minnows, bass, and catfish.
However, their ability to eat a variety of prey makes them a very successful invasive species, as they can adapt to different environments and food sources.
