* Large snakes: Snakes like water moccasins and large constrictors might be able to subdue a young or weakened round-tailed muskrat.
* Alligators and crocodiles: These reptiles are opportunistic predators and could pose a threat, especially in areas where their ranges overlap.
* Large fish: Some large fish, like catfish or pike, might prey on young muskrats or those caught in vulnerable positions.
* Larger mammals: While unlikely, animals like coyotes, bobcats, and even raccoons might target muskrats if other prey is scarce.
It's important to note that predation on round-tailed muskrats is probably not a significant factor in their population dynamics. They are more often impacted by habitat loss and degradation, as well as disease and parasites.
