FPL | Asian Swamp Eel

Asian Swamp Eel

Origin: Eastern and southern Asia

Impacts: Asian swamp eels were first introduced to the US in Hawaii in the early 1900s. This species adapts quickly to new environments. It has the potential to become widespread in the U.S. and impact a variety of native aquatic and wetland species, and eventually entire ecosystems.

The Asian swamp eel preys on a variety of animals, including crayfish, shrimp, worms, frogs, tadpoles, and other fishes.

Asian swamp eels can survive both in hot and cold climates, have no known predators in the U.S., can breathe air, and can easily move across land.

Swamp eels increase their population without detection because they are active primarily at night.

Asian swamp eels have not yet been found in Everglades National Park, but they have been found within less than 0.5 mile from the eastern border of the park.
