Snakehead Fish are a non-native, invasive species introduced by people into the Potomac River system in 2002. They have since invaded many of the Potomac's tributaries and other streams of the Chesapeake Bay watershed. A predatory fish they feed on both large and small fish as well as dragonfly larvae, frogs, other insect larvae and even birds.

One female can produce thousands of eggs each year. In this image, you can see some eggs near the adult's mouth. These have drifted away from the main floating nest, visible in the upper right corner of this image. That yellow orange area is a nest of thousands of Snakehead eggs, which this adult is guarding.
