SD Least


Consists of 4 species:

  • Giant Snakehead (Channa micropeltes)

  • Northern Snakehead (Channa argus)

  • Bullseye Snakehead (Channa marulius)

  • Blotched Snakehead (Channa maculata)


Southeast Asia


Snakeheads have long, fully connected dorsal and anal fins. Adult snakeheads have large visible teeth on both the upper and lower jaws.


The effects of snakehead introductions are widely unknown as the species has only recently been introduced to the United States. Since they are a largely piscivorous fish, it is believed they may directly compete with native predatory fishes such as walleye and pike.

Range Expansion:

It is believed that snakeheads were introduced to lakes and rivers by aquarists and fish markets after care for the animals became difficult and/or expensive.

South Dakota Distribution:

Snakehead have not been found in South Dakota.
