Where did they come from?

Where can they be found in South Dakota?
- No species of snakehead is currently in South Dakota.
What do they look like?
Snakeheads have long, fully connected dorsal and anal fins.
Adult snakeheads have large visible teeth on both the upper and lower jaws.
Why are they a problem?
- 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.
How are they spread?
- 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.
