The Michigan Department of Natural Resources has produced a video to help people learn the differences between a native bowfin fish and the snakehead, an invasive species that authorities are trying to keep out of the Great Lakes region.
Snakeheads are native to China but have spread in the eastern U.S. They can survive in a variety of habitats and have the ability to breathe out of water for extended periods. They have no natural predators in the U.S. and can out-compete native fish for food and space.
They haven't been found in Michigan waters. But anglers sometimes mistake them for native bowfin, otherwise known as dogfish.
The video highlights characteristics that distinguish bowfins from snakeheads.
