Snakehead fish live in a wide variety of habitats. This fish species has the ability to breathe out of water anywhere from 3 to 7 days. This allows for the potential ability to move from one body of water to another using its pectoral fins, but the process is slow and usually unsuccessful.
These fish are voracious carnivores.
Northern snakehead fish have been reported in a handful of states on the east coast and in California. The only established population appears to be in Arkansas.
As with many non-native and invasive species, snakehead fish have no natural predators in the United States. This allows for competition and consumption of native fish species. Additionally, Northern snakehead fish can survive in waters with low oxygen levels, giving them a competitive advantage over native species.
Means of Introduction:
Release from fish markets.
Native look-alikes and how you can tell them apart from a Northern snakehead:
- Burbot: A split dorsal fin and barbels on the lower jaw are features that separate this species from snakehead.
- Bowfin: Much shorter anal fin than snakehead fish, males and juveniles will have a characteristic black spot at the base of the tail.
- Mudpuppy: Aquatic salamander with 4 legs, a flattened tail, and reddish gills behind the head.
