A fifth Northern snakehead has been caught in Virginia's Potomac River.
The illegally introduced non-native predator was caught in Pohick Bay, near Pohick Bay Regional Park and Fort Belvoir Military Installation, not far from the location at which the other four snakeheads were captured.
According to US Newswire, the fish was identified as a 36cm/14" female Channa argus.
Fisheries experts fear that the invasive species could severely damage the aquatic environment if it starts to breed by competing with native fishes for food and habitat, and, of course, eating other fishes found in the region.
