Dr. Eric Hilton describes a preserved specimen of the invasive snakehead, Channa argus, and compares it to a Virginia native—the bowfin Amia calva. The snakehead and bowfin occupy similar niches: both have a similar build, diet, behavior, habitat, and can both survive in low-oxygen waters by gulping surface air. The snakehead is considered to be good eating and has become a popular sportfish. | Virginia Institute of Marine Science
