Native to China, Russia, and Korea, northern snakeheads are infiltrating the upper Potomac River and freshwater canals of southern Florida. The creatures prey on insects, crustaceans, frogs, and even birds and mammals, something made possible by the snakehead's primitive lung, a body part that allows them to live on land for 4 days! Luckily, they are delicious, meaning we can wipe out invading populations by eating them. “Snakehead fish turned out to be one of the biggest surprises among all of the invasive fish that I have eaten,” Landers says, noting that they’re starting to pop up on some restaurant menus. “These things have a taste and texture that is just about identical to swordfish.”
Supermarket Fix: If you like the taste of swordfish but aren’t ready to seek out snakehead, look for more sustainable picks like mahi mahi or mackerel.
