It got that nickname because it can walk on dry ground.
Caleb Newton caught the 17-pound, 6 oz. fish in the Potomac River Saturday.
He says he could barely fit it in his cooler.
If it stands, the catch is 2 oz. more than the current world record.
But this record isn't really good news. Snakehead fish are not native to Virginia or even America.
They have no natural predators except for themselves.
Snakehead fish eat everything including each other.
When they run out of food, a snakehead can just walk to another nearby waterway.
And the fact that they are getting bigger, just means those appetites are also growing.
