“They can have millions of young,” explained the Smithsonian Environmental Research Center‘s Darrick Sparks. “If they’re old enough, they will start to have little tufts on their claws, that’s how they got their name the ‘mitten crab.'”

And Sparks says the crabs very aggressive. “They can get into intakes, there are so many of them they can clog them,” he said.

He says if you see one, call environmental officials so researchers can gather information about where these crabs have been found.
