Supersized crabs, caused by increasing carbon dioxide levels in the air and oceans, are gobbling up oyster beds and growing giant, lean bodies with little crab meat.
The giant crabs are coming. And they're hungry.
Researchers at the University of North Carolina's (UNC) Aquarium Research Center have found that higher atmospheric levels of carbon dioxide — a greenhouse gas that's linked to global warming — are also causing crabs to grow to bigger, faster and stronger, according to the Washington Post.
As the oceans absorb significant amounts of atmospheric carbon dioxide, the water becomes more acidic and carbon-rich, and these higher levels of carbon are giving rise to the supersized crabs.
That's bad news for oyster lovers: The shellfish are a favorite food of crabs, and big, ravenous crabs can wipe out an oyster bed in record time.
