Supersized crabs population is on the rise. However, the increase in the number of giant crabs is a sign of the growing environmental concern.

A recent study conducted by researchers at the Aquarium Research Center of the University of North Carolina (UNC) revealed that supersized crabs are the result of higher atmospheric levels of carbon dioxide.

Researchers revealed that the greenhouse gas, pointed out as one of the factors to global warming, has made the crabs bigger, faster and stronger.

Carbon dioxide increases the acidic and carbon level of the ocean water that eventually produced the supersized crabs. In contrast to the growing crabs is the decrease the size and population of other sea creatures that include plankton, oysters and scallops.

The increase in crab size eventually led to its greater demand for food. These supersized crabs are expected to eat more of its favorite shellfish food, oyster.

Justin Baker Ries, a UNC marine geologist explained that the “Higher levels of carbon in the ocean are causing oysters to grow slower, and their predators — such as blue crabs — to grow faster.”
