Blue crabs love to eat them green crabs

Green crabs, an invasive, voracious predator of shellfish native to Eurpore and North Africa have met their mat Blue crabs have developed a taste for green crabs, keeping their population down, according to a study by scientists from the Smithsonian Environmental Research Center in Edgewater. Their results were published in the latest issue of the journal Ecology.

In one of a series of tests for the study, researchers put green and blue crabs in controlled environments with a clam that both types of crabs would normally eat.

"As soon as they came into contact, the blue crab ate the green crab, even if there was an alternate food source," said Catherine deRivera, lead researcher on the project.
