Scientists Claim Giant Cannibal Shrimp Are Invading U.S.A.

Sightings of the massive Asian tiger shrimp, which can eat their smaller cousins, were 10 times higher in 2011 than in 2010. The giant cannibal shrimp can grow to be 12 inches long and thirst for fresh blood. They are amphibious and like to hunt out of the water at night for what they jokingly refer to as "landfood".
