An invasive fish named the Northern snakehead has been found for the first time in a pond in Gwinnett County, Georgia. The Northern snakehead (pictured) is native to the Yangtze River basin in China, but has been found in 14 U.S. states. The fish species can grow 3-feet long and survive for up to four days out of water. Officials are concerned the predatory species will overtake native aquatic wildlife species, since it is known to eat other fish, frogs, small reptiles, crustaceans, birds and some mammals. The Georgia Department of Natural Resources is telling people who encounter the fish to 'kill it immediately'.
