ANNAPOLIS, Md. (AP) - Scientists have discovered a northern
snakehead _ a toothy invasive fish that can live out of water _
in Anne Arundel County. Biologists from the Smithsonian
Environmental Research Center were taking annual fish samples
last week when they found the 23-inch egg-bearing snakehead in
the Rhode River. The center reported the catch to the Department
of Natural Resources and U.S. Fish and Wildlife Service. The
fish, which are native to Asia, first received local attention
in 2002 when they were found in a Crofton pond. The snakehead is
a top-level predator and can crowd out native fish. It can
breathe air, survive on land and adapt and thrive in foreign
environments. Scientists are exploring whether low salinity
levels in the Chesapeake Bay allowed the snakehead to travel to
Rhode River. (Copyright 2011 The Associated Press. All rights
