Invasive Species

The past year was loaded with turmoil for the Great Lakes. A new president tried to cut $300 million in  restoration projects. Homes were flooded along Lake Ontario. And one of the scariest invasive species -- the Asian carp -- was found less than 10 miles from Lake Michigan.

The Great Lakes offer lots of spookiness -- from century-old shipwrecks to blood-sucking animals. For Halloween, we pulled together some of the creepiest photos. Take a look -- if you dare.

Researchers recently announced the discovery of over 7,000 grass carp eggs in a Lake Erie tributary.  The good news? This isn’t the Asian carp species we’re trying to prevent from entering the Great Lakes.  The bad news? Grass carp pose a different threat. 

Asian carp is a catch-all term for four different species of invasive carp: black, grass, silver, and bighead.
