The Florida Keys National Marine Sanctuary is home to the worlds third largest coral barrier reef, and is home to all kinds of diverse species of flora and fauna. To take pressure off the reef and allow for regeneration, the retired Military ship Vandenberg was deliberately sunk in 2009 which has since given divers and marine life a new space to inhabit. However, one of its new inhabitants is the invasive worm snail, the Vandy. Could this non-native species spread past the ship and to other coral reefs?#RealWild #Documentary
