Several examples of vertebrate predators switching to invasive prey include the previously threatened Lake Erie water snake, Nerodia sipedon
insularum (Conant & Clay, 1937) (Squamata: Colubridae), whose preferred prey is now the exotic Eurasian round goby, Neogobius melanostomus (Pallas, 1814) (Perciformes: Gobiidae) (King et al.
