Surprising catch.

Toby Davidson was fishing in Lake St. Clair in Michigan when he caught a fish that was unusually feisty. It was an 18-inch pacu {wiki}, a relative of the piranha.

"They told me I caught a piranha and then they said, 'Congratulations, because you will probably never catch something like this again,'" said Davison, who works for a lawn care service.
