DUBUQUE, Iowa —

Friends fishing for walleye in northeast Iowa stumbled upon an epic lunch battle between two snakes this month.

Adam Maas and Chris Valentine were at the Massey Marina in Dubuque County when they saw the snakes snacking on the same frog. Valentine snapped a couple of photos (see them below) and Maas posted them Monday in the Iowa Critters Facebook group .

Maas said they're not sure which snake won the game of heads or tails.

"The snakes (wrestled) each other into the Mississippi River and drifted downstream, rolling and fighting as they disappeared out of sight," he said.
