Zuegelepis is a species of prehistoric jawless fish from the Hendricks Formation of Michigan's Upper Peninsula. It was a thelodont which lived in the early Silurian, specifically the Aeronian stage of the Llandovery Epoch. The scales of Zuegelepis may have served in a role to defend against Parasitism, similar to the denticles of modern sharks which form large groups and cruise at slow to medium speeds.
