This month’s #SuperSnap goes to the slick pair of North American River Otters featured below from Vilas County. Otters are known to produce slide marks as they move their bodies along ice, snow, and mud on the edge of riverbanks. As the only species in the state to produce these distinct tracks, the Wisconsin DNR performs a series of aerial surveys in the winter to search for the presence of otter slide marks. This data is then incorporated into population estimates for the species.
