An incident of wolf, Canis lupus, predation on a river otter, Lutra canadensis, in Minnesota

Abstract

Evidence was found of Gray Wolves (Canis lupus) killing and partially, consuming a radio-marked River Otter (Lutra canadensis) in Voyageurs National Park, Minnesota. There is little evidence in the literature to suggest that Otters are a regular source of prey for Wolves, however, wolves may incidentally kill River Otter.
