There is sexual dimorphism in the wolverine, with a typical adult female weighing 8-10 kg (17.6-22 lbs.) and adult male 12-14 kg (26.4-30.8 lbs.). We are not aware of a documented weight of a wild adult in excess of 20.5 kg (45 lbs.). The largest individual (male) that we are aware of weighed 25 kg (55 lbs.) and was born and raised in captivity.
