@Frank Apisa,
I also saw those documentary specials on wolverines a few times. It gets me thinking of the song 'Bad, Bad, Leroy Brown'. Pound-for-pound they're the lean-mean-fighting-machine...fiercest animal in the woods. Their Latin name translates to glutton.
It can reduce a large animal ...let's say a moose, down to bones in a short period of time. These critters live up above the tree-line and gallop for a long time in hip-deep snow..and can eat or reduce carcasses down to just hooves and hip-bones. They'll sniff out a carcass or bones beneath the snow when other critters gave up on them days or weeks prior.
Oh, and if the carcass is frozen solid, they can still eat as they have a molar turned 90 deg on the roof of their moth that allows them to shred away.
The sad part, from what is known, their numbers have dwindled and habitat has been moving further northward where they're rarely seen in Michigan anymore..and mostly found up in northern Canada and Siberia..far removed from civilization.
