Around 7:20, they said that the wolverine is the largest and deadliest Mustelidae member. Uh, a partially-incorrect line here and here's why: a. In terms of deadliest, it is a toss-up between the wolverine and honey badger. b. Wolverines are the largest land-dwellers of that family. However, the overall heaviest is the sea otter. The longest is the giant river otter. Then again, the giant river otter being amphibious does technically include being a land-dweller at times. Thus, the wolverine is the largest mainly-found-on-land Mustelidae member. Now, I understand maintaining that line in the eventual DVD/B-D releases (Funi and native Japanese versions). However, it is technically incorrect the wolverine is the largest Mustelidae member.
No argument there. The honey badger is smaller than the wolverine but rivals or exceeds the wolverine in terms of being a bad-ass.
