ferret-badger
stoat | May 6, 2012 Interesting article from The Economist science section about establishing the presence of shy animals in rainforests by examining leech blood.
A highlight comes from one of my relatives:
They also found genetic material from the... small-toothed ferret-badger, which is (apparently) impossible to distinguish from the related Burmese ferret-badger without getting close enough to handle it.
