Long-Tailed Weasel
Seriously, a tiny weasel is the first animal on the list?!? It sure is as these creatures are the perfect blend of cuteness and darkness (if there is such a thing as a perfect blend).
While these small, slender, and fluffy animals look downright adorable they are known to be vicious killers among the small mammal world. They will gruesomely attack rodents but they make this list for their trickery.
The long-tailed weasel is known to seduce Snowshoe Hares with an elaborate dance. Sadly the hares will become mesmerized by the intoxicating dance…right before the weasels pounce on them and crush their head (I told you they had a dark side).
