Chevrotain

Source: Cracked

This picture is almost like some sort of visual illusion: Cover the lower half of the photo with your hand and it looks like a perfectly normal squirrel-size rodent, but focus on its hoofed legs instead and it's hard not to imagine it being the size of a deer.

The truth is somewhere in between: The chevrotain, or mouse deer, is the world's smallest hoofed mammal. If they wanted to recreate the plot of Bambi with these things, the hunter could save himself a few bullets by just stepping on Bambi's mom.

One might suspect that a creature that's the size of a rabbit and looks like a mashup of the two most timid animals on earth would be a pushover. Well, it just so happens that chevrotain males come equipped with, for no immediately apparent reason other than wild incongruity, a set of elongated, saber-like canine teeth. The males actually use these outsized fangs to fight with one another over territory and mouse deer ladies.
