The Assassin Bug

Like a real-life version of the Predator—that's barely a half-inch in size—the aptly named assassin bug wears the bodies of its victims like trophy armor after liquefying and consuming their innards. Disgusting.

After it's made a kill, the assassin bug—which calls Malaysia home—injects its victim with a special enzyme that dissolves and softens its guts so they can be easily sucked out. And once all that's left is the insect's empty shell, the assassin bug attaches those exoskeletons to its back using a sticky secretion, piling them high to create a thick layer of protective armor that also serves to confuse its enemies.

This amazing insect (Acanthaspis petax) belongs to the Reduviidae – which consists of about 7000 species, making it almost the largest family in the true bugs (or hemiptera) order. Although fascinating it is perhaps a relief to learn that just a few species make a habit of lugging the emptied out carcasses of their victims around with them!
