Vipers

There are as many vipers hiding in the grass as there is evil lying beneath a beautiful countenance.

The Ogress knew the voice of the Queen and her children at once, and being furious at having been thus deceived, she gave orders (in a most horrible voice which made everybody tremble) that, next morning by break of day, they should bring into the middle of the great court a large tub filled with toads, vipers, snakes, and all sorts of serpents, in order to have the Queen and her children, the chief cook, his wife and maid, thrown into it, all of whom were to be brought thither with their hands tied behind them.

Vipers everywhere!

The most "bloodthirsty predator" is thought to be the automobile, exceeding by the number of its human victims all tigers, sharks, and vipers taken together.

Gaboon vipers have unique horns on the tip of their noses.
