Why do vipers look angry?

If you have noticed that vipers like rattlesnakes, cottonmouths, and water moccasins tend to look angry, it's mostly due to their protruding scales that gives them a furrowed brow. So it's safe to say that if you see a snake that looks mad, you should probably leave.

The saw-scaled viper (Echis carinatus) may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined. Its venom, however, is lethal in less than 10 percent of untreated victims, but the snake's aggressiveness means it bites early and often.
