The spider-tailed viper is a snake with the best of both worlds: a viper’s body and a tail like a spider. Shuddering yet?
Here’s a crazy bit of evolution that I bet you didn’t expect, a snake that developed a tail to mimic its prey’s favorite meal: an insect.
Now imagine yourself a bird and you see a tasty little spider right there on the rocks. The only problem is that the spider has a viper on the other end!
Game over for the bird.
The spider-tailed viper is a native of western Iran, living among the barren rocks and trees. These snakes have the remarkable adaptation of a tail that is extremely deceptive, mimicking a spider or other native insect.
Birds of the region are adept at picking off these bugs, and promptly attack any insect that they see. Go back to the 30-second mark and get creeped out all over again by the insane way this viper can mimic a spider moving about the rocks… amazing!
