Nature is one powerfully weird force. This fact can be readily exemplified by observing genetic mutations. While color mutations such as albinism are a far more mild sampling of this realm, sometimes nature can produce some truly bizarre genetic mutations. These mutations often make for crazy scary animals - and if not completely scary, they're at least astonishing.

Some See-Through Frogs
If a three-headed frog isn't solid enough proof of the effects of environmental pollution, maybe these transparent frogs are. Russian scientists blame environmental pollution for the mutant transparency of several frogs captured in central Russia. Their organs, skeletons, and even their beating hearts are blatantly visible through their skin. Some of them even have extra growths or limbs.
Vladimir Vershinin, head of zoology at the Ural Federal District University's Institute of Natural Sciences, added about the situation: "Frog eggs do not have their own membrane to protect them from a polluted environment."
A Two-Faced Cat
Meet Frank and Louie, the longest living Janus cat on record. "Janus" refers to the Roman God depicted with two faces, and the condition contributed to the formation of two faces is known as diprosopia. This condition caused Frank and Louie to have three eyes, two noses, two mouths, and one brain.
Typically, Janus cats die shortly after birth. However, Frank and Louie lived to be 15 years old and even procured their own Guinness World Record in 2006.
A Duck Born With Four Legs
Stumpy was born at the Warrawee Duck Farm in the United Kingdom. He seemed to absolutely "stump" his owner Nicky Janaway, so much so after his birth she had to keep recounting his four legs. Initially, Stumpy ran around on two of his legs while the extra ones dangled behind. Over time, one of Stumpy's legs got stuck in a fence and had to be removed. His last extra leg eventually turned black and fell off - leaving him with tiny stumps behind his two functioning, normal legs.
A One-Footed Snake
This one-footed snake was found scaling the wall of a woman's bedroom in Southwest China. Dean Qiongxiu, 66, claims the reptile was "working its way along the wall using his claw." She then beat the snake to death with a shoe before putting the body in a bottle of alcohol to preserve it. The 16-inch long snake was studied at China's West Normal University.
The most common snake mutation is the growth of a second head, but they tend to have little change of surviving in the wild, since the heads usually attack each other.
