Reptiles are already pretty weird but some lizards give the phrase "freaks of nature" a whole new meaning. They can be popular pets but lizard breeding can often lead to some less-than-desirable results. Unstable environmental factors and gene mutations can cause some of the weirdest birth defects in the entire animal kingdom. The issue is so prevalent with lizards, in particular, that photos of these reptiles are going viral.

There are a few different factors that influence these shocking lizard mutations. Obviously genetics contribute greatly to their development but environmental shifts during an egg's incubation period are much more significant than most people would imagine. Many reptile species, like geckos and alligators, have to keep their eggs at very specific temperatures. If an egg get too hot or too cold, the fetus could develop a whole host of dangerous and strange abnormalities. Changing temperatures can determine what color the lizard will be and can even affect the sex of the developing embryo.

These creepy pictures of mutated lizards are well worth a look but they may not be for the faint of heart (or stomach).
