Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself sounds alarming, most mutations are harmless and invisible.
The more noticeable ones, however, can produce features that are quite rare for the species.
To give you a sense of how these fascinating genetic quirks show up in nature, we’ve put together a gallery of animals — from cats and mice to crabs, penguins, and beyond — each displaying traits that make them stand out from their peers.

#8 My Parents Got A Maine Coon Kitten With A Million Toes! His Name Is Chino
I don’t even know how to describe it, his front paws have almost another paw on it, like where a human would have a thumb he has this 3 toed paw. His feet are little paddles with 8-9 toe beans. I’ve never seen a cat with so many fingers. My boyfriend and I have a poly cat with one extra little thumb on his front paws but Chino is the most toed cat I’ve ever met!

#32 I Was Very Fortunate To Spot This White Eastern Gray Squirrel In Highlands North Carolina
The white squirrel is actually a genetic anomaly due to a mutated gene from the common Eastern gray squirrel. It is called leucism, which is a condition characterized by reduced pigmentation in animals caused by a recessive allele. Unlike albinism, it is a reduction of all types of skin pigment, not just melanin.
