#GreenMammals #WhyNoGreenMammals #AnimalColors
It’s a colorful world out there when it comes to animals! 🌈 From vibrant birds to camouflaged insects, nature has blessed us with a diverse range of hues. But have you ever stopped to wonder why mammals, in particular, seem to be lacking in the color green? Let’s dive into the fascinating world of animal colors and find out why there are no green mammals.
###The Science Behind Animal Colors
Before we can understand why there are no green mammals, we need to take a closer look at how animals get their colors in the first place. Animal colors are determined by a variety of factors, including genetics, diet, and environmental factors. Here’s a quick rundown of how animals get their hues:
1. **Genetics**: Just like humans inherit traits like eye color and hair texture from their parents, animals also inherit their colors genetically. Certain genes dictate the pigments present in an animal’s fur, feathers, or scales.
2. **Diet**: Believe it or not, diet plays a significant role in determining an animal’s color. For example, flamingos get their pink hue from the carotenoid pigments found in the shrimp they eat.
3. **Environmental Factors**: Animals can also adapt their colors to blend in with their surroundings for camouflage or display dominance within their species.
###The Case of Green Animals
Now that we have a better understanding of how animals get their colors, let’s tackle the question at hand: Why are there no green mammals? While green can be found in a variety of animal species, mammals seem to be the odd ones out. Here are a few reasons why this may be the case:
1. **Evolutionary History**: Mammals are thought to have mostly descended from nocturnal, forest-dwelling ancestors. Green is not a common color in the darkness of the forest, making it less advantageous for mammals to have green fur or skin.
2. **Pigment Limitations**: Mammals produce two main types of pigments: eumelanin (black/brown) and pheomelanin (yellow/red). These pigments may not easily produce a true green color, making it difficult for mammals to exhibit this hue naturally.
3. **Camouflage Strategies**: While green may not be a common color in mammals, some species have evolved alternative ways to blend in with their surroundings. For example, the green fur of the “Green Monkey” is not actually green but appears so due to a scattering of light by the fur’s microstructure.
###Destined to Stay Greenless?
So, are mammals destined to remain greenless forever? Not necessarily! Evolution is a dynamic process, and we may see green mammals emerge in the future under the right circumstances. Scientists continue to uncover surprising adaptations and coloration strategies in the animal kingdom, so who knows what the future holds!
In conclusion, while green may not be a common color in mammals, there are numerous reasons behind this phenomenon, from evolutionary history to pigment limitations. Nature never fails to surprise us, and the absence of green mammals is just one of the many mysteries waiting to be unraveled in the colorful world of animals. 🦜🐍🐒

Pigments (chemicals with a color) are hard to make. Mammals can generally make dark brown & reddish/yellow ones, hence why you see a lot of colors based on those.
But reptiles and birds don’t have green pigmentation either! They’ve got regular old yellow like mammals, but they also have *scales* (or feathers, which are just very specialized scales) made out of thin layers of keratin. Those thin layers can produce the color blue due to thin-film interference, the same phenomenon that makes oil in a puddle or the bottom of a CD appear to have rainbow colors.
Firstly, there is a green mammal. The sloth. They are generally covered with a layer of algae that does help them blend in.
Minor trivia out of the way, the real reason is (probably because we don’t know for sure yet) that mammals are all descended from small nocturnal stem mammals in the late Cretaceous. Because they were nocturnal, vibrant colors generally weren’t useful, and so didn’t really get selected for. Dark colors however, were. As such, mammals use two types of melanin for pigmentation. Both of these are brownish, reddish colors, and comprise the vast majority of all mammal pigmentation. Using these two, you get yellows, browns, reds, and oranges, as well as black and white. You will notice every single mammal only uses these colors, or shades and tints of these colors, in their coloration. In some unique cases you do have blues, but this is not pigment but structural actually. The structure of the surface traps non blue light and lets blue light out. This is how baboons and blue eyes work. Additionally ribrant reds are from blood circulation near the surface, this is also how baboons work. You know the other half of them.
So the short answer is because we just don’t have that pigment as an option as mammals.
There are other good ways to hide in nature without being green. Whatever color you happen to be born, if it hides you well enough to survive, your offspring are going to be variations of that color.
If the animals you need to hide from aren’t very good at seeing color, then you have even more options. Tigers, for example, are almost invisible among the trees if you can’t see orange. Even coloration that breaks up your silhouette can help, because it makes you look like smaller patches of color instead of a big animal shape.
Green doesn’t come up a lot. It’s only everywhere because all plants descended from the same chloroplast and are very successful. Everything else is kinda randomly meandering through the available design space until it finds something, anything, that doesn’t get it eaten.
The only birds with green *pigment* in their feathers are turacos. Every other bird that appears green has special cells that refract light into the green and blue wavelengths.
Is there also an element of hunting carniverous animals (such as dogs) being red-green colour blind? Therefore, green wouldn’t necessarily be the best the camo against these hunters.
For clarity, I don’t know the answer. I’m just throwing this out there for inputs.
