bears that live in snowy environments are white, so why are bears that live in forests brown or black?
In: Biology
There are a lot of green animals living in forests and jungles. However there are two main reasons why there are not more such animals. Firstly the most common color pigment in animals is melanin. This is a group of pigments that produce colors such as black, brown, red and yellow but no green. In fact there are very few biological substances that are green at all. So it would be a very rare mutation to cause an animal to turn green. The second reason is that the jungle floor where most animals live is very dark and brown. Most of the light is getting caught by the leaves in the canopy above and very little light actually filters down to the jungle floor. So a black or brown creature would not be out of place as it would just look like a shadow or a piece of a tree. However a green creature would often be very distinct from anything else, even the little vegetation on the jungle floor have different color and shape then what animals are able to replicate.
