Blue is my favorite color. Yet, other than the obvious - the sky and the effect it has on how we see water on Earth - there is a surprising lack of blue in nature. There are very few blue plants or flowers that haven't been modified by humans, no genuinely blue mammals and no naturally blue foods (blueberries aren't actually blue in anything but name). Even blue eyes are rarer than other colors across the animal kingdom! For that reason, it's particularly special to find examples of brilliant blue on nature's great canvas. Here is a collection of some of the most beautiful...

Speaking of poisonous blue frogs, the most famous of all is the blue poison dart frog. In most cases, it is not beneficial for creatures to be blue, which probably explains why there aren't many blue animals.
