According to the National Wildlife Federation, there are between three and 30 million species on the planet, although we have only identified 1.7 million of them thus far. The below photographs just scratch the surface of the diverse abundance of life on Earth, but they do so pretty magnificently.
They are all entries in this year's National Geographic Photo Contest, which is still accepting submissions until Oct. 31.
Take a look at the slideshow below for scenes from the Antarctic Peninsula to Morocco to Montana.
