I made the stereotypical shape of the gecko and then used my imagination on the color. This may or may not be an exact representation of a real gecko. One thing we can be sure of is that God loves variety. So if this is not a presently existing gecko species, who is to say that it never existed, or that it will not exist in the future?
Here is a bunch of pictures of geckos. See if you can match up my version to an actual gecko!
