Some species may look similar to one another but have distinctive survival strategy differences. The canyon tree frog provides an example. It lives near streams and ponds in the New Mexico mountains. It grows to be about two and a half inches in length. It is the variation in its colors that stands out. It may range from a dark grey rocky color to a woody brown color.
