<i>Psammodromus algirus</i> (IMAGE) University of Granada Caption Scientists at the University of Granada have found that the long-tailed lizard, Psammodromus algirus, is larger when living at high altitude-with a cold climate-than at a lower, and therefore warmer, altitude. In addition, lizards living at over 2,000 meters retain heat longer because they are larger.
