Cold-blooded but rarely clammy, reptiles are represented by such models as turtles, snakes, crocodilians, and lizards.  When watching a large iguana basking on a rock, it’s easy to see the dinosaur ancestry (despite the types of changes that result from millions of years of evolution).  Alligators and crocodiles, on the other hand, are nearly pristine replicas of their pre-historic lineage.  Although much more commonly encountered in the tropics and deserts, some extremely well-adjusted reptile species can be found well into the arctic circle.  This album primarily features turtles, tortoises, and snakes from the a variety of different habitats.
