how are reptiles distributed zoogeographically?

Question

I would like to know how reptiles are distributed zoogeographically

Answer 1

At one time reptiles could be found in the land, air, and sea (fresh and marine) everywhere on Earth. They have over the past 165 million years become primarily land animals. There are still many freshwater species and a handful of marine but none in the air anymore. Most live on land but many still live near water and are very good swimmers, like snakes and alligators, for example.

Answer 2

Being poikilothermic, they prefer warmer regions; if you estimate that their diversity is greatest in the tropics and decreases as you go polarward you're going to be fine. There are not many places that you won't find reptiles, either. I don't know of any modern reptiles in Greenland or Antarctica, but other than that, I believe they can be found on every significant land mass on Earth.
