In comparison to rat snake species at relatively colder regions, rat snake species at lower latitudes tend to be larger in size due to warmer climate conditions. As the global climate warms, the average body size of rat snakes at higher latitudes will become larger, which will allow the species to catch more prey and thus increase their overall ...
Ptyas mucosa, commonly known as the Oriental rat snake, [2] dhaman or Indian rat snake, [4] is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia.
