Snakes inhabit virtually every area on Earth, with the exception of Antarctica, Iceland, Ireland, Greenland and New Zealand. Snakes vary in size and color, but most live in tropical regions and deserts and survive on land and in water.
Most snakes live in tropical areas, taking up residence in trees and on the forest floor. They also live in deciduous and coniferous forests, as well as deserts and on highlands, plateaus and prairies. Most snake species live on land, although others spend their time in freshwater and saltwater habitats. Some snakes live in dens, while others reside in trees or make homes in rocks and gardens.
