Boas can be found in nearly every habitat known to host snakes of any sort, except marine habitats. Many of the sandboas, such as the Arabian sandboa, are well adapted to live in extremely hot and dry habitats; in contrast, Eryx tataricus is found in a very cold climate in southern Mongolia. The range of the viper boa, Candoia aspera, includes New Ireland in the Bismarck Archipelago, one of the rainiest locales on Earth. The wide-ranging boa constrictor can be found in the Sono-ran Desert in northwestern Mexico, the rainforest in Brazil, and the temperate grasslands of northern Argentina.
