In the Western Hemisphere, caecilians live in an area that extends from central Mexico through Peru, Bolivia, Paraguay, and northern Argentina. The water-dwelling or partially water-dwelling species live mainly in the regions of the Orinoco and Amazon rivers, but some live in an area that extends from Colombia to northern Argentina and Uruguay. In the Eastern Hemisphere caecilians live in eastern and western Africa except the Sahara, in the Seychelles, India, Sri Lanka, Southern China, Cambodia, Laos, Vietnam, and much of Malaysia to the southern Philippines. Caecilians do not live in Madagascar, much of central Africa, or Australia.
