Gymnophiona is the group of amphibians that includes the legless caecilians and all amphibians more closely related to them than to frogs or salamanders (the "stem-caecilians"). The name derives from the Greek words γυμνος ("gymnos", naked) and οφις ("ophis", snake), as the caecilians were originally thought to be related to snakes.
Question: Caecilians were originally snakes. True, False, or Neither?
