Ophiomorpha \O`phi*o*mor"pha\, n. pl. [NL. See Ophiomorphous.] (Zo["o]l.) An order of tailless amphibians having a slender, wormlike body with regular annulations, and usually with minute scales imbedded in the skin. The limbs are rudimentary or lacking. It includes the c[ae]cilians. Called also {Gymnophiona} and {Ophidobatrachia}.

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.
