The orders Testudines and Rhynchocephalia had the smallest gender gap or largest percentage of female authors at 34.6% and 33.9%, respectively ( Fig. 1A ).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.
