Abstract

Mangione, S., Garcia, G. and Cardozo, O.M. 2011. The Eberth–Katschenko layer in three species of ceratophryines anurans (Anura: Ceratophrydae). —Acta Zoologica (Stockholm) 92: 21–26.

In this study, we made a morphological analysis by optic microscopy of the dorsal and ventral skin of the body of Ceratophrys cranwellii, Lepidobatrachus llanensis and Chacophrys pierotti to verify if there exist shared integumental characters in relation to the Eberth–Katschenko layer (E–K layer). The presence of cells associated with this layer, historically considered acellular, is one of the leading characters. This study contributes to support that the E–K layer would be the remnant of an ancestral dermal skeleton and not a physiologically significant formation. Hence, the presence of cells associated with the E–K layer would represent a synapomorphy for Ceratophrydae.
