External Morphological Features of the Gills of Ichthyophis bannanicus Embryo (Amphibia, Gymnophiona)
The gills of Ichthyophis bannanicus have yet to be investigated. This paper describes the external morphological features of the gills of mature I. bannanicus embryos exhibiting three pairs of gills on their neck region. Each gill is composed of an axis and filaments. In newly released embryos, the...
