The structural organization of the kidney ofTyphlonectes compressicaudus (Amphibia, Gymnophiona)
Anatomy and Embryology, 1986The structural organization of the kidney of Typhlonectes compressicaudus (Amphibia, Gymnophiona) was studied by light microscopic (LM) examination of serial paraffin and semithin Epon sections. The kidney is slender and quite long and has a mesonephric segmental construction; the excretory duct (Wolffian duct), running along the lateral side of the ...

A nine-family classification of caecilians (Amphibia: Gymnophiona)
Zootaxa, 2011We propose a new family-level classification of caecilians that is based on current understanding of phylogenetic relationships and diversity. The 34 currently recognised genera of caecilians are diagnosed and partitioned into nine family-level taxa.

Digest: Life underground and sensory adaptations in caecilians (Gymnophiona)
EvolutionAbstract Do caecilians retain some degree of vision? Navarrete Méndez et al. (2025) used an integrative approach to show that the long-wavelength-sensitive (LWS) opsin gene is present and that retinal morphology remains intact across all eight caecilian families investigated.

Deciphering morphological variation in the braincase of caecilian amphibians (gymnophiona)
Journal of Morphology, 2011AbstractHigh levels of morphological homoplasy have hindered progress in understanding morphological evolution within gymnophione lissamphibians. Stemming from the hypothesis that the braincase has the potential to yield phylogenetic information, the braincases of 27 species (23 genera) of gymnophione amphibians were examined using high‐resolution ...

The Spermatogenic Cycle of Dermophis mexicanus (Amphibia: Gymnophiona)
Journal of Herpetology, 1995The general notion that amphibian reproduction in the tropics is non-cyclic and aseasonal (cf. Duellman and Trueb, 1986) is countered by the spermatogenic cycles of caecilians. In fact, for virtually all caecilians investigated, spermatogenic cycles (and particularly sperm release, fertilization, and hatching or birth) are synchronous and seasonal ...

A New Genus of African Caecilian (Amphibia: Gymnophiona)
Journal of Herpetology, 1987A new genus, Sylvacaecilia, is proposed for the species Geotrypetes grandisonae. The species is distinctly different in a number of features of osteology, soft tissue morphology, and life history, thus warranting generic status.
