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 ...

Retinal projections in the caecilian Ichthyophis kohtaoensis (Amphibia, Gymnophiona)
Cell and Tissue Research, 1985The retinal projections of the caecilian Ichthyophis kohtaoensis were investigated by anterograde transport of HRP. The optic tract forms two bundles in the diencephalon, a narrow medial bundle in the optic tectum, and a basal optic tract consisting of few fibres.

Systematics of the caecilians (Amphibia: Gymnophiona)
1987Determining the higher level relationships of the modern amphibian order Gymnophiona (caecilians) poses a number of methodological problems. A cladistic methodology is outlined by which the phylogenetic relationships of this group can be determined objectively.

The lateral line system in larvalIchthyophis (Amphibia: Gymnophiona)
Zoomorphologie, 1979The lateral line systems of larval caecilians of the genusIchthyophis possess two types of elements, free neuromasts and ampullary organs. Free mechanoreceptive neuromasts are typical of those found in other vertebrates, and are arranged in series roughly homologous to neuromast groups in many other fishes and amphibians.

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.

The Ultrastructure of the Spermatozoon of Typhlonectes natans (Gymnophiona: Typhlonectidae)
Journal of Herpetology, 1991The spermatozoon of Typhlonectes natans consists of a long slender head approximately 18 ~im long and a distinct acrosome attached to the anterior margin of the head. A well-demarcated midpiece contains 35-40 spherical mitochondria that consist of many delicate cristae mitochondriales.

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 ...
