Digest: Life underground and sensory adaptations in caecilians (Gymnophiona)

Evolution
Abstract 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, 2011
AbstractHigh 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, 1995
The 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, 1987
A 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.
