Extreme variation in the atrial septation of caecilians (Amphibia: Gymnophiona) [PDF]

open access: yesJournal of Anatomy, 2014
AbstractCaecilians (order Gymnophiona) are elongate, limbless, snake‐like amphibians that are the sister‐group (closest relatives) of all other recent amphibians (frogs and salamanders). Little is known of their cardiovascular anatomy and physiology, but one nearly century old study suggests that Hypogeophis (family Indotyphlidae), commonly relied upon

Morphological Evidence for an Oral Venom System in Caecilian Amphibians

open access: yesiScience, 2020
Summary: Amphibians are known for their skin rich in glands containing toxins employed in passive chemical defense against predators, different from, for example, snakes that have active chemical defense, injecting their venom into the prey.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

A new lungless caecilian (Amphibia: Gymnophiona) from Guyana [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2009
We report the discovery of a single specimen of a small, terrestrial, lungless caecilian, the second known taxon of lungless caecilians. It differs from all other caecilians in lacking open external nares, and from the large aquatic lungless species described by Nussbaum & Wilkinson (Nussbaum, R. A. & Wilkinson, M. 1995

Anatomy of the female reproductive system and sperm storage of the viviparous caecilian Typhlonectes natans (Gymnophiona: Typhlonectidae)

open access: yesActa Biologica, 2018
Here, we describe the anatomy of the female reproductive system of the aquatic, viviparous caecilian Typhlonectes natans. We conducted our research on two adult females using light microscopy and reflected our results with the available literature data ...

Histology of the trachea and lung of Siphonops annulatus (Amphibia, Gymnophiona) [PDF]

open access: yesRevista Brasileira de Biologia, 2000
The structure of the trachea and lung of Siphonops annulatus was studied in ten specimens of routinely fed animals. The trachea is constituted mainly by incomplete cartilage rings lined by a respiratory epithelium (ciliated and mucous cells) with variable morphology according to the region observed.
