Gymnophiona Family Caeciliidae
2012This chapter presents short descriptions, data on the distribution, reproduction and natural history of the species of family Caeciliidae now known for the country. It discusses 5 species such as Caecilia gracilis, Caecilia tentaculata, Microcaecilia rabei, Microcaecilia taylori, and Microcaecilia unicolor under this family.Keywords:Caecilia gracilis ...

An appreciation of the physiology and morphology of the Caecilians (Amphibia: Gymnophiona)
Comparative Biochemistry and Physiology Part A, Molecular & Integrative Physiology, 1999The Gymnophiona are the least well known amphibian order, an unfortunate situation because these animals can clarify many aspects of amphibian natural history, vertebrate evolution, and the physiology of viviparity and fossorial life. Our aims are to assemble a number of topics about the current knowledge of Caecilian physiology and morphology, and to ...

Visual projections in larval Ichthyophis kohtaoensis (Amphibia: gymnophiona)
Developmental Brain Research, 1985The visual projection patterns of retinal efferents were studied in larval Ichthyophis kohtaoensis by means of anterogradely transported HRP. Our results show in all larvae a projection contralateral to a thalamic terminal field, a pretectal terminal field, and a basal optic neuropil, but only a sparse innervation of the contralateral tectum.

Electrophoretic patterns of certain proteins in caecilians (amphibia: gymnophiona)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. A maximum of 15 loci from five genera of caecilians (Amphibia: Gymnophiona or Apoda) were examined. Species include Ichthyophis glutinosus, Geotrypetes seraphini, Caecilia occidentalis, Gymnopis multiplicata , and Dermophis mexicanus . 2. 2.

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.

Comparative morphology of caecilian sperm (Amphibia: Gymnophiona)
Journal of Morphology, 1994AbstractThe morphology of mature sperm from the testes of 22 genera and 29 species representing all five families of caecilians (Amphibia: Gymnophiona) was examined at the light microscope level in order to: (1) determine the effectiveness of silver‐staining techniques on long‐preserved, rare material, (2) assess the comparative morphology of sperm ...

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.

Cartilage in the cloaca: Phallodeal spicules in Caecilians (Amphibia: Gymnophiona)
Journal of Morphology, 1998The presence of spicules (also termed spines, teeth, or denticles) on the intromittent organ, a character unique to male members of some species in the African caecilian family Scolecomorphidae, has long been known (Noble, '31; Taylor, '68; Wake,'72; Nussbaum,'85). However, their organization and structure has not been examined.

Evolution of Cranial Shape in Caecilians (Amphibia: Gymnophiona)
Evolutionary Biology, 2014Insights into morphological diversification can be obtained from the ways the species of a clade occupy morphospace. Projecting a phylogeny into morphospace provides estimates of evolutionary trajectories as lineages diversified information that can be used to infer the dynamics of evolutionary processes that produced patterns of morphospace occupation.
