The complete mitochondrial genome of the giant electric ray, Narcine entemedor (Elasmobranchii: Torpediniformes)

Mitochondrial DNA Part A, 2014
The complete mitochondrial genome of the giant electric ray is 17,081 bp long (GenBank accession KM386678) and includes 2 ribosomal RNA, 22 transfer RNA, 13 protein-coding genes, an origin of replication, 2 non-coding regions. The mitochondrial gene arrangement is similar to that found in other batoids.

Molecular characterization and chromosomal localization of spermatogenesis related sequences in Torpedo torpedo (Chondrichthyes, Torpediniformes)

Marine Genomics, 2009
Cytogenetic data in cartilaginous fishes are currently very inconsistent, considering that the karyotype morphology of only about seventy living species is actually known. Only in the last few years different molecular approaches, first of all physical mapping on metaphase chromosomes, have been used to investigate the cytotaxonomic relationship ...

Narcine baliensis, a new species of electric ray from southeast Asia (Chondrichthyes: Torpediniformes)

Zootaxa, 2016
A new species of numbfish, Narcine baliensis, sp. nov., is described from the tropical eastern Indian Ocean from Indonesia. It is superficially similar to N. brevilabiata and N. atzi in aspects of its color pattern, but is distinguished from both congeners in details of its color pattern, in tooth band morphology, and in proportions of its dorsal fins,

Organization of the vitelline envelope in ovarian follicles of Torpedo marmorata Risso, 1810 (Elasmobranchii: Torpediniformes)

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2009
AbstractIn Torpedo marmorata, the vitelline envelope (VE), an extracellular envelope surrounding the growing oocyte, consists of fibrils and amorphous materials that are deposited in the perivitelline space starting from the initial steps of oocyte growth.

Tetronarce cowleyi, sp. nov., a new species of electric ray from southern Africa (Chondrichthyes: Torpediniformes: Torpedinidae)

Zootaxa, 2015
A new species of torpedo ray, Tetronarce cowleyi, sp. nov., is described from specimens collected from the southeastern Atlantic Ocean. The new species is placed in the genus Tetronarce based on a uniform dorsal coloration and absence of papillae around the spiracles.

The first fossil record of the genus Benthobatis (Torpediniformes, Narcinidae) from the Miocene Yatsuo Group of Japan

Palaeoworld, 2017
Abstract Benthobatis sp., a deep-sea electric ray of Narcinidae (Torpediniformes), is described from the Middle Miocene Yatsuo Group in Central Honshu, Japan. This is the first fossil record of the genus Benthobatis in the world. The occurrence of Benthobatis demonstrates subtropical paleoenvironments in Central Honshu during the early middle ...

The impacts of comparative anatomy of electric rays (Batoidea: Torpediniformes) on their systematic hypotheses

Journal of Morphology, 2013
ABSTRACTThe Comparative anatomy of the 11 recognized genera within Torpediniformes is described, systematically categorized, and illustrated in a comprehensive photo‐atlas. Data are compiled into a character matrix and cladistically analyzed using parsimony to test hypotheses about the previously recognized subfamilies, while reconstructing the ...

Torpedo formosa sp. nov., a new species of electric ray (Chondrichthyes: Torpediniformes: Torpedinidae) from Taiwan

Zootaxa, 2006
A new species of torpedo ray, Torpedo formosa, sp. nov., is described from specimens collected from northeastern Taiwan. The new species is placed in the subgenus Tetronarce based on a uniform purplish dorsal coloration and the absence of papillae around the spiracles. It is distinct from the sympatric T.

Comparative genomics in Torpediniformes (Chondricthyes, Batoidea)

2011
Due of their basal position in the vertebrate phylogenetic tree, the study on Elasmobranch genetics and cytogenetics can provide interesting information on the evolution of all vertebrates. In recent years, different molecular approaches, among them the physical mapping of specific nucleotide sequences on chromosomes and the use of these genomic ...
