Molecular and Chromosomal Markers for Evolutionary Considerations in Torpediniformes (Chondrichthyes, Batoidea) [PDF]
ISRN Genetics, 2013 Due to their basal position in the vertebrate phylogenetic tree, the study on elasmobranch genetics and cytogenetics can provide remarkable information on the mechanisms underlying the evolution of all vertebrates. In recent years, different molecular approaches have been used to study the relationships between the different taxonomic groups of ...

Journal of Morphology, 2021
Abstract Torpediniformes (electric rays) is a monophyletic group strongly supported by morphological and molecular phylogenetic studies. The claspers of electric rays, however, are poorly documented in comparation to the clasper of other batoids, especially skates, and the knowledge of their anatomical variation is restricted to the ...

Mitogenomics of electric rays: evolutionary considerations within Torpediniformes (Batoidea; Chondrichthyes) [PDF]
Zoological Journal of the Linnean Society, 2016 Torpediniformes (electric rays) is a relatively diverse group of benthic coastal elasmobranchs found in all shallow tropical to temperate waters around the world. Despite its ecological and evolutionary importance, the inter-relationships within this lineage of cartilaginous fishes and its phylogenetic position within Batoidea remain controversial.

Latin American Journal of Aquatic Research, 2010 Se analizaron aspectos reproductivos de la raya eléctrica Narcine bancroftii, capturada como bycatch con una red playera de cerco en dos playas del sector de El Rodadero, Santa Marta, Caribe colombiano. Los ejemplares fueron sexados, pesados y medidos, se identificó su estado de desarrollo gonadal mediante características morfológicas externas e ...

Zoology, 2021 Despite being commonly recognized by the general public, knowledge about the biology and life-history of electric rays is still scarce. Globally, according to the International Union for Conservation of Nature, more of the 80% of the species belonging to the Torpedinidae family are, indeed, classified as Data Deficient, so as, in most of the cases, no ...

First records of the leopard electric ray Narcine leoparda (Torpediniformes: Narcinidae) in the Ecuadorian Pacific [PDF]
Revista De Biologia Marina Y Oceanografia, 2015 The aim of this study was to report the presence of the leopard electric ray Narcine leoparda in Ecuadorian waters; to date, this is the southernmost report of this species in the Tropical Eastern Pacific. Thus, the geographic distribution of N. leoparda now extends another ca., 620 km from Cauca, Colombia (previous southernmost limit of this species ...
