“…Additional data were obtained from the literature that cite, list or describe elasmobranch species off the Brazilian North coast: species available in the literature on bottom trawling (Pinheiro and Fredou 2004;Cintra et al 2015;Klautau et al 2016;Lutz et al 2016; see Table 1B); species recorded in taxonomic works (Lessa et al 1999;Almeida et al 2008; see Table 1C); species recorded in exploratory fishing work (Asano-Filho et al 2005, 2007Fredou and Asano-Filho 2006;Oliveira et al 2007; see Table 1D); and species recorded in molecular identification work (Carmona et al 2008;Rodrigues-Filho et al 2012;Palmeira et al 2013;Gemaque 2017;Silveira 2017;Feitosa et al 2018; see Table 1E).…”

“…Forty-eight elasmobranch species are currently recognized in the study area (see Lessa et al 1999;Santos et al 2004;Almeida et al 2008 ; Table 1C). Twenty-three species were also identified through the DNA barcoding of the (CO1) cytochrome oxidase-1 mitochondrial gene (Carmona et al 2008;Rodrigues-Filho et al 2012;Palmeira et al 2013;Silva,2016;Gemaque 2017;Silveira 2017;Feitosa et al 2018 ; Table 1E).

The Brazilian North coastline comprises a total area of approximately 223,000 km2, representing one of the world’s most essential fishing grounds. Availability of data on the diversity of fishes caught in the industrial fishery trawlers in the region are usually limited to the commercially important and targeted species. Knowledge gaps on the related marine fish fauna are eminent, which hamper both fisheries and conservation efforts of the local biodiversity. A comprehensive taxonomic list of elasmobranch species captured off the North coast from Brazil through industrial trawl fishery is provided. Trawling operations acting regionally included pink-shrimp and several fish (outrigger trawling) and piramutaba catfish (pair trawlers). Sixty-eigth elasmobranch species belonging to 20 families and nine orders were recorded for this region, according to fish collection, fishery observer and literature data. Thirty-two are by-catch species caught in the local trawl operations, including endemic and rare species as well as four new records and one possible undescribed species of electric ray.

“…Estimates of the diversification of the group based on DNA sequences are of the order of 300-460 million years ago. The class Chondrichthyes currently includes 14 orders and 60 families with approximately 1200 species [3][4][5]. The group of chondrichthyans with the greatest species diversity is the Batoidea (approximately 494 species), followed by the sharks, with around 500 species [4,5].…”

Chondrichthyes - Multidisciplinary Approach

The phylogenetic analysis of the Chondrichthyes has been the subject of intense debate over the past two decades. The principal relationships within the group based on the analysis of morphological traits are inconsistent with the available molecular topologies, and the phylogeny of these animals is highly controversial, at all levels, ranging from superorders to families and even the genera within families. With the recent development of new generation sequencing (NGS), many phylogenies are now being inferred based on the complete genome of the species. In 2015 and 2016 alone, around 21 new elasmobranch genomes were made available in GenBank. In this context, the principal objective of the present study was to infer the phylogeny of the sharks and rays based on the complete mitochondrial genomes available in the literature. A total of 73 mitogenomes of chondrichthyan species were analyzed. The phylogenetic trees generated rejected the "Hypnosqualea" hypothesis and confirmed the monophyly of the Neoselachii and Batoidea as sister groups of the sharks. These mitogenomic analyses provided ampler and more complete insights into the relationships between the sharks and rays, in particular, the topologies obtained by the analyses revealed a number of incongruities in certain groups of sharks and rays, and the interrelationships between them.

“…These problems are exacerbated by the lack of data on the diversity of the elasmobranch fauna of many regions of the world [56,57]. In recent years, there have been considerable eforts in the Asian region, with wide-ranging phylogenetic and morphological inferences [5,6], as well as the description of new species [7,11,15] and the reinstatement of a number of families [8].…”
