Editing Angelshark (section)

==Species analysis==
Morphological identification in the field can be difficult due to discontinuity and similarity of species. In this specific circumstance, the sharks' place within the genus ''Squatina'' comprises three species in the southern part of the western Atlantic. The three species observed were ''Squatina guggenheim'', ''S.&nbsp;occulta'' and the Brazilian guitarfish ''Pseudobatos horkelii''. These three species are listed in the IUCN Red List as threatened, and they are  now protected under Brazilian law, which makes angling and exchange illegal. To prevent landing and trade of these endangered species along the São Paulo, DNA barcoding was used. DNA barcoding revealed fishing and trafficking of these protected species.<ref name="Bunholi et al 2018">{{cite journal |last1=Bunholi |first1=Ingrid Vasconcellos |last2=Ferrette |first2=Bruno Lopes da Silva |last3=De Biasi |first3=Juliana Beltramin |last4=Magalhães |first4=Carolina de Oliveira |last5=Rotundo |first5=Matheus Marcos |last6=Oliveira |first6=Claudio |last7=Foresti |first7=Fausto |last8=Mendonça |first8=Fernando Fernandes |title=The fishing and illegal trade of the angelshark: DNA barcoding against misleading identifications |journal=Fisheries Research |date=October 2018 |volume=206 |pages=193–197 |doi=10.1016/j.fishres.2018.05.018|hdl=11449/166239 |s2cid=90620208 |url=https://repositorio.unesp.br/bitstream/11449/166239/1/WOS000438005100019.pdf |hdl-access=free }}</ref> <!-- original research Subatomic hereditary apparatuses are presently used for commonsense ordered recognizable proof, especially in situations where morphological perception is forestalled, e.g., amid fish handling. Thus, DNA barcoding was used in the present examination to track potential errors against the arrival and exchange of imperiled species along the São Paulo coastline, specifically ''Squatina guggenheim'' (n = 75) and'' S. occulta'' (n = 5), and also the Brazilian guitarfish'' Pseudobatos horkelii'' (n = 5). DNA barcoding uncovered ceaseless angling and trafficking of these ensured species, subsequently giving clear proof that the present protection models and strategies for observing are not working.<ref name="Bunholi et al 2018"/>
