“…There are few studies addressing the anomalies in Elasmobranchii, however the cases have been gradually increasing. Dicephaly, cephalic malformation and albinism are some published reports for sharks (5,6,7,8). Little is known about the reasons that could lead to these deformities and further research is needed leading to a better understanding of the cases.…”

“…El albinismo ha sido reportado en el grupo de los condrictios, tanto en los tiburones como en las rayas y en una sola especie de quimera (Ben-Souissi et al 2007;Reum et al 2008;Bigman et al 2015), aunque es un fenómeno menos frecuente en comparación con los peces óseos (Wakida-Kusunoki, 2015). En el Pacífico oriental ha sido documentado el albinismo en diferentes especies de condrictios (Herald, 1953;Herald et al 1960;Cohen, 1973;Talent, 1973;Follett, 1976;Ebert, 1985;De Jesús-Roldan, 1990;Sandoval-Castillo et al 2006;Reum et al 2008;Bejarano-Ál-varez & Galván-Magaña, 2013;Escobar-Sánchez et al 2014;Bigman et al 2015;Sancho-Vázquez et al 2015), sin embargo, aún no se ha reportado para la familia Urotrygonidae. La familia está representada hasta el momento por 18 especies y se distribuyen en las aguas tropicales de ambas costas del continente americano (Eschmeyer & Fong, 2016).…”

La familia está representada hasta el momento por 18 especies y se distribuyen en las aguas tropicales de ambas costas del continente americano (Eschmeyer & Fong, 2016). Se caracterizan por tener un tamaño de pequeño a moderado (16-80 cm), el ancho del disco no más que 1.3 veces el largo, aletas pectorales continuas y fusionadas, sin presencia de aletas dorsales, morro de redondeado a puntiagudo, habitan en mares tropicales y templados, pocas especies alcanzan profundidades mayores a los 100 m (Nelson et al 2016).…”

“…Several morphological abnormalities have been reported in sharks (Subclass: Selachii) in different marine ecoregions around the world. This reports include albinism (e.g., Clark, 2002;Saïdi et al, 2006;Bottaro et al, 2008;Escobar-Sánchez et al, 2014), bicephaly (e.g., Galván-Magaña et al, 2011;Wagner et al, 2013), diprosopia (e.g., Mancini et al, 2006;Hevia-Hormazábal et al, 2011;Driggers et al, 2012), deformities in axial skeleton (e.g., Pastore & Prato, 1989;Heupel et al, 1999;Mancini et al, 2006), mummification (e.g., Rosa-Molinar et al, 1983;Sandoval-Castillo & Villavicencio-Garay-Zar, 2008) and even cyclopia (Bejarano-Álvarez & Galván-Magaña, 2013). Blue shark (Prionace glauca) is the shark species with the highest number of anomalies reported, which have been described by different authors (e.g., Goto et al, 1981;Mancini et al, 2006;Galván-Magaña et al, 2011;Hevia-Hormazábal et al, 2011;Bejarano-Álvarez et al, 2013;Ehemann et al, 2016;Rodríguez-Romero et al, 2018;Ramírez-Amaro et al, 2019).…”
