This study provides the first record of a juvenile Giant Devil Ray specimen and its metal and metalloid contents in Rio de Janeiro, Southeastern Brazil. A scientometric assessment was also conducted for the Manta and Mobula genera. A significant gap in knowledge on metal and metalloid ecotoxicology for mobulid rays was noted, pointing towards a new field of research for wildlife conservation and management.
This study comprises the first record of a juvenile Giant Devil Ray specimen for Rio de Janeiro, Southeastern Brazil, and its metal and metalloid contents. A scientometric assessment was also performed for the Manta and Mobula genera. Only five records were found, and only As, Cd, Pb, Hg, Pt, Pd and Rh have been assessed. All studies but one concerned human consumption. A significant knowledge gap on metal and metalloid ecotoxicology for mobulid rays is noted, indicating the emergence of a new field of research that th may be applied for wildlife conservation and management in response to anthropogenic contamination. Our study is also the first to provide Al, Cr, Cu, Fe, Mn, Sr, Ti, V and Zn contents for muscle, liver, brain and kidney for a mobulid ray and one of the scarce reports concerning As, Cd, Hg and Pb in muscle, liver and kidney.
