Defenders provides you with our co-sponsored newly-published book on Freshwater rays (Potamotrygonidae), where you will find exquisite details of the latest research from Carlos Lasso (Humboldt Institute from Colombia) on these magnificent and forgotten species in the mega-diverse countries of South America. Freshwater rays have been a topic of discussion in CITES since 2004 and, in 2016, Colombia and Brazil listed some species of the Family in Appendix III.
