- Diet of the chola guitarfish, Rhinobatos percellens (Rhinobatidae), in the Paranaguá Estuarine complex WANESSA P.D. DO CARMO HUGO BORNATOWSKI ELTON C. OLIVEIRA LUÍS L. FÁVARO Multidisciplinaria (Ciencias Naturales y Exactas) diet Caridea estuary especialist Rhinobatidae The chola guitarfish, Rhinobatos percellens , is one of the most-captured batoids on the Brazilian coast, and an important predator of benthic community. Stomachs from R. percellens were sampled in the Paranaguá estuarine complex (March/2006 to March/2007 and October/2008 to September/2009). The stomachs obtained were used for describing the diet of R. percellens , and verifying if there are seasonal and ontogenetic differences in their feeding into the estuarine area. The general analysis showed a specialized diet with a predominance of three species in food contents: Leptochela serratorbita , Caridea remains and Ogyrides alphaerostris . Ontogenetic and seasonal analysis did not reveal significant differences in the food consumption. These data reveal that R. percellens is a specialist predator of L. serratorbita , and this food component is consumed by all size classes. 2015 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32739721013 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.87
