Multi-marker metabarcoding data for dietary analysis of elasmobranchs
This study aims to characterize the diet of three threatened elasmobranch species (Pseudobatos percellens, Carcharhinus oxyrhynchus and Pristis pristis)from the Brazilian Amazon Coast region using a multi-marker metabarcoding approach. By analyzing stomach contents from fisheries bycatch with COXI, 12S rRNA and 16S rRNA markers, the data contribute to understanding feeding ecology and trophic roles of elasmobranchs in a poorly studied biodiversity hotspot, supporting conservation and future comparative studies.
