Geographic and ontogenetic variation in the diet of two commonly exploited batoids (Chilean eagle ray and Pacific guitarfish) off Peru: evidence of trophic plasticity

This study provides information about the diet across geographic areas and throughout ontogeny and sex of two coastal and commercial batoid species in Peru (Chilean eagle ray Myliobatis chilensis and Pacific guitarfish Pseudobatos planiceps ). Data was collected in the central coast (13°30′S to 14°3...
