Preliminary analysis of the feeding habits of batoids from the genera Mobula and Myliobatis in Northern Peru

Abstract: This study provides baseline information on the feeding habits of five batoid species from the genera Mobula and Myliobatis sampled from the small-scale driftnet fishery in northern Peru. The diets of Mobula mobular, Mobula munkiana and Mobula thurstoni consisted mainly of euphausiids. Die...
