“…Research on resource partitioning can broaden our understanding of species coexistence within the same geographic locations (Schoener, 1974), and there is evidence that ray species partition their resources (Barría et al., 2015; Belleggia, Scenna, Barbini, Figueroa, & Díaz De Astarloa, 2014; Bornatowski, Wosnick, Do Carmo, Corrêa, & Abilhoa, 2014; Espinoza, Munroe, Clarke, Fisk, & Wehrtmann, 2015; Every, Pethybridge, Fulton, Kyne, & Crook, 2017; Navarro‐González, Bohórquez‐Herrera, Navia, & Cruz‐Escalona, 2012; Pardo, Burgess, Teixeira, & Bennett, 2015; Plate ll, Potter, & Clarke, 1998; Rastgoo et al., 2018; Shibuya, Araújo, & Zuanon, 2009; Silva‐Garay, Pacheco, & Vélez‐Zuazo, 2018; Stewart et al., 2017; Treloar, Laurie, Laurenson, & Stevens, 2007; Yemışken et al., 2018; Yick, Tracey, & White, 2011). For example, in Peru, the pygmy devil ray ( Mobula munkiana , Mobulidae) had minimal isotopic niche overlap with three other devil ray species ( M. birostris , M. mobular and M. thurstoni ), which suggests that the pygmy devil ray may be feeding in a different area or on a different prey source than the other species (Stewart et al., 2017).…”
