... Sociality facilitates foraging success in a wide range of animals, both in captivity (Grand & Dill, 1999;Harpaz & Schneidman, 2020;Krebs et al., 1972;Pitcher et al., 1982), and in the wild (Morand-Ferron & Quinn, 2011;Snijders et al., 2021). On an individual level, more social guppies (Poecilia reticulata) and great tits (Parus major) with more central network positions visited more novel food patches (Aplin et al., 2012;Snijders et al., 2018Snijders et al., , 2019, while more social three-spined sticklebacks (Gasterosteus aculeatus) experienced less food intake variance (Jolles et al., 2017). ...

... Moreover, that striped marlin regularly shifted depth patterns across time and location demonstrated adaptive use of the water column, likely in response to local foraging opportunities. Considering that striped marlin are known to rush at a sardine school near the sea surface (Hansen et al., 2020), they might use the same hunting strategy at boundary conditions, namely at the top of and in the thermocline and oxycline (Lam et al., 2015) to exploit a diverse selection of prey (Abitia-Caŕdenas et al., 1997;Shimose et al., 2010;Ortega Garcia et al., 2017). This would reduce competition with other top predators through trophic niche separation (Acosta-Pachoń and Ortega-Garcıá, 2019;Rosas-Luis et al., 2021). ...
