Major threats to this species is incidental catches specifically by tuna fishermen in the eastern Pacific, and as sustainable by-catch with the use of gillnets in the Pacific and northern Indian Ocean (Ref. 85211). Spends the majority of their day nearshore, often between 90 to 300 m (Ref. 122680 but they also frequent oceanic waters (Ref. 801). They move further offshore at night into deeper waters to search for prey (Ref. 122680). Feeds largely on epipelagic fish and squid (Ref. 1394). It associates with parasites such as nematodes, cestodes, trematodes and acanthocephalans and commensals that includes cyamids amphipod, and barnacles (Ref. 85211). Social groups are formed by a range of a few individuals to thousands. It is composed of cow-calf pairs, adults and juveniles and they are grouped together or separately by juveniles or breeding groups. Their school size varies within the day (Ref. 85211).
