Biology     Glossary (e.g. epibenthic)

Feeds largely on epipelagic fish and squid (Ref. 1394). Depth range based on reported depth in Angola (Ref. 83346). 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). 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).
