  abstract = {{B}lue shark ({P}rionace glauca) is amongst the most abundant shark species in international trade, however this highly migratory species has little effective management and the need for spatio-temporal strategies increases, possibly involving the most vulnerable stage or sex classes. {W}e combined 265,595 blue shark observations (capture or satellite tag) with environmental data to present the first global-scale analysis of species' habitat preferences for five size and sex classes (small juveniles, large juvenile males and females, adult males and females). {W}e leveraged the understanding of blue shark biotic environmental associations to develop two indicators of foraging location: productivity fronts in mesotrophic areas and mesopelagic micronekton in oligotrophic environments. {T}emperature (at surface and mixed layer depth plus 100 m) and sea surface height anomaly were used to exclude unsuitable abiotic environments. {T}o capture the horizontal and vertical extent of thermal habitat for the blue shark, we defined the temperature niche relative to both sea surface temperature ({SST}) and the temperature 100 m below the mixed layer depth ({T}mld+100). {W}e show that the lifetime foraging niche incorporates highly diverse biotic and abiotic conditions: the blue shark tends to shift from mesotrophic and temperate surface waters during juvenile stages to more oligotrophic and warm surface waters for adults. {H}owever, low productivity limits all classes of blue shark habitat in the tropical western {N}orth {A}tlantic, and both low productivity and warm temperatures limit habitat in most of the equatorial {I}ndian {O}cean (except for the adult males) and tropical eastern {P}acific. {L}arge females tend to have greater habitat overlap with small juveniles than large males, more defined by temperature than productivity preferences. {I}n particular, large juvenile females tend to extend their range into higher latitudes than large males, likely due to greater tolerance to relatively cold waters. {L}arge juvenile and adult females also seem to avoid areas with intermediate {SST} (similar to 21.7-24.0 degrees {C}), resulting in separation from large males mostly in the tropical and temperate latitudes in the cold and warm seasons, respectively. {T}he habitat requirements of sensitive size- and sex-specific stages to blue shark population dynamics are essential in management to improve conservation of this near-threatened species.},
