  abstract = {{U}sing a combination of diverse large predatory fishes and one seabird, we collected information on the cephalopod fauna of the western {I}ndian {O}cean. {W}e analyzed the stomach contents of 35 fishes representing ten families ({X}iphiidae, {I}stiophoridae, {S}combridae, {C}arangidae, {C}oryphaenidae, {A}lepisauridae, {D}asyatidae, {C}archarhinidae, {A}lopiidae and {S}phyrnidae) and of the sooty tern {O}nychoprion fuscata of the {M}ozambique {C}hannel from 2000 to 2010. {B}oth fresh and accumulated beaks were used for identifying cephalopod prey. {C}ephalopods were important prey for twelve predators; swordfish {X}iphias gladius had the highest cephalopod proportion; sooty tern ({O}. fuscata) and bigeye tuna ({T}hunnus obesus) had high proportions too. {W}e recovered 23 cephalopod families and identified 38 species. {T}en species from four {T}euthida families ({O}mmastrephidae, {O}nychoteuthidae, {H}istioteuthidae and {A}ncistrocheiridae) and two {O}ctopoda families ({A}rgonautidae and {B}olitaenidae) occurred very frequently in the stomach contents, while {S}epiida were rare. {O}mmastrephidae were the most cephalopod food sources: the purpleback flying squid {S}thenoteu this oualaniensis was the most prevalent prey by far, {O}rnithoteuthis volatilis was important for eleven predators and few but large specimens of the neon flying squid {O}mmastrephes bartramii were recovered in the stomachs of swordfish in the {I}ndian {S}outh {S}ubtropical {G}yre province only. {P}redators' groups were identified based on cephalopod prey composition, on depth in which they forage, and on prey size. {S}urface predators' diets were characterized by lower cephalopod diversity but greater average numbers of cephalopod prey, whereas the deep-dwelling predators (swordfish and bigeye tuna) preyed on larger specimens than surface predators ({O}. fuscata or yellowfin tunas {T}hunnus albacares). {O}ur findings emphasized the usefulness of a community of marine predators to gain valuable information on the biology and the distribution of the cephalopod forage fauna that are discussed with regard to biogeographic province, marine predator, fishing gear to catch the large pelagic fishes, and size of the beaks recovered in the stomachs.},
