The stomach of a 10.2 m (34 ft) male sperm whale which became stranded at Rio Grande do Sul near Rio Grande, Brazil contained 227 upper cephalopod beaks and 255 lower cephalopod beaks. The lower beaks were identified and measured. Beaks of 14 species belonging to 9 families are present. Lower, rostral lengths are compared with those of the same species collected from stomachs of whales killed off South Africa and in the Antarctic. Estimates of the weight of flesh of the various species represented by beaks are made. Two ommastrephid species are estimated to contribute 33.1% of the weight of flesh represented by beaks while the octopoteuthids contribute 28.3% and the Onychoteuthids 18.5%. Three Antarctic species in the stomach show that the whale had migrated from south of Lat. 40°S prior to being caught and had not eaten much food during the journey which would probably have taken him more than 5 d.
