%X stomach contents of seven cartilaginous fish species were analysed with the aim to detect trophic groups. sampling was effectuated between october/85 and july/87 off the coast of ubatuba (s£¿o paulo, brazil) in waters up 50 m depth. the relative importance of different components of the diet was expressed as a percentage frequency of occurrence and percentage number. the seven species were grouped in: fish feeders - squalus cubensis; benthonic crustacean and fish feeders - raja castelnaui, raja cyclophora, raja agassizi; benthonic invertebrate feeders - rhinobatos horkelii, zapteryx brevirostris, psammobatis glansdissimilis.
