The sessile barnacleXenobalanus globicipitiswas observed on multiple cetacean species during field surveys off the northern coast of Sao Paulo state, Brazil. However, the occurrence ofX. globicipitisin cetaceans in Brazilian waters has been, up to now, scarce. In the present study, this epibiont is reported for the first time in orcas (Orcinus orca), rough-toothed dolphins (Steno bredanensis) and Atlantic spotted dolphins (Stenella frontalis) from south-eastern Brazil. Guiana dolphins (Sotalia guianensis) and common bottlenose dolphins (Tursiops truncatus) have also been infested. This is the first world record ofX. globicipitisinBalaenoptera brydeiandStenella frontalis. All records were photographed and may reveal changes in this barnacle's settlement in 2018 and 2019. The possible causes for these infestations are discussed, including anthropogenic activities and recent oceanic events.
