A feeding association between Wilson's Storm-petrels Oceanites oceanicus (Kuhl, 1820) and Rough-toothed Dolphins Steno bredanensis (G. Cuvier in Lesson, 1828) Biota Neotropica
Olmos,Fábio; Rotenberg,Elsie; Muscat,Edelcio.
On 06 October 2012 a pod of Rough-toothed Dolphins Steno bredanensis (Delphinidae) was observed catching and tearing apart several Castin Leatherjacks Oligoplites saliens (Carangidae) near Montão de Trigo Island, northern coast of São Paulo, Brazil. The resulting floating masses of viscera attracted a feeding aggregation of 120-150 Wilson's Storm-petrels Oceanites oceanicus (Hydrobatidae), a transequatorial migrant passing through the area during October. This interspecific association has not been recorded before, although it could be expected given that S. bredanensis feeds on large fish and O. oceanicus is a known scavenger of kills made by cetaceans such as Killer Whales.

Santos,Marcos C. de O.; Laílson-Brito,José; Flach,Leonardo; Oshima,Júlia E. F.; Figueiredo,Giovanna C.; Carvalho,Rafael R.; Ventura,Elisa S.; Molina,Julia M. B.; Azevedo,Alexandre F..
Abstract: Cetaceans were monitored along ca. 700 km of the southeast coast of Brazil (22°S to 25°S) from 1995 to 2014 using photo-identification. The objective of this study was to identify any presence of long-distance movements for monitored cetacean species and discuss implications. Data on long-range movements of four of the monitored species are presented after the analysis of 321,765 photographs taken for individual identification. Seven individuals from four populations of Guiana dolphins (Sotalia guianensis) considered resident to particular estuaries or bays were reported in dispersal involving movement between pairs of protected areas over long-range distances varying between 86 and 135 km. Three cataloged rough-toothed dolphins (Steno...

Opportunistic feeding behaviour of rough-toothed dolphins Steno bredanensis off Mauritania Naturalis
Addink, M.J.; Smeenk, C..
A small group of rough-toothed dolphins Steno bredanensis was observed at the outer edge of the Banc d’Arguin, Mauritania. The animals were feeding opportunistically around a trawling research vessel. Hunting behaviour and mother-calf interactions are described
