Abstract

OTT, Paulo H et al. Evidences of attack of a killer whale on a calf southern right whale in southern Brazil. Mastozool. neotrop. [online]. 2017, vol.24, n.1, pp.235-240. ISSN 0327-9383.

The killer whale (Orcinus orca) has a worldwide distribution and its feeding habits varies greatly among populations. In the southern Atlantic Ocean, knowledge about the distribution and diet of the species is still scarce. Herein we report the first evidence of a killer whale’s attack on a southern right whale (Eubalaena australis) in Brazilian waters and provide new records of killer whale sightings in coastal waters of the southernmost Brazilian region.

Keywords : Eubalaena australis; Orcinus orca; Predatory-prey interaction; Stranding; Tooth marks.
