Abstract

The interaction between baleen whales and longline fisheries is poorly known worldwide and likely underestimated. This article presents one of the most severe scenarios of this interaction; an incident that resulted in the severe mutilation of the entire fluke of a whale and probably lead to its death. Considering the characteristic of the fluke, we strongly suggest that the fluke belonged to a small balaenopterid, most likely a dwarf minke whale (Balaenoptera acutorostrata). The episode reported here seems to be the first in its nature involving a baleen whale entangled in longline fishing gear off the Brazilian coast, and so, it represents, at the very least, the need for further investigation into the magnitude of such interactions in the south-west Atlantic Ocean.
