Aquatic Mammals (2002)


The northernmost records of four cold-water cetacean species in the southwestern Atlantic are presented: the spectacled porpoise (Phocoena dioptrica), Layard’s beaked whale (Mesoplodon layardii), Commerson’s dolphin (Cephalorhynchus commersonii), and Peale’s dolphin (Lagenorhynchus australis). These records were represented by four strandings along the southern Brazilian coast (31° to 32°S) from 1994 to 1999. Previous northernmost records were for Uruguay and Argentina. External and skull measurements, together with information on ingested food and gastrointestinal parasites are provided.
