Abstract

Little work has been done on the smaller cetaceans of Tierra del Fuego. Data on strandings and new specimens for the following 14 species is presented: Lagenorhynchus australis, Cephalorhynchus commersonii, Lissodelphis peronii, Globicephala melaena, Orcinus orca, Phocoena spinipinnis, P. dioptrica, Tasmacetus shepherdi, Berardius arnuxii, Mesoplodon layardii, M. grayi, M. hectori, Ziphius cavirostris, and Hyperoodon planifrons. Area characteristics, exploitation and distribution are discussed. This study amplifies the known distribution of some species and increases the number of known specimens of others.
