During the austral summer of 2001 we studied the distribution and population size of southern sea lion Otaria flavescens (Shaw 1800) and south american fur seal Arctocephalus australis (Zimmermann 1783), in the Twelfth region of Chile (Magellan region). During our study 2,606 sea lions and 20,168 fur seals were counted. Comparison with the few available census data collected prior to our study suggests an important population decrease for both species with respect to estimations undertaken during the 1970s.
