A PRELIMINARY SURVEY ON THE STATUS OF

ABSTRACT. New data on the distribution of the Neotropical river otter (Lontra longicaudis) as well as new records of the giant otter (Pteronura brasiliensis) in Uruguay are provided. The information presented was gathered from otter sighting surveys completed by Uruguayan researchers, wildlife technicians and environmentalists. New localities for both species, comments on the behaviour and data about the habitats used by the Neotropical river otter were obtained. The information about distribution was completed by an examination of records from zoological collections and literature. This survey confirms that the Neotropical river otter is at least fairly common in Uruguay. The conservation status of the giant otter is uncertain. Although considered extirpated for many years, a recent sighting of two individuals has been reported. This information has to be confirmed
