Synonyms: Arctocephalus australis australis; Arctocephalus australis gracilis

Wikipedia Abstract

The South American fur seal (Arctocephalus australis) breeds on the coasts of Chile, Peru, and Argentina. The total population is around 250,000.The population of South American fur seals in 1999 was estimated at 390,000, a drop from a 1987 estimate of 500,000. Although overall species numbers are healthy, the downward trend is causing some concern. Uruguay has the largest numbers of seals along its coast, numbering over 200,000.
