It is an area of high productivity and great biodiversity in waters of the Province of Chubut. Thirteen of Argentina's 16 resident seabird species breed in this area which is also home to the largest colony of the South American fur seal. Invertebrates and fish both spawn in the Golfo San Jorge and it is therefore important as a foraging area for seabirds and marine mammals.
