Arctocephalinae, commonly known as fur seals, are marine mammals found in the Southern Hemisphere. They are characterized by their thick, insulating fur, long whiskers, and agile swimming capabilities. These social creatures often form large colonies on rocky coastlines and are known for their playful behavior and vocal communication.

Arctocephalinae, commonly known as fur seals, are primarily found in the Southern Hemisphere. Their geographical distribution includes regions such as the coasts of South America, Australia, New Zealand, and various sub-Antarctic islands. Some species are also found in the Northern Hemisphere, particularly in the northern Pacific Ocean, including areas around the Bering Sea and the coasts of Alaska and Russia.

Fur seals typically inhabit coastal waters and islands. They prefer rocky shores and beaches that provide easy access to the ocean for feeding. The climate in these regions varies significantly, ranging from temperate to sub-Antarctic conditions. The Southern Hemisphere populations often experience cold oceanic climates with cold, nutrient-rich waters due to ocean currents like the Antarctic Circumpolar Current.

Fur seals are marine mammals that occupy the ecological niche of a mid-level predator in the marine ecosystem. They primarily feed on fish and squid, making them important consumers in the marine food web. Their presence helps regulate the populations of their prey species, contributing to the balance of the marine ecosystem. Variations in their habitat and diet can occur based on regional availability of prey and environmental conditions.
