Habitat
Antarctic fur seals primarily inhabit sub-Antarctic islands such as South Georgia and the South Shetland Islands, favoring rocky beaches and coastal areas for breeding and resting. They spend most of their time in cold, nutrient-rich marine waters, often venturing into open ocean for foraging.
Diet
Antarctic fur seals mainly eat krill, fish like lanternfish, and squid, which they hunt by diving to depths of up to 200 meters. They are opportunistic feeders, often targeting schools of prey during dawn and dusk, and use their whiskers to detect food in low-light conditions.
Behavior
Antarctic fur seals are highly social, forming large breeding colonies on beaches where males establish and defend territories during the mating season. They are agile swimmers, spending much of their time at sea hunting, but on land they are often seen basking or interacting with others. Females form strong bonds with their pups, nursing them for several months, and the species exhibits playful behaviors like porpoising through waves.
Conservation Status
The IUCN classifies the Antarctic fur seal as Least Concern, with populations having recovered from historical hunting and now stable or increasing. Major threats include climate change affecting sea ice and prey availability, as well as incidental bycatch in fisheries.
