The Antarctic fur seal's ability to prop itself up into a standing position upon its front flippers is one of its distinguishing characteristics. Most pups are born black in color, eventually turn silver-gray, and then gradually become brown as an adult. Some seals have lighter-colored fur. It has a lifespan of approximately 15 to 20 years. Adult females are approximately 1.2-1.4 meters (3.9-4.6 feet) in length and weigh 25-55 kilograms (55-121 pounds), adult males are approximately 1.6-2.0 meters (5.2-6.6 feet) in length and weigh 90-210 kilograms (198-463 pounds).
The Antarctic fur seal lives in the Antarctic Ocean, and comes ashore to reproduce. The seals reproduce on islands which are free of ice, located along the Antarctic Polar Front. The majority of the species reproduces along the coasts of the island of South Georgia. However, the species has a wide range and has been observed as far away as Brazil.
Male seals are approximately four times larger than the females, and are extremely territorial.
Antarctic fur seals subsist primarily on a diet of krill, fish, and squid. They have been known to consume sea birds, and nursing females almost exclusively eat krill. Predators of Antarctic fur seals include orcas, leopard seals, and humans. The primary danger from people comes in the form of entanglement when man-made debris becomes wrapped around the neck of the seal, and it strangles or drowns.
In the early 1900s, the species was nearly extinct. There were only a few hundred Antarctic fur seals left due to massive over-hunting by people. Thanks to protective legislation, the population has rebounded, and by some estimates may have reached four or five million in the year 2000.
Antarctic fur seals are protected by the Convention for the Conservation of Antarctic Seals (CCAS), the Antarctic Treaty, and the national legislation of countries within its habitat. It is listed as an Appendix II species by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
