Description
The brown fur seal is the largest and most robust member of the southern fur seals. It has a large and broad head with a pointed snout that may be flat or turned up slightly. They have external ear flaps (pinnae) and their whiskers (vibrissae) are long, and may extend backward past the pinnae, especially in adult males. The fore flippers are covered with sparse hair over about three-quarters of their length. The hind flippers are short relative to the large body, with short, fleshy tips on the digits. The size and weight of the brown fur seal depends on the subspecies. The Southern African subspecies is on average slightly larger than the Australian subspecies. Males of the African subspecies (A. p. pusillus) are 2.3 m (7.5 ft) in length on average and weigh 200–300 kg (440–660 lb). Females are smaller, averaging 1.8 m (5.9 ft) in length and typically weighing 120 kg (260 lb). Males of the Australian subspecies (A. p. doriferus) are 2.0–2.2 m (6.6–7.2 ft) in length and weigh 190–280 kg (420–620 lb). Females are 1.2–1.8 m (3.9–5.9 ft) length and weigh 36–110 kilograms (79–243 lb). Adult male brown fur seals are dark gray to brown, with a darker mane of short, coarse hairs and a light belly, while adult females are light brown to gray, with a light throat and darker back and belly. The fore flippers of the fur seal are dark brown to black. Pups are born black and molt to gray with a pale throat within 3-5 months. The skull of the African subspecies has a larger crest between the mastoid process and the jugular process of the exoccipital.

Diet
The primary food for brown fur seal is fish, with a strong preference for small, schooling species. Their diet is rich in anchovies, sardines, and to a lesser extent, squids. This species dives to considerable depths to forage for food.
Appearance
Brown fur seal is a medium-sized marine animal with a sleek, robust body covered in thick, short fur. Primarily dark brown to black, males often have a mane of longer, darker fur. Their faces are pointed with external ear flaps and vibrissae around their snouts. Notably, males have a larger body size and pronounced sagittal crest compared to females. Pups are born with black fur that lightens as they age.
Behavior
Brown fur seal exhibits sophisticated social behavior, forming large colonies on land while navigating independently at sea. They demonstrate pronounced sexual dimorphism and polygyny. Brown fur seal's unique survival habits include foraging offshore, often diving to depths of 200m in search of prey.
