The skull of the leopard seal. The leopard seal has a distinctively long and muscular body shape when compared to other seals. The overall length of adults is 2.4–3.5 m (7.9–11.5 ft) and their weight is in the range 200 to 600 kilograms (440 to 1,320 lb), making them the same length as the northern walrus but usually less than half the weight.
These seals spend two-thirds of their time at sea. Monk seals spend much of their time foraging in deeper water outside of shallow lagoon reefs at sub-photic depths of 300 metres (160 fathoms) or more. [20] [21] Hawaiian monk seals breed and haul-out on sand, corals, and volcanic rock; sandy beaches are more commonly used for pupping. [13]
Brown fur seals prefer to haul-out and breed on rocky outcrops and small islands, rock ledges and exposed reefs, as well as on rocky, pebble or boulder beaches. However, some larger colonies can be found on sandy beaches, such as in South Africa. [3] Fur seals spend most of the year at-sea, but are never too far from land.
The seals frequently visit popular tourist beaches, often giving birth there, which creates a hazard for both the seal and the human, as mothers are aggressive and protective of their young.
Monk seals have a slender body and are agile. They have a broad, flat snout with nostrils on the top. Monk seals are polygynous, and group together in harems. They feed mainly on bony fish and cephalopods, but they are opportunistic. The skin is covered in small hairs, which are generally black in males and brown or dark gray in females.
