OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig.

Prior to diving, phocid (true) seals generally exhale, a behaviour thought to assist with prevention of decompression sickness. Otariid seals (fur seals and sea lions) have a greater reliance on their lung oxygen stores, and inhale prior to diving.

Aside from the overall large size of adults and generally robust build of all age and sex classes, the most conspicuous characteristics are the appear- ance of the head and muzzle, which are mas- sive and wide. The eyes and ear pinnae appear small when compared with the size of the rest FEMALE of the head. The vibrissae can be very long in adults. In all but adult males, there is little or no clear demarcation between the crown of the MALE DORSAL VIEW head and the muzzle, thus no forehead. In adult males, development of the sagittal crest produces a variable amount of forehead demar- cating the muzzle and crown. Breeding bulls in their prime are very robust in the neck and shoulder area and have a mane of longer guard hairs. Both the fore- and hindflippers are very long and broad for an otariid. Collectively, FEMALE these features make the upper body appear massive in relation to the lower body. MALE Coloration in adults is pale yellow to light tan VENTRAL VIEW above, darkening to brown and shading to rust below. Unlike most pinnipeds, when wet, Stel- ler sea lions are paler, appearing greyish white. Pups are born with a thick blackish brown lanugo that is moulted by about 6 months of age.

Variability in Haul-Out Behaviour by Male Australian Sea Lions Neophoca Cinerea in the Perth Metropolitan Area, Western Australia
Vol. 28: 259–274, 2015 ENDANGERED SPECIES RESEARCH Published online October 20 doi: 10.3354/esr00690 Endang Species Res OPEN ACCESS Variability in haul-out behaviour by male Australian sea lions Neophoca cinerea in the Perth metropolitan area, Western Australia Sylvia K. Osterrieder1,2,*, Chandra Salgado Kent1, Randall W. Robinson2 1Centre for Marine Science and Technology, Curtin University, Bentley, Western Australia 6102, Australia 2Institute for Sustainability and Innovation, College of Engineering and Science, Victoria University, Footscray Park, Victoria 3011, Australia ABSTRACT: Pinnipeds spend significant time hauled out, and their haul-out behaviour can be dependent on environment and life stage. In Western Australia, male Australian sea lions Neo - phoca cinerea haul out on Perth metropolitan islands, with numbers peaking during aseasonal (~17.4 mo in duration), non-breeding periods. Little is known about daily haul-out patterns and their association with environmental conditions. Such detail is necessary to accurately monitor behavioural patterns and local abundance, ultimately improving long-term conservation manage- ment, particularly where, due to lack of availability, typical pup counts are infeasible. Hourly counts of N. cinerea were conducted from 08:00 to 16:00 h on Seal and Carnac Islands for 166 d over 2 yr, including 2 peak periods. Generalised additive models were used to determine effects of temporal and environmental factors on N. cinerea haul-out numbers. On Seal Island, numbers increased significantly throughout the day during both peak periods, but only did so in the second peak on Carnac. During non-peak periods there were no significant daytime changes. Despite high day-to-day variation, a greater and more stable number of N.
