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. -

Deal Island an Historical Overview
Introduction. In June 1840 the Port Officer of Hobart Captain W. Moriarty wrote to the Governor of Van Diemen’s Land, Sir John Franklin suggesting that lighthouses should be erected in Bass Strait. On February 3rd. 1841 Sir John Franklin wrote to Sir George Gipps, Governor of New South Wales seeking his co-operation. Government House, Van Diemen’s Land. 3rd. February 1841 My Dear Sir George. ………………….This matter has occupied much of my attention since my arrival in the Colony, and recent ocurances in Bass Strait have given increased importance to the subject, within the four years of my residence here, two large barques have been entirely wrecked there, a third stranded a brig lost with all her crew, besides two or three colonial schooners, whose passengers and crew shared the same fate, not to mention the recent loss of the Clonmell steamer, the prevalence of strong winds, the uncertainty of either the set or force of the currents, the number of small rocks, islets and shoals, which though they appear on the chart, have but been imperfectly surveyed, combine to render Bass Strait under any circumstances an anxious passage for seamen to enter. The Legislative Council, Votes and Proceedings between 1841 – 42 had much correspondence on the viability of erecting lighthouses in Bass Strait including Deal Island. In 1846 construction of the lightstation began on Deal Island with the lighthouse completed in February 1848. The first keeper William Baudinet, his wife and seven children arriving on the island in March 1848. From 1816 to 1961 about 18 recorded shipwrecks have occurred in the vicinity of Deal Island, with the Bulli (1877) and the Karitane (1921) the most well known of these shipwrecks. -
Overview of Tasmania's Offshore Islands and Their Role in Nature
Papers and Proceedings of the Royal Society of Tasmania, Volume 154, 2020 83 OVERVIEW OF TASMANIA’S OFFSHORE ISLANDS AND THEIR ROLE IN NATURE CONSERVATION by Sally L. Bryant and Stephen Harris (with one text-figure, two tables, eight plates and two appendices) Bryant, S.L. & Harris, S. 2020 (9:xii): Overview of Tasmania’s offshore islands and their role in nature conservation.Papers and Proceedings of the Royal Society of Tasmania 154: 83–106. https://doi.org/10.26749/rstpp.154.83 ISSN: 0080–4703. Tasmanian Land Conservancy, PO Box 2112, Lower Sandy Bay, Tasmania 7005, Australia (SLB*); Department of Archaeology and Natural History, College of Asia and the Pacific, Australian National University, Canberra, ACT 2601 (SH). *Author for correspondence: Email: [email protected] Since the 1970s, knowledge of Tasmania’s offshore islands has expanded greatly due to an increase in systematic and regional surveys, the continuation of several long-term monitoring programs and the improved delivery of pest management and translocation programs. However, many islands remain data-poor especially for invertebrate fauna, and non-vascular flora, and information sources are dispersed across numerous platforms. While more than 90% of Tasmania’s offshore islands are statutory reserves, many are impacted by a range of disturbances, particularly invasive species with no decision-making framework in place to prioritise their management. This paper synthesises the significant contribution offshore islands make to Tasmania’s land-based natural assets and identifies gaps and deficiencies hampering their protection. A continuing focus on detailed gap-filling surveys aided by partnership restoration programs and collaborative national forums must be strengthened if we are to capitalise on the conservation benefits islands provide in the face of rapidly changing environmental conditions and pressure for future use. -

Impact of Rising Sea Levels on Australian Fur Seals
Impact of rising sea levels on Australian fur seals Lachlan J. McLean1, Steve George2, Daniel Ierodiaconou3, Roger J. Kirkwood4 and John P.Y. Arnould1 1 School of Life and Environmental Sciences, Deakin University, Burwood, Victoria, Australia 2 National Centre for Atmospheric Science-Climate, University of Reading, Reading, United Kingdom 3 School of Life and Environmental Sciences, Deakin University, Warrnambool, Victoria, Australia 4 Research Department, Phillip Island Nature Parks, Cowes, Victoria, Australia ABSTRACT Global warming is leading to many unprecedented changes in the ocean-climate system. Sea levels are rising at an increasing rate and are amplifying the impact of storm surges along coastlines. As variability in the timing and strength of storm surges has been shown to affect pup mortality in the Australian fur seal (Arctocephalus pusillus doriferus), there is a need to identify the potential impacts of increased sea level and storm surges on the breeding areas of this important marine predator in Bass Strait, south-eastern Australia. Using high-resolution aerial photography and topographic data, the present study assessed the impacts of future inundation levels on both current and potential breeding habitats at each colony. Inundation from storm surges, based on a predicted rise in sea level, was modeled at each colony from 2012 to 2100. As sea level increases, progressively less severe storm surge conditions will be required to exceed current inundation levels and, thus, have the potential for greater impacts on pup mortality at Australian fur seal colonies. The results of the present study indicate that by 2100, a 1-in-10 year storm will inundate more habitat on average than a present- day 1-in-100 year storm. -

Regional Classification of Tasmanian Coastal Waters
REGIONAL CLASSIFICATION OF TASMANIAN COASTAL WATERS AND PRELIMINARY IDENTIFICATION OF REPRESENTATIVE MARINE PROTECTED AREA SITES G.J. Edgar, J. Moverley, D. Peters and C. Reed Ocean Rescue 2000 - Marine Protected Area Program 1993/94 Project No. D705 Report to: Australian Nature Conservation Authority From: Parks and Wildlife Service, Department of Environment & Land Management 134 Macquarie St, Hobart, Tasmania 1 EXECUTIVE SUMMARY Analysis of the distribution of reef plants and animals at over 150 sites around the Tasmanian coastline and Bass Strait islands indicated that Bass Strait reef communities were distinctly different from those occurring further south. This major division in reef ecosystems reflected a boundary near Cape Grim and Little Musselroe Bay between two biogeographical provinces. Each of the two bioprovinces was divisible into four biogeographical regions (bioregions), which occurred along the northern Tasmanian coast and at the Kent Group, Furneaux Group and King Island in Bass Strait, and along the northeastern, southeastern, southern and western coasts of Tasmania. In contrast to these patterns identified using data on coastal reef communities, regional classifications for estuarine and soft-sediment faunas (based on the distribution of beach-washed shells and beach-seined fishes) were less clearly defined. In order to manage and protect Tasmanian inshore plants and animals in accordance with the principle of ecologically sustainable development, an integrated system of representative marine protected areas is considered -
