Lawrence Rocks
The Lawrence Rocks are a group of two rocky islets, 6.8 ha and 1.5 ha in area, with an associated reef, 2.4 km south-east of Point Danger in western Victoria, Australia, and about 6 km south-east of the city of Portland. Geologically, the group is formed from the remnants of an extinct volcano, with the islets composed of basalt and tuff. The islets were sighted by Lieutenant James Grant on 5 December 1800 from the survey brig HMS ''Lady Nelson'' and named for Captain Effingham Lawrence, one of the Elder Brethren of Trinity House. Fauna The rocks are protected as a nature reserve and are the site of a breeding colony of Australasian gannets, the overspill from which led to the establishment of a sister colony at Point Danger. The group has been identified by BirdLife International as an Important Bird Area An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being global ...

Bass Strait
Bass Strait () is a strait separating the island state of Tasmania from the Australian mainland (more specifically the coast of Victoria, with the exception of the land border across Boundary Islet). The strait provides the most direct waterway between the Great Australian Bight and the Tasman Sea, and is also the only maritime route into the economically prominent Port Phillip Bay. Formed 8,000 years ago by rising sea levels at the end of the last glacial period, the strait was named after English explorer and physician George Bass (1771-1803) by European colonists. Extent The International Hydrographic Organization defines the limits of Bass Strait as follows: :''On the west.'' The eastern limit of the Great Australian Bight Cape Otway">eing a line from Cape Otway, Australia, to King Island (Tasmania)">King Island and thence to Cape Grim, the northwest extreme of Tasmania]. :''On the east.''

Nature Reserves In Victoria (Australia)
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Islands Of Victoria (Australia)
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The ...

Seabird Colonies
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal Hunting
Seal hunting, or sealing, is the personal or commercial hunting of seals. Seal hunting is currently practiced in ten countries: United States (above the Arctic Circle in Alaska), Canada, Namibia, Denmark (in self-governing Greenland only), Iceland, Norway, Russia, Finland and Sweden. Most of the world's seal hunting takes place in Canada and Greenland. The Canadian Department of Fisheries and Oceans (DFO) regulates the seal hunt in Canada. It sets quotas (total allowable catch – TAC), monitors the hunt, studies the seal population, works with the Canadian Sealers' Association to train sealers on new regulations, and promotes sealing through its website and spokespeople. The DFO set harvest quotas of over 90,000 seals in 2007; 275,000 in 2008; 280,000 in 2009; and 330,000 in 2010. The actual kills in recent years have been less than the quotas: 82,800 in 2007; 217,800 in 2008; 72,400 in 2009; and 67,000 in 2010. In 2007, Norway claimed that 29,000 harp seals were killed, Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Fur Seal
The brown fur seal (''Arctocephalus pusillus''), also known as the Cape fur seal, South African fur seal and Australian fur seal, is a species of fur seal. Description The brown fur seal is the largest and most robust member of the 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 in length on average and weigh . Females are smaller, averaging in length and typically weighing .Kin ...

Hauling-out
Hauling-out is a behaviour associated with pinnipeds ( true seals, sea lions, fur seals and walruses) temporarily leaving the water. Hauling-out typically occurs between periods of foraging activity. Rather than remain in the water, pinnipeds haul-out onto land or sea-ice for reasons such as reproduction and rest. Hauling-out is necessary in seals for mating (with the exception of the Baikal seal) and giving birth (although a distinction is generally made between reproductive aggregations, termed " rookeries", and non-reproductive aggregations, termed "haul-outs"). Other benefits of hauling-out may include predator avoidance, thermoregulation, social activity, parasite reduction and rest. There is much variation in haul-out patterns among different seal species.Hoelzel, A. Rus. (2002). ''Marine Mammal Biology: An Evolutionary Approach''. Blackwell Publishing. . p. 197. Haul-out sites may be segregated by age and sex within the same species. Many species of pinniped have onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Gannet
The Cape gannet (''Morus capensis'') is a large seabird of the gannet family, Sulidae. They are easily identified by their large size, black and white plumage and distinctive yellow crown and hindneck. The pale blue bill is pointed with fine serrations near the tip; perhaps because of the depth and speed of the gannet's dive when fishing (depending on altitude, gannets hit the water at speeds of between ), its beak has no external nostrils into which the water might be forced. Taxonomy German naturalist Hinrich Lichtenstein described the Cape gannet in 1823. The Sulidae, the gannets and boobies, appeared about 30 million years ago. Early Sulidae fossils most resembled the boobies, although they were more aquatic, with the gannets splitting off later, about 16 million years ago. The gannets evolved in the northern hemisphere, later colonising the southern oceans. The most ancient extant species may be the Abbott's booby, possibly the sole survivor of an otherwise extinct sepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooty Oystercatcher
The sooty oystercatcher (''Haematopus fuliginosus'') is a species of oystercatcher. It is a wading bird endemic to Australia and commonly found on its coastline. It prefers rocky coastlines, but will occasionally live in estuaries. All of its feathers are black. It has a red eye, eye ring and bill, and pink legs. Taxonomy John Gould described the sooty oystercatcher in 1845. Its species name is the Latin adjective ''fuliginosus'', "sooty". Two subspecies are recognised, the nominate from the coastline of southern Australia and subspecies ''ophthalmicus'' from northern Australia. The southern subspecies is larger and heavier than the northern. The northern one, with a more yellowish eye ring, is found from the Kimberleys across the top of the country to Mackay in central Queensland. There is considerable overlap, as the southern subspecies has been found up to Cape York. Subspecies ''ophthalmicus'' has been thought distinctive enough to warrant species status and needs further in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is the most common gull of Australia. It has been found throughout the continent, but particularly at or near coastal areas. It is smaller than the Pacific gull (''Larus pacificus''), which also lives in Australia. The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages ( scientific name ''Larus argentatus'', German ''Silbermöwe'', French ''Goéland argenté'', Dutch ''zilvermeeuw''), but is a much larger, robust gull with no overlap in range. Taxonomy It has traditionally been placed in the genus '' Larus'', as is the case with many gulls, but is now placed in the genus '' Chroicocephalus''. Hartlaub's gull (''C. hartlaubii'') of South Africa was formerly sometimes considered to be subspecies of the silver gull. There are three subspecies: * ''C. n. forsteri'' ( Mathews, 1912) – north and northeast Australia, New Caledonia, Loyalty Islands * ''C. n. no ...

Crested Tern
The greater crested tern Retrieved 28 February 2012 (''Thalasseus bergii''), also called crested tern or swift tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to the royal and lesser crested terns, but can be distinguished by its size and bill colour. The greater crested tern has grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter. Its young have a distinctive appearance, with strongly patterned grey, brown and white plumage, and rely on their parents for food for several months after they have fledged. Like all members of the genus ''Thalasseus'', the greater crested tern feeds by plunge diving for fish, usually in marine en ...
