Cuttlebone
Cuttlebone, also known as cuttlefish bone, is a hard, brittle internal structure (an internal shell) found in all members of the family Sepiidae, commonly known as cuttlefish, within the cephalopods. In other cephalopod families it is called a ''gladius''. Cuttlebone is composed primarily of aragonite. It is a chambered, gas-filled shell used for buoyancy control; its siphuncle is highly modified and is on the ventral side of the shell. The microscopic structure of cuttlebone consists of narrow layers connected by numerous upright pillars. Depending on the species, cuttlebones implode at a depth of . Because of this limitation, most species of cuttlefish live on the seafloor in shallow water, usually on the continental shelf. The largest cuttlebone belongs to the Australian giant cuttlefish, which lives between the surface and a maximum depth of 100 metres. Human uses In the past, cuttlebones were ground up to make polishing powder, which was used by goldsmiths. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country.

Cuttlefish
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from , with the largest species, the giant cuttlefish (''Sepia apama''), reaching in mantle length and over in mass. Cuttlefish eat small molluscs, crabs, shrimp, fish, octopus, worms, and other cuttlefish. Their predators include dolphins, sharks, fish, seals, seabirds, and other cuttlefish. The typical life expectancy of a cuttlefish is about 1–2 years. Studies are said to indicate cuttlefish to be among the most intelligent invertebrates.

Sepia Braggi
''Sepia braggi,'' the slender cuttlefish, is a species of cuttlefish native to the Indo-Pacific Ocean. It has been found in coastal waters of southern Australia. This species was first collected in South Australia by its namesake, William Lawrence Bragg. ''Sepia braggi'' was then described by Sir Joseph Cooke Verco in 1907.''Sepia braggi'' is part of the subgenus ''Doratosepion'' which contains to 41 species of cuttlefish in total. Description ''Sepia braggi'' is a relatively small species of cuttlefish. Females of the species are larger than males and they grow to a mantle length of 80 mm and 49 mm, respectively. The mantle elongates to 3 times longer than it is wide. The mantle is cigar-shaped and triangular towards the anterior end. Narrow fins extend along the lateral margin of the mantle and widen along the posterior. The head is short and narrower than the mantle. The cuttlebone tends to have a similar length to the mantle. The common name of ''S. braggi'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepia Apama
Giant cuttlefish also known as the Australian giant cuttlefish (scientific name ''Sepia apama''), is the world's largest cuttlefish species, growing to in mantle length and up to in total length (total length meaning the whole length of the body including outstretched tentacles). They can be over in weight. Using cells known as chromatophores, the cuttlefish can put on spectacular displays, changing color in an instant. The giant cuttlefish is native to temperate and subtropical waters of Australia, from Brisbane in Queensland to Shark Bay in Western Australia and Tasmania to the south. It occurs on rocky reefs, seagrass beds, and sand and mud seafloor to a depth of . In 2009 the species was listed at Near Threatened on the IUCN Red List of Threatened Species due to an observed declining trend at that time. Lifecycle and reproduction Giant cuttlefish live 1–2 years. Breeding takes place with the onset of the southern winter. Males abandon their normal cryptic coloring an ...

Spencer Gulf
The Spencer Gulf is the westernmost and larger of two large inlets (the other being Gulf St Vincent) on the southern coast of Australia, in the state of South Australia, facing the Great Australian Bight. It spans from the Cape Catastrophe and Eyre Peninsula in the west to Cape Spencer and Yorke Peninsula in the east. The largest towns on the gulf are Port Lincoln, Whyalla, Port Pirie, and Port Augusta. Smaller towns on the gulf include Tumby Bay, Port Neill, Arno Bay, Cowell, Port Germein, Port Broughton, Wallaroo, Port Hughes, Port Victoria, Port Rickaby, Point Turton, and Corny Point. History The first recorded exploration of the gulf was that of Matthew Flinders in February 1802. Flinders navigated inland from the present location of Port Augusta to within of the termination of the water body. The gulf was named ''Spencer's Gulph'' by Flinders on 20 March 1802, after George John Spencer, the 2nd Earl Spencer. The Baudin expedition visited the gulf after Flind ...

Mantle (mollusc)
The mantle (also known by the Latin word pallium meaning mantle, robe or cloak, adjective pallial) is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself. In many species of molluscs the epidermis of the mantle secretes calcium carbonate and conchiolin, and creates a shell. In sea slugs there is a progressive loss of the shell and the mantle becomes the dorsal surface of the animal. The words mantle and pallium both originally meant cloak or cape, see mantle (vesture). This anatomical structure in molluscs often resembles a cloak because in many groups the edges of the mantle, usually referred to as the ''mantle margin'', extend far beyond the main part of the body, forming flaps, double-layered structures which have been adapted for many different uses, including for example, the siphon. Mantle cavity The ''mantle cavity'' is a central fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kangaroo Island
Kangaroo Island, also known as Karta Pintingga (literally 'Island of the Dead' in the language of the Kaurna people), is Australia's third-largest island, after Tasmania and Melville Island. It lies in the state of South Australia, southwest of Adelaide. Its closest point to the mainland is Snapper Point in Backstairs Passage, which is from the Fleurieu Peninsula. The native population of Aboriginal Australians that once occupied the island (sometimes referred to as the Kartan people) disappeared from the archaeological record sometime after the land became an island following the rising sea levels associated with the Last Glacial Period around 10,000 years ago. It was subsequently settled intermittently by sealers and whalers in the early 19th century, and from 1836 on a permanent basis during the British colonisation of South Australia. Since then the island's economy has been principally agricultural, with a southern rock lobster fishery and with tourism growing in impo ...
