Posidonia ostenfeldii is a species of seagrass that occurs in the southern waters of Australia.
A species of Posidonia . A perennial rhizomatous herb that appears as clumps on sand in marine habitat. It is found at depths between 1 and 15 metres. The leaf blades are 6–12 mm wide.
This species is found in waters around the southern coast of Australia. Posidonia ostenfeldii is recorded at the edge of the Esperance Plains, the Archipelago of the Recherche, at the southern coast of Southwest Australia.
This species is contained by the Posidoniaceae family, one of eight occurring in southern Australia. The ninth member, Posidonia oceanica , is found in the mediterranean sea. Several related species within Posidonia are described as the Posidonia ostenfeldii complex.
The southern right whale dolphin is a small and slender species of cetacean, found in cool waters of the Southern Hemisphere. It is one of two species of right whale dolphin. This genus is characterized by the lack of a dorsal fin. The other species, the northern right whale dolphin, is found in deep oceans of the Northern Hemisphere and has a different pigmentation pattern than the southern right whale dolphin.
Caulerpa taxifolia is a species of green seaweed, an alga of the genus Caulerpa, native to tropical waters of the Pacific Ocean, Indian Ocean, and Caribbean Sea. The species name taxifolia arises from the resemblance of its leaf-like fronds to those of the yew (Taxus).
King George Sound is a sound on the south coast of Western Australia. Named King George the Third's Sound in 1791, it was referred to as King George's Sound from 1805. The name "King George Sound" gradually came into use from about 1934, prompted by new Admiralty charts supporting the intention to eliminate the possessive 's' from geographical names.
Avicennia marina, commonly known as grey mangrove or white mangrove, is a species of mangrove tree classified in the plant family Acanthaceae. As with other mangroves, it occurs in the intertidal zones of estuarine areas.
The milk shark is a species of requiem shark, and part of the family Carcharhinidae, whose common name comes from an Indian belief that consumption of its meat promotes lactation. The largest and most widely distributed member of its genus, the milk shark typically measures 1.1 m (3.6 ft) long, and can be found in coastal tropical waters throughout the eastern Atlantic and the Indo-Pacific regions. Occurring from the surface to a depth of 200 m (660 ft), this species is common near beaches and in estuaries, and has been recorded swimming up rivers in Cambodia. Juveniles are known to inhabit tidal pools and seagrass meadows. The milk shark has a slender body with a long, pointed snout and large eyes, and is a nondescript gray above and white below. This shark can be distinguished from similar species in its range by the long furrows at the corners of its mouth, and seven to 15 enlarged pores just above them.
The Archipelago of the Recherche, known locally as the Bay of Isles, is a group of 105 islands, and over 1200 "obstacles to shipping", off the south coast of Western Australia. The islands stretch 230 km (140 mi) from east to west and to 50 km (31 mi) off-shore encompassing an area of approximately 4,000 square kilometres (1,544 sq mi). The western group is near Esperance and the eastern group at Israelite Bay. They are located in coastal waters, part of which is designated the Recherche Archipelago Nature Reserve.
Amphibolis antarctica is a species of flowering plant in the family Cymodoceaceae. It is referred to by the common names wire weed or sea nymph, and is a seagrass found in coastal waters of southern and western Australia.
Western Australia has the longest coastline of any state or territory in Australia, at 10,194 km or 12,889 km. It is a significant portion of the coastline of Australia, which is 35,877 km.
Posidonia australis, also known as fibre-ball weed or ribbon weed, is a species of seagrass that occurs in the southern waters of Australia. It forms large meadows important to environmental conservation. Balls of decomposing detritus from the foliage are found along nearby shore-lines.
Posidonia is a genus of flowering plants. It contains nine species of marine plants ("seagrass"), found in the seas of the Mediterranean and around the south coast of Australia.
Posidonia coriacea is a species of seagrass that occurs in the southern waters of Australia.
The Seagrasses of Western Australia are submerged flowering plants found along the coast, around islands, and in Estuaries of Western Australia. The region contains some of the largest seagrass meadows in the world, and is the most diverse in the number of species. The variety of habitats along its western and southern coasts is often soft sands in shallow subtropical waters, ideal for these plants.
Posidonia robertsoniae is one of the seagrasses of Western Australia, submerged flowering plants that occur in the southern coastal waters.
Cymodocea nodosa is a species of seagrass in the family Cymodoceaceae and is sometimes known as little Neptune grass. As a seagrass, it is restricted to growing underwater and is found in shallow parts of the Mediterranean Sea and certain adjoining areas of the Atlantic Ocean.
The pointed-snout wrasse, also known as the long-snout wrasse, is a species of marine ray-finned fish, a wrasse from the family Labridae which is native to coastal waters of the Mediterranean Sea and the Black Sea. This species can also be found in the aquarium trade and is occasionally taken in artisanal fisheries.
The Posidonia clingfish is a species of clingfish native to the Australia coast. This species grows to a length of 2 centimetres (0.79 in) SL. Pale green to pale blue with fine spots forming dark reticulations on back and sides, larger blue spots often on back, and a pinkish to brown line from snout to gill cover. The posidonia clingfish is endemic to southern Australia where its range extends from Corner Inlet in Victoria west as far as Rottnest Island in Western Australia. It occurs down to a depth of 10 metres (33 ft) where it is found on macroalgae and within seagrass beds, its favoured substrate to adhere to is the leaves of the sea grass Posidonia australis. This species is the only known member of its genus and was described by John C. Briggs in 1993 with a type locality of Fiddler's Bay which is 16 kilometres south of Tamby Bay in South Australia. Briggs gave the species the specific name hutchinsi in honour of the ichthyologist Barry Hutchins of the Western Australia Museum in Perth, Western Australia.
Pugnaso curtirostris, the pug-nosed pipefish, is a species of pipefish endemic to the coastal waters of southern Australia. It is found down to a depth of about 11 metres (36 ft) in beds of seagrasses of the genera Posidonia and Zostera. This species grows to a length of 18.2 centimetres (7.2 in) SL. This species is the only known member of its genus.
Heteroscarus acroptilus, the rainbow cale, is a species of weed whiting endemic to Australia where it is found in marine waters along the southern coast. It inhabits rocky reefs that have plentiful growth of brown algae and also in beds of seagrass, particularly those of the genus Posidonia. It occurs at depths of from 1 to 15 metres. This species grows to a length of 24 centimetres (9.4 in) SL. It can also be found in the aquarium trade. This species is the only known member of its genus.
The tubemouth is a species of ray-finned fish, a weed whiting from the family Odacidae. It is endemic to the southern coatsts of Australia where it is camouflaged to live among beds of seagrass.
Posidonia australis seagrass meadows of the Manning-Hawkesbury ecoregion is an endangered ecological community, listed under the EPBC Act of the Commonwealth of Australia on 7 May 2015
