The dugong is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow, was hunted to extinction in the 18th century.
Shark Bay is a World Heritage Site in the Gascoyne region of Western Australia. The 23,000-square-kilometre (8,900 sq mi) area is located approximately 800 kilometres (500 mi) north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads:
The common seadragon or weedy seadragon is a marine fish related to the seahorses. Adult common seadragons are a reddish colour, with yellow and purple markings; they have small leaf-like appendages that resemble kelp fronds providing camouflage and a number of short spines for protection. Males have narrower bodies and are darker than females. Seadragons have a long dorsal fin along the back and small pectoral fins on either side of the neck, which provide balance. Common seadragons can reach 45 cm (18 in) in length.
Aipysurus eydouxii, commonly known as the beaded sea snake, the marbled seasnake, and the spine-tailed seasnake, is a species of venomous snake in the family Elapidae. A. eydouxii is unusual amongst sea snakes in that it feeds almost exclusively on fish eggs. As part of this unusual diet, this species has lost its fangs, and the venom glands are almost entirely atrophied.
The blind shark is one of two species of carpet sharks in the family Brachaeluridae, along with the bluegrey carpetshark. Found along the coast of eastern Australia, this nocturnal, bottom-dwelling species is common in rocky areas and seagrass beds from the intertidal zone to a depth of 140 m (460 ft). It often roams in tidal pools where it may be trapped by the receding tide, and can survive for an extended period out of water.
The Western barred bandicoot, also known as the Shark Bay bandicoot or the Marl, is a small species of bandicoot; now extinct across most of its former range, the western barred bandicoot only survives on offshore islands and in fenced sanctuaries on the mainland.
Aipysurus laevis is a species of venomous sea snake found in the Indo-Pacific. Its common names include golden sea snake, olive sea snake, and olive-brown sea snake.
The striped stingaree is a common but little-known species of stingray in the family Urolophidae, endemic to shallow, inshore waters off southwestern Australia. Reaching 61 cm (24 in) long, this species is characterized by an oval, grayish to brownish disc with darker mask-like markings around the eyes and paired blotches at the center of the disc that are extended posteriorly into horizontal lines. Its nostrils have enlarged lobes on the outer margins and a skirt-shaped curtain of skin with a deeply fringed trailing margin in between. Its tail terminates in a relatively large leaf-shaped caudal fin, and bears a small dorsal fin just before the stinging spine. The rounded, flexible disc of the striped stingaree enable it to maneuver through the rocks, reefs, and seagrass that comprise its favored habitats. The International Union for Conservation of Nature (IUCN) has listed this species under Least Concern; it is seldom caught by fisheries due to its habitat preferences.
The spotted stingaree is an uncommon species of stingray in the family Urolophidae, endemic to shallow waters along the coast of southern Australia. It favors rocky reefs and seagrass beds. This species can be readily identified by its nearly circular, dark-colored pectoral fin disc, adorned with a complex pattern of white or cream spots. Its eastern and western forms differ slightly in coloration and have been regarded as separate species. There is a skirt-shaped curtain of skin between its nostrils. Its tail is fairly thick and terminates in a short leaf-shaped caudal fin; a relatively large dorsal fin is present just in front of the stinging spine.
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.
The spiny seahorse, also referred to as the thorny seahorse, is a small marine fish in the family Syngnathidae, native to the Indo-Pacific area. It is classified as a Vulnerable species by the IUCN.
Aipysurus duboisii, also known commonly as Dubois' sea snake and the reef shallows sea snake, is a species of extremely venomous snake in the subfamily Hydrophiinae of the family Elapidae. Its geographic range includes Papua New Guinea, New Caledonia and the northern, eastern and western coastal areas of Australia, that is the Coral Sea, Arafura Sea, Timor Sea and Indian Ocean. It lives at depths up to 80 meters in coral reef flats, sandy and silty sediments which contain seaweed, invertebrates and corals or sponges that can serve as shelter. It preys upon moray eels and various fish that live on the seafloor, up to 110 cm in size. A. duboisii is viviparous, giving birth to live young rather than laying eggs. It displays medium aggressiveness, i.e., will bite if provoked, but not spontaneously. The fangs are 1.8 mm long, which are relatively short for a snake, and the venom yield is 0.43 mg. Aipysurus duboisii is a crepuscular species, meaning that it is most active at dawn and dusk.
The western grasswren, also referred to as the thick-billed grasswren and, formerly, as the textile wren, is a species of bird in the family Maluridae. It is endemic to Australia. It was formerly lumped as the nominate subspecies of the thick-billed grasswren.
Aipysurus apraefrontalis, commonly known as the short-nosed sea snake or Sahul reef snake, is a critically endangered species of venomous sea snake in the family Elapidae, which occurs on reefs off the northern coast of Western Australia. English herpetologist Malcolm Arthur Smith described the species in 1926 from a specimen collected on the Ashmore Reef.
Aipysurus fuscus, commonly known as the dusky sea snake or Timor Reef snake, is a species of sea snake in the family Elapidae. It is found in the Timor Sea between Australia, Indonesia and East Timor and has been classified as endangered.
The Ashmore Reef Marine Park is an Australian marine park that covers the Ashmore Reef, which is located about 630 km (390 mi) north of Broome and 110 km (68 mi) south of the Indonesian island of Rote. The marine park covers an area of 583 km2 (225 sq mi) and is assigned IUCN category Ia. It is one of 13 parks managed under the North-west Marine Parks Network.
The slender-necked sea snake, also known commonly as Cogger's sea snake, is a species of marine venomous snake in the subfamily Hydrophiinae of the family Elapidae. The species is native to waters around western Australia and the southern Pacific Ocean.
Aipysurus mosaicus is a species of snake found in coastal seas of Australia. It is commonly known as the mosaic sea snake.
The brownspotted wrasse, also known as the blue-spotted parrotfish, brown-spotted parrotfish and orangespotted wrasse, is a species of marine ray-finned fish from the family Labridae, the wrasses. It is found in the Indian Ocean off the western and southern coasts of Australia.
