The River Derwent is a river located in Tasmania, Australia. It is also known by the palawa kani name timtumili minanya. The river rises in the state's Central Highlands at Lake St Clair, and descends more than 700 metres (2,300 ft) over a distance of more than 200 kilometres (120 mi), flowing through Hobart, the state's capital city, before emptying into Storm Bay and flowing into the Tasman Sea. The banks of the Derwent were once covered by forests and occupied by Aboriginal Tasmanians. European settlers farmed the area and during the 20th century many dams were built on its tributaries for the generation of hydro-electricity.
The Northern Pacific seastar is an invasive species in Australia.
Frogfishes are any member of the anglerfish family Antennariidae, of the order Lophiiformes. Antennariids are known as anglerfish in Australia, where the term "frogfish" refers to members of the unrelated family Batrachoididae. Frogfishes are found in almost all tropical and subtropical oceans and seas around the world, the primary exception being the Mediterranean Sea.
Handfish are marine ray-finned fishes belonging to the family Brachionichthyidae, a group which comprises five genera and 14 extant species and which is classified within the suborder Antennarioidei in the order Lophiiformes, the anglerfishes. These benthic marine fish are unusual in the way they propel themselves by walking on the sea floor rather than swimming.
Brachionichythys is a genus of marine ray-finned fish belonging to the family Brachionichthyidae, the handfishes. These fishes are confined to the southeastern Indian and southwestern Pacific Oceans off Australia.
The Australian swellshark or draughtboard shark, is a species of catshark, and part of the family Scyliorhinidae, endemic to southern Australia. This bottom-dwelling species can be found on the continental shelf down to a depth of 220 m (720 ft). Usually measuring 1 m long, it is a stout-bodied, broad-headed shark with a short tail and a first dorsal fin much larger than the second. It can be identified by its variegated dorsal coloration of brown or grey patches and numerous spots.
The starry smooth-hound is a houndshark of the family Triakidae. It is found on the continental shelves of the northeast Atlantic, between latitudes 61 and 16° N, from the surface to a depth of 200 m (660 ft).
Asterias amurensis, also known as the Northern Pacific seastar and Japanese common starfish, is a seastar found in shallow seas and estuaries, native to the coasts of northern China, Korea, far eastern Russia, Japan, Alaska, the Aleutian Islands and British Columbia in Canada. Two forms are recognised: the nominate and formarobusta from the Strait of Tartary. It mostly preys on large bivalve molluscs, and it is mostly preyed on by other species of starfish. Population booms in Japan can affect the harvest of mariculture operations and are costly to combat.
Anarhichas minor, the spotted wolffish, spotted sea cat or leopardfish, is a large marine fish of the family Anarhichadidae. This bottom-dwelling species is found across the North Atlantic and adjacent parts of the Arctic Ocean from north of Russia and the Scandinavian Peninsula to the Scotian Shelf, off Nova Scotia, Canada. In Canada the population declined by about 90% from the late 1970s through the early 1990s, particularly in the northern part of its range. In Canada it is classified as a threatened species.
Brachiopsilus is a genus in the handfish family Brachionichthyidae.
Pezichthys is a genus in the handfish family Brachionichthyidae.
Thymichthys is a genus in the handfish family Brachionichthyidae. Like other handfishes, they move by means of walking on their pectoral fins, which resemble hands.
Sympterichthys is a genus in the handfish family Brachionichthyidae with these species:
The deepbody pipefish is a species of pipefish endemic to Australia where it is only found along the southern coast. This species grows to a length of 12.9 centimetres (5.1 in) SL. This species is the only known member of the monotypic genus Kaupus which is named in honour of the ichthyologist Johann Jakob Kaup (1803-1873).
Peter Robert Last is an Australian ichthyologist, curator of the Australian National Fish Collection and a senior principal research scientist at CSIRO Marine and Atmospheric Research (CMAR) in Hobart, Tasmania. He is an elasmobranch expert and has described many new species of shark.
The red handfish is a species of handfish in the genus Thymichthys, found in Frederick Henry Bay, Tasmania.
Ziebell's handfish is a rare Australian handfish in the genus Brachiopsilus. It is known only from eastern and southern Tasmania. Ziebell's handfish may possibly be extinct, as there have been no confirmed sightings since 2007.
The smooth handfish is a possibly extinct species of handfish in the genus Sympterichthys. It was endemic to waters off the coast of Tasmania, mainly the D’Entrecasteaux Channel. It was declared extinct by the IUCN Red List in 2020, marking the first entirely marine fish classified as such. However, in 2021 its status was changed to Data Deficient due to uncertainties over the exhaustiveness of the unsuccessful surveys to find this species.
Moulton's handfish is an endangered species of handfish in the genus Sympterichthys. It is endemic to a few locations off the southeastern coast of Australia. It was first described as a distinct species in 2009 by Peter Last and Daniel Gledhill. It lives at a depth of around 105 metres (344 ft) - 150 metres (490 ft).
The Australian spotted handfish, also known as the Australian handfish or common handfish, is a species of marine ray-finned fish belonging to the family Brachionichthyidae, the handfishes. This species is endemic to eastern and southern Australia.
