The River Derwent, also known as timtumili minanya in palawa kani, is a significant river and tidal estuary in Tasmania, Australia. It begins its journey as a freshwater river in the Central Highlands at Lake St Clair, descending over 700 metres (2,300 ft) across a distance of more than 200 kilometres (120 mi). At the settlement of New Norfolk in the Derwent Valley its waters become brackish, flowing through Hobart, the capital city of Tasmania, its seawater estuary eventually empties into Storm Bay and the Tasman Sea.
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 Ocean and southwestern Pacific Ocean off Australia.
The sargassum fish, anglerfish, or frog fish is a species of marine ray-finned fish belonging to the family Antennariidae, the frogfishes, the only species in the genus Histrio. It lives among Sargassum seaweed which floats in subtropical oceans. The scientific name comes from the Latin histrio meaning a stage player or actor and refers to the fish's feeding behaviour.
The starry handfish, starry seabat or minipizza batfish, is species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes or seabats. This fish is found on the continental shelves of the Indo-Pacific oceans at depths of between 50 and 400 m. They are up to 30 cm long.
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.
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.
Galaxias fontanus, the Swan galaxias, is a species of fish in the family Galaxiidae. It is endemic to eastern Tasmania, Australia.
Brachiopsilus is a genus of marine ray-finned fishes belonging to family Brachionichthyidae, the handfishes. The fishes in this genus are endemic to Australia.
Pezichthys is a genus of marine ray-finned fishes belonging to family Brachionichthyidae, the handfishes. The fishes in this genus are endemic to southern Australia. These fishes are all extremely localised in distribution and are rare.
Thymichthys is a genus of marine ray-finned fishes belonging to the family Brachionichthyidae, the handfishes. Like all members of the handfish family these fishes are endemic to Australia.
Sympterichthys is a genus of marine ray-finned fish belonging to the family Brachionichthyidae, the handfishes. These fishes are endemic to Australia.
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 marine ray-finned fishes belonging to the family Brachionichthyidae, the handfishes. Like all members of the handfish family this fish is endemic to Australia. The IUCN classify the red handfish as Critically Endangered.
Ziebell's handfish is a species of marine ray-finned fish belonging to the family Brachionichthyidae, the handfishes. This species is endemic to eastern and southern Tasmania. It is a very rare species and the International Union for Conservation of Nature classifies it as Critically Endangered.
The smooth handfish is a possibly extinct species of handfish in the genus Sympterichthys. It was likely 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. It is known only from its holotype collected by French explorers in 1802.
Moulton's handfish is species of marine ray-finned fish belonging to th efamily Brachionichthyidae, the handfishes. This species is endangered and is endemic to the waters off southeastern Australia.
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.
