Sympterichthys is a genus of marine ray-finned fish belonging to the family Brachionichthyidae, the handfishes. These fishes are endemic to Australia.
Sympterichthys was first proposed as a genus in 1878 by the American biologist Theodore Gill with Lophius laevis, a species described in 1804 by the French naturalist Bernard Germain de Lacépède, as its type species. [1] Lophius naevis was preoccuppied by Pierre André Latreille in 1804, so the first available name for this taxon was Chironectes uripennis used by Georges Cuvier in 1817. [2] This genus is classified within the family Brachionichthyidae which the 5th edition of Fishes of the World classifies the family Brachionichthyidae within the suborder Antennarioidei within the order Lophiiformes, the anglerfishes. [3]
Sympterichthys is a combination of symphysis, meaning "grown together", with ichthys, meaning "fish". This is a reference to the first dorsal fin spine being connected to the second by a membrane and to the third spine being connected to the second, soft-rayed dorsal fin, by an incised membrane. [4]
Sympterichthys has the following two species classified within it: [5]
Sympterichthys handfishes are characterised within the handfish family by having their skin covered in small embedded scales with flat, single pointed or two pointed small spines that grow out from the rear margin of the scale bases. They do not have any warts or dermal appendages on their skin. [7] Another characteristic is the fleshy Illicium (fish anatomy) is thick with small spines at its base and has a length which is 2.1 to 3 times that of the head, with the esca being large, sometimes greater than half the length of the illicium, although it has a similar thickness. [8] These fishes have maximum published standard length of 4.4 cm (1.7 in) and 4.5 cm (1.8 in). [5]
Sympterichthys habdfishes are, like all the handfishes, endemic to Australia. The type species, S. unipennis, is known only from its holotype which was collected from the Australian Sea ("Mer de l'Australie"), thought to be Tasmania. [9] S. moultoni is found off southeastern Australia, as far north as off Cape Howe in New South Wales and south to the Bass Strait off northern Tasmania. [8]
Goosefishes, sometimes called anglers or monkfishes, are a family, the Lophiidae, of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. These fishes are found in all the world's oceans except for the Antarctic Ocean.
Lophius piscatorius, commonly known as the angler, European angler or common monkfish, is a monkfish in the family Lophiidae. It is found in coastal waters of the northeast Atlantic, from the Barents Sea to the Strait of Gibraltar, the Mediterranean and the Black Sea. Within some of its range, including the Irish Sea, this species comprises a significant commercial fishery.
Members of the genus Lophius, also sometimes called monkfish, fishing-frogs, frog-fish, and sea-devils, are various species of lophiid anglerfishes found in the Atlantic and Indian Oceans. Lophius is known as the "monk" or "monkfish" to the North Sea and North Atlantic fishermen, a name which also belongs to Squatina squatina, the angelshark, a type of shark. The North European species is Lophius piscatorius, and the Mediterranean species is Lophius budegassa.
The spotted handfish is a rare Australian fish in the handfish family, Brachionichthyidae, classified as critically endangered on the IUCN Red List 2020. It has a highly restricted range, being found only in the estuary of Derwent River, Tasmania, and nearby areas, with the main threat to its existence being an invasive species, the Northern Pacific seastar.
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.
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.
Lophiodes is a genus of marine ray-finned fishes belonging to the family Lophiidae, the goosefishes, monkfishes and anglers. It is one of four extant genera in the family Lophiidae. The fish in this genus are found in the Atlantic, Indian and Pacific Oceans.
Lophiomus is a monospecific genus of marine ray-finned fish belonging to the family, Lophiidae, the goose fishes, monkfishes or anglers. The only species in the genus is Lophiomus setigerus, the blackmouth angler, blackmouth goosefish, broadheaded angler or broadhead goosefish. This fish is found in the Indo-Pacific.
Sladenia is a genus of marine ray-finned fishes belonging to the family Lophiidae, which includes the goosefishes, monkfishes and anglers. These are deepwater anglers found in theIndian Ocean, the Caribbean Sea and the Western Pacific Ocean.
Lophiodes beroe, the white goosefish or white anglerfish, is a species of marine ray-finned fish belonging to the family Lophiidae, the goosefishes, monkfishes or anglers. This species is found in deep waters in the western Atlantic Ocean.
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 know 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.
Lophius vomerinus, the devil anglerfish, Cape monk or Cape monkfish, is a species of marine ray-finned fish belonging to the family Lophiidae, the goosefishes, monkfishes or anglerfishes. This species is endemic to the waters of the southeastern Atlantic and southwestern Indian Oceans around Southern Africa.
Lophiodes mutilus, the smooth angler or smooth monkfish, is a species of marine ray-finned fish belonging to the family Lophiidae, the goosefishes, monkfishes and anglers. This species is found in the Indo-Pacific.
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.
