Brachiopsilus is a genus of marine ray-finned fishes belonging to family Brachionichthyidae, the handfishes. The fishes in this genus are endemic to Australia.
Brachiopsilus was first proposed as a genus in 2009 by the Australian zoologists Peter R. Last and Daniel C. Gledhill when they described the three species within the genus. They designated B. ziebelli as the type species in the new genus. [1] [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]
Brachiopsilus is a combination of brachium, which means "arm", and psilos, meaning "bare" or "smooth". This is an allusion to the smooth skin on the body and the arm-like pectoral fin. [4]
Brachiopsilus currently has 3 recognised species within it: [5]
Brachiopsilus handfishes are characterised by having a relatively deep body, the depth of the body at the origin of the second dorsal fin being equivalent to 31% to 43% of the standard length. They have large heads, the length of the head is equivalent to between 43% and 58% of the standard length and is slightly compressed in cross section. They have rather short caudal peduncles. The illicium may be short or long but is thin and is between 3 and 5 times the length of the esca. They have thick skin which is smooth but may have low ridges within it but does not have any enlarged, fleshy warts on it. The body or fins are brightly coloured or may have a strong pattern of speckles. The pectoral fin typically has 9 fin rays, sometimes 10 and 9 or 10 soft rays in the anal fin. [6] Th smallest fish in the genus is the humpback handfish (B. dossenus) with a maximum published standard length of 6.5 cm (2.6 in) while the largest is Ziebell's handfish (B. ziebelli) with a maximum published standard length of 11.7 cm (4.6 in). [5]
Brachiopsilus handfishes are endemic to southern Australia where they are found off the coasts of Victoria (state) and Tasmania. [2]
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.

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.
Glauert's anglerfish is species of marine ray-finned fish belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. This species is the only species in the monospecific genus Allenichthys. This species is endemic to southern Australia.
Tetrabrachiidae, or the four-armed frogfishes or doublefin frogfishes, is a small family of marine ray-finned fishes belonging to the suborder Antennarioidei in the order Lophiiformes, the anglerfishes. These fishes are found in relatively shallow waters of the eastern Indian Ocean and western Pacific Ocean.
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.

The only species in the genus is Phyllophryne scortea, the white-spotted anglerfish, smooth anglerfish or smooth frogfish, which is endemic to southern Australia.
Dibrachichthys is a monospecific genus belonging to the family Tetrabrachiidae, the four-armed frogfishes. The only species in the genus is Dibrachichthys melanurus, the twoarm humpback anglerfish, which is found in the eastern Indian and western Pacific Oceans.
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.
