Bathymaster is a genus of marine ray-finned fishes belonging to the family Bathymasteridae, the ronquils. These fishes are found in the northern Pacific Ocean.
Bathymaster was first proposed as a monotypic genus in 1873 by the American paleontologist and biologist Edward Drinker Cope when he described its type species Bathymaster signatus from Sitka, Alaska. [1] [2] The genus is classified in the family Bathymasteridae which is in the Scorpaeniform suborder Zoarcoidei. [3] The genus name, Bathymaster, can be translated from the Greek to mean "deep searcher". [4]
There are currently four recognized species in this genus: [5]
Bathymaster ronquils are distinguished from other genera of ronquils by having naked, i.e. scaleless, cheeks and opercula. there are 5 or 6 pores on the mandibles and the pores on the preoperculum are grouped in an 8:1:1 pattern, There are between 83 and 102 pored scales in the lateral line and these are not greater in size than the nearby scales. The dorsal fin is not continuous and the first dorsal fin has 3 pliable spines. [6] The largest species is B. signatus with a maximum published total length of 38 cm (15 in) while the smallest is B. derjugini which has a maximum published total length of 18 cm (7.1 in). [5]
Bathymaster ronquils are found in the northern North Pacific from Washington north and west to Hokkaido. [7] The searcher has been found as deep as 300 m (980 ft) but these fishes are typically found in shallow coastal waters at depths no greater than 200 m (660 ft). [6] They are cold water benthic fishes. [7]
Ronquils is a small family marine ray-finned fish, the Bathymasteridae. These fishes are found only in Arctic and North Pacific waters. This family contains just seven species in three genera. The larger species are important to commercial fisheries as food fish. Ronquils are most closely related to the eelpouts and prowfish in the suborder Zoarcoidei of the order Scorpaeniformes.
Anarhichadidae, the wolffishes, sea wolves or wolf eels, is a family of marine ray finned fishes belonging to the order Scorpaeniformes. These are predatory, eel shaped fishes which are native to the cold waters of the Arctic, North Pacific and North Atlantic Oceans.
Pholidae is a family of marine ray-finned fishes, known as gunnels, in the scorpaeniform suborder Zoarcoidei. These are fishes of the littoral zone and are mainly found in North Pacific Ocean, with two species found in the North Atlantic Ocean and Arctic Ocean.
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean.
The quillfish,, is a species of marine ray-finned fish, it is the only species in the genus Ptilichthys and family Ptilichthyidae. This fish occurs in the northern North Pacific Ocean.
The stripedfin ronquil, also known as the bluebanded ronquil, is a species of marine ray-finned fish belonging to the family Bathymasteridae, the ronquils. This fish is found in the eastern Pacific Ocean.
Bathymaster signatus, the searcher, is species of marine ray-finned fish belonging to the family Bathymasteridae, the ronquils. This species is found in the northern Pacific Ocean.
Zoarcoidei is a suborder of marine ray-finned fishes belonging to the order Scorpaeniformes. The suborder includes the wolffishes, gunnels and eelpouts. The suborder includes about 400 species. These fishes predominantly found in the boreal seas of the northern hemisphere but they have colonised the southern hemisphere.
Anarhichas is a genus of marine ray-finned fishes belonging to the family Anarhichadidae, the wolffishes or sea wolves. These fishes are found in the northern North Atlantic and North Pacific oceans.
Cryptacanthodes is a genus of is a genus of marine ray-finned fishes belonging to the monogeneric family Cryptacanthodidae, commonly referred to as wrymouths. Three of the four species are found in the Pacific Ocean with one species native to the western Atlantic Ocean where they are benthic fishes, tunneling through soft substrates. It is currently the only known genus in its family.
Ernogrammus is a genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific Ocean.
Rathbunella is a genus of marine ray-finned fishes belonging to the family Bathymasteridae, the ronquils. These fishes are found in the eastern Pacific Ocean.
The northern ronquil is species of marine ray-finned fish belonging to the family Bathymasteridae, the ronquils. This species is found in the eastern Pacific Ocean. This species is the only known member of its genus.
The stippled gunnel is a species of marine ray-finned fish belonging to the family Pholidae, the gunnels. It is the only species in the monospecific genus Rhodymenichthys. It is found in the northern North Pacific Ocean.
Stichaeinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
The fourline snakeblenny is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. It is the only species in the monotypic genus Eumesogrammus. This fish is found in the Western North Atlantic, Arctic and North Pacific Oceans.
The Arctic shanny is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. This species occurs in the North Pacific, Arctic and western North Atlantic Oceans.
Opisthocentrinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific Ocean.
Askoldia is a monotypic genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks and shannies. Its only species is Askoldia variegata which is found in the northwestern Pacific Ocean.
Gymnelinae is a subfamily of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. Most species are found in the North Pacific Ocean but one genus is cosmopolitan, and another is endemic to the Southern Ocean.
