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.
Rathbunella was first proposed as a monotypic genus by the American ichthyologists David Starr Jordan and Barton Warren Evermann in 1896 with Bathymaster hypoplectus, which had been described by Charles Henry Gilbert from Southern California in 1890, as its type species. [1] [2] The genus is classified in the family Bathymasteridae which is in the Scorpaeniform suborder Zoarcoidei. [3] The genus name,Rathbunella honors Richard Rathbun, who was the chief of the Division of Scientific Inquiry in the United States Fish Commission, in recognition of his services to science. [4]
There are currently two recognized species in this genus: [5]
Rathbunella ronquils are distinguished from other genera in the family Bathymasteridae by having the branchiostegal membranes being broadly united , free from isthmus, creating a thick fold. Their gill rakers are short and robust, with small patches of teeth. There are around 100 vomerine teeth which are arranged in concentric arcs which number between 7 and 9. They have between 72 and 88 pored scales in the lateral line. Unlike Bathymaster but like Ronquilus there are scales on the cheeks and crown. [6] The only species for which a maximum published length is given is R. hypoplecta with a total length of 16 cm (6.3 in). [5]
Rathbunella ronquils are found in the eastern North Pacific Ocean where they are distributed from San Francisco Bay in northern California south to Bahia San Carlos in Baja California. [7] They are solitary, demersal fishes of shallow coastal waters in rocky areas. [8] The demersal eggs are guarded by the males. [6]
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.
Insidiator is a genus of marine, demersal ray-finned fish belonging to the family Platycephalidae. These fishes are native to the eastern Indian Ocean and western Pacific Ocean.
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.
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.
The kelp 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 Ulvicola. It is found in the eastern North Pacific Ocean.
Stichaeopsis is a genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the western North Pacific Ocean.
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 Occean.
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.
The bearded eelpout is a species of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. This species is the only species in the monospecific genus Lyconema. It is found in the eastern Pacific Ocean.
