Ogcocephalus rostellum, the palefin batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. It is found in the western Atlantic Ocean.
Ogcocephalus rostellum was first formally described in 1980 by the American ichthyologist Margaret G. Bradbury with its type locality given as Atlantic coast of Florida at 29°10'N, 80°19'W, Combat station 336, from a depth of 25 fathoms (150 ft; 46 m). [2] The genus Ogcocephalus is classified within the "Eastern Pacific/Western Atlantic clade" of the family Ogcocephalidae. [3] The family Ogcocephalidae is classified in the monotypic suborder Ogcocephaloidei within the order Lophiiformes, the anglerfishes in the 5th edition of Fishes of the World . [4]
Ogcocephalus rostellum is a member of the genus Ogcocephalus, the name of which is a combination of ogkos, which means “hook”, and cephalus, meaning “head”, an allusion to the pointed rostrum on the snout snout of the type species. The specific name rostellum, is the diminutive of rostrum, an allusion to the small snout described for this species. [5]
Ogcocephalus rostellum has a low, flattened head and a triangular disc, with a pointed snout and a rather short rostrum, small and conical in juveniles and shelf-like in larger specimens. The esca has 3 fleshy points and it is retracted into a small illicial cavity beneath the rostrum. The eyes are on the sides of the head and it has a relatively small mouth. There is a blunt, poorly developed, simple spine on the lower, posterior angle of the operculum. The gill rakers are oval shaped plates which are covered in small teeth and the gill openings are small, opening behind the upper base of the pectoral fin, this fin and the pelvic fin's are limb-like with the pectoral fins not widely attached to the body. The dorsal and anal fins are small, the dorsal fin is covered in skin and is on the tail while the anal fin is fleshy and under the tail. he upper surface of the body is covered in large buckler-like scales and with conical spines, the lower surface of the body has a complete covering of pointed, bony scales and the underside of the tail has a dense covering of small spines, apart from a few conical spines on its midline. The upper body is brown, broken by white blotches with dark mottles on the axilla of the pectoral fin. Thin black lines radiate from the midpoints of the buckler-like scales. There is an elongated cluster < of circular dark spots in each shoulder, with a small number of bright orange spots intermingled with them. The caudal fin andpectoral fin both have brow, mottled bases with yellow middles and vermilion edges with a thin black outer margin. The mouth is intensely red and the iris is brassy pink with a ring of tan spots. [6] The palefin batfish has a maximum published total length of 19 cm (7.5 in). [7]
Ogcocephalus rostellum is found in the Western Atlantic Ocean where it is found from North Carolina, south along the southeastern coast of the United States to the Bahamas and into the Gulf of Mexico from the Florida Keys north to the Florida Middle Grounds. [1] The palefin batfish is a demersal fish found at depths between 13 and 378 m (43 and 1,240 ft) on soft subtrates. [6]
The pancake batfish, Atlantic pancake batfish, Louisiana pancake batfish or spiny batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes or seabats. This species is found in the Western Atlantic Ocean.
Ogcocephalus vespertilio, the Brazilian batfish or seadevil, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. This species is found in the Western Atlantic Oceean. The Brazilian batfsish is the type species of the genus Ogcocephalus.
The red-lipped batfish or Galápagos batfish is a fish of unusual morphology found around the Galápagos Islands and off Peru at depths of 3 to 76 m. Red-lipped batfish are closely related to rosy-lipped batfish, which are found near Cocos Island off the Pacific coast of Costa Rica. This fish is mainly known for its bright red lips. Batfish are not good swimmers; they use their highly adapted pectoral, pelvic and anal fins to "walk" on the ocean floor. When the batfish reaches maturity, its dorsal fin becomes a single spine-like projection.
Ogcocephalus parvus, the roughback batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the batifishes. This species has a wide distribution in the Western Atlantic Ocean.
Malthopsis, the gnome batfishes or triangular batfishes, is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The triangular batfishes are distributed throughout the warmer waters of the world, although they are absent from the Eastern Atlantic Ocean. The genus was originally proposed in 1891 by the British naturalist Alfred W. Alcock.
Ogcocephalus is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The species in this genus are found in the Eastern Pacific Ocean and Western Atlantic Ocean, with most species in the eastern Atlantic Ocean where they live at shallower depths than the other ogcocephalid genera.
Zalieutes is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The species in this genus are benthic fishes found in deep waters in the Western Atlantic and Eastern Pacific Oceans.
Ogcocephalus radiatus or the polka-dot batfish is an arrow-shaped fish in the family Ogcocephalidae with an elongated thin tail. It is dorso-ventrally flattened with round pectoral fins that sit flat on the bottom of the sea floor. It uses its pectoral fins and pelvic fins to "walk" along the bottom in a side-to-side shuffling motion.
Ogcocephalus corniger, the longnose batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. This fish is found at depths between 29 and 230 m in the Atlantic Ocean, ranging from North Carolina to the Gulf of Mexico and the Bahamas. Like other members of the family Ogcocephalidae, it has a flat triangular body with coloring varying from yellowish to purple with pale, round spots. The lips are orange-red. Projecting from its head is a characteristic structure that is shared by other anglerfish.
Halieutichthys bispinosus, the two-spine batfish or spiny batfish, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes or seabats. This species is found in the Western Atlantic Ocean.
Ogcocephalus notatus, the marked batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. It is found in the tropical western Atlantic Ocean.
Malthopsis gnoma, the Atlantic triangular batfish, gnome seabat or grotesque seabat, is a species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes. The grotesque seabat is found in the Western Atlantic Ocean, in the Gulf of Mexico and Caribbean.
Ogcocephalus porrectus, the rosy-lipped batfish, is endemic to Cocos Island off the Pacific coast of Costa Rica. Though members of Ogcocephalidae occur in tropical, warm waters in both the Western Atlantic and Eastern Pacific. Rosy-lipped batfish generally reside in shallow to deep water benthic zones with a bathymetric range of 35 – 150 m. The syntypic series was collected at 120 m on a rocky bottom. What makes this fish distinctive are its rosy red lips, specialized pectoral fins used for "walking", and an illicium used for attracting prey.

Ogcocephalus pumilus, the dwarf batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. It is found in the western Atlantic Ocean. It is the smallest species in the genus Ogcocephalus.
Ogcocephalus cubifrons, the spotted batfish or polka-dot batfish, is a species of ray-finned fish belonging to the family Ogcocephalidae, the deep sea batfishes. This is an uncommon demersal fish found in the Western Atlantic Ocean and the southern Gulf of Mexico, in the United States, Mexico and the Bahamas.
