Astroscopus, the electric stargazers, is a genus of stargazers, a type of percomorph fish from the family Uranoscopidae, part of the order Labriformes. [3] The species in this genus are anatomically distinct uranoscopids, being characterized by internal nares and being the only group of marine bony fish having organs which produce electricity which are derived from the extraocular muscles. They are found on the Atlantic and Pacific coasts of the Americas. [4]
There are four extant and one extinct species included in Astroscopus: [5]
Goosefishes, sometimes called anglers or monkfishes, are a family, the Lophiidae, of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. The family includes 30 recognized species. These fishes are found in all the world's oceans except for the Antarctic Ocean.
Astroscopus guttatus or the northern stargazer is a fish belonging to the Uranoscopidie family and was first described by Charles Conrad Abbott in 1860. Members of the Uranoscopidae family are characterized by dorsally or dorsolaterally directed eyes placed on or near the top of a large, flattened cuboid head, an oblique to vertical mouth often lined with cutaneous cirri, and an elongated, sub-compressed body. The Astroscopus genus consists of three species: Astroscopus guttatus, Astroscopus Y-graecum, and Astroscopus zepherus. Typically found on the Atlantic shores between the states of North Carolina and New York in the United States, the Northern Stargazer can sometimes be confused with its sister species the Southern Stargazer, Astroscopus y-graecum. Both A. guttatus and A. Y-graecum overlap in their distributions in Cape Hatterus One way to distinguish the Northern Stargazer from the Southern Stargazer is by the presence of numerous small white spots closely spaced along its head and back, whereas the Southern Stargazer has fewer, larger spots on its back. The Northern Stargazer is a moderately sized fish that can reach lengths of 22 inches (56 cm). The northern stargazer can be found buried in sandy substrate at depths up to 120 feet where the species remains buried awaiting prey. Stargazers have a flat forehead with a lot of body mass up front near the mouth creating a body plane optimal for remaining buried under sandy substrate.
The stargazers are a family, Uranoscopidae, of labriform ray-finned fish that have eyes on top of their heads. The family includes about 51 species in eight genera, all marine and found worldwide in shallow and deep saltwaters.
Rachycentron is the only known member genus of the family Rachycentridae. The genus contains a single living species, the cobia, and the Late Miocene fossil species Rachycentron stremphaencus from Maryland.
The cornetfishes or flutemouths are a small family, the Fistulariidae, of extremely elongated fishes in the order Syngnathiformes. The family consists of a single genus, Fistularia, with four species, found worldwide in tropical and subtropical marine environments.
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 trumpetfishes are three species of highly specialized, tubularly-elongated marine fishes in the genus Aulostomus, of the monogeneric family Aulostomidae. The trumpetfishes are members of the order Syngnathiformes, together with the seahorses and the similarly built, closely related cornetfishes.
Dactyloscopus is a genus of sand stargazers native to the coasts of the Americas.
Uranoscopus is a genus of stargazer fish from the family Uranoscopidae. The name Uranoscopus is from the Greek, ouranos, "sky" and skopein, "to watch".
The Atlantic stargazer is a marine, subtropical fish of family Uranoscopidae. Its body is suited for living on the sea floor, and is one of few fish capable of bioelectrogenesis, or the ability to generate an electric charge.
Astroscopus countermani is an extinct species of stargazer described from a cranium found in Tortonian deposits of the Calvert Cliffs of what is now Maryland. A. countermani is very similar to its living relatives.
Linophryne, the bearded seadevils, is a genus of marine ray-finned fishes belonging to the family Linophrynidae, the leftvents. These deep sea anglerfishes are found in the Atlantic, Indian and Pacific Oceans.
Microcottus is a small genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern Pacific Ocean.
Triglops is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
Lopholatilus is a small genus of tilefishes native to the western Atlantic Ocean.
Pristigenys is a genus of marine ray-finned fish in the family Priacanthidae. It contains five extant species and one extinct species, P. substriata, which is known from fossils found in the Eocene of Monte Bolca, Italy.
The St. Marys Formation is a geologic formation in Maryland and Virginia, United States. It preserves fossils dating back to the Miocene Epoch of the Neogene period. It is the youngest Miocene formation present in the Calvert Cliffs and is part of the Chesapeake Group.
Xenocephalus is a genus of ray-finned fish from the family Uranoscopidae, the stargazers. They are found in the Indo-Pacific region and are benthic, ambush predators.
Kathetostoma is a genus of bony fish from the family Uranoscopidae, the stargazers. They are demersal predators which are found in the western Atlantic, Pacific and Indian Oceans, with most species around Australia and New Zealand.
Uranoscopus brunneus, the dark-finned stargazer, is a member of the group Uranoscopidae, the benthic living fishes distributed worldwide in tropical and temperate oceans.
