Scolichthys greenwayi is a species of freshwater fish of the family Poeciliidae. It is found in flowing waters along the Rio Chixoy and Rio Salinas system in Alta Verapaz, Guatemala. [1]
The species was first described in 1967 by Donn Eric Rosen. It is placed in subfamily Poeciliinae. [1] Its specific epithet refers to James Greenway. [2]
Rosen described Scolichthys greenwayi as having a diffuse and dusky midlateral stripe with a large dark blotch in front of the dorsal fin's origin. Above this stripe, the species has a reticulate pattern, and below it, the side is a brilliant blue with a lead-white lower belly. Dorsal and caudal fins are a bright orange-yellow. [2] It reaches a length of 3.5 cm (1.4 in). [1]
Scolichthys greenwayi is a livebearing fish with a gestation period of 28 days, after which it produces ten to thirty young. [1]
The sailfin molly is a livebearer fish typically found in both freshwater and brackish waterways along the East Coast of the United States, from North Carolina south to Florida, and around the Gulf of Mexico to Texas, and south to the Yucatán Peninsula of Mexico. Given their preference for more brackish water conditions, mollies are often found within just a few yards or miles of the ocean, inhabiting coastal estuaries, lagoons, river deltas and swamps, as well as tidal areas with a regular inflow of oceanic minerals and nutrients mixing with inland freshwater sources.
Hypancistrus is a genus of loricariid catfish originating from the Amazon basin in South America. Unlike many of the other Loricariids, however, some Hypancistrus species are more carnivorous and enjoy meat in their diet. Hypancistrus species are popular aquarium fish, including such popular fish as the zebra pleco and Queen Arabesque pleco.
The tenspine grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found along the western coast of Mexico and Central America, but is a very rare fish of which little information exists.
Greenway's grunter is a species of freshwater ray-finned fish, a grunter from the family Terapontidae. It is endemic to the northern part of Western Australia.
Acanthomorpha is an extraordinarily diverse taxon of teleost fishes with spiny fin rays. The clade contains about one-third of the world's modern species of vertebrates: over 14,000 species.
The Chiapas swordtail or upland swordtail is a species of livebearing freshwater fish of family Poeciliidae, and genus Xiphophorus. It is, therefore, in the same genus as the common platy and the swordtail. The Chiapas swordtail was discovered and first described by Donn E. Rosen in 1960, along with four other species of Xiphophorus.
The rainwater killifish is a small silvery fish with yellow flashes and diamond shaped scales that is widespread from Cape Cod, Massachusetts, through to Tampico, Mexico. It is commonly found in large numbers in fresh to brackish estuarine environments. It feeds on tiny crustaceans, mosquito larvae, small worms, and mollusks. It can reach up to 62 mm.
Genicanthus bellus, the ornate angelfish, bellus angelfish or bellus lyretail angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the Indo-Pacific region.
Bellator militaris, the horned sea robin, is a species of marine ray-finned fish belonging to the family Triglidae, the sea robins. This fish is found in the western Atlantic Ocean.
James Cowan Greenway was an American ornithologist. An eccentric, shy, and often reclusive man, his survey of extinct and vanishing birds provided the base for much subsequent work on bird conservation.
Scolichthys is a genus of poeciliid fishes endemic to river basins in Guatemala.
Deuterodon pelecus is a species of characid fish from Brazil. It can be distinguished from other species by: its body depth ; its short and pointed snout smaller than the orbital diameter; and a reduced number of branched anal fin rays. D. pelecus also differs from members of its genus by its characteristic color pattern. It possesses a single humeral spot that is constricted to the region above the lateral line; at the same time it shows a conspicuous midlateral body stripe from opercle to the caudal fin base, an autapomorphy of this precise species. Other Deuterodon species have a humeral spot that is vertically or horizontally elongate and have the midlateral stripe becoming faint near that humeral spot. The species name is derived from the Greek pelekus, meaning "axe", referring to the pigmentation shape resulting from the adjoinment of the humeral spot with the midlateral stripe.
Hyporthodus mystacinus, the misty grouper, black grouper, convict grouper, eightbar grouper or moustache grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is primarily found in the Caribbean and the Gulf of Mexico with populations present around the Galapagos Islands and Central American coastlines.
Donn Eric Rosen (1929-1986) was a member of the staff of the American Museum of Natural History. He was a Distinguished Fellow of the American Society of Ichthyologists and Herpetologists.
Iguanodectes adujai is a species of freshwater fish that inhabits the rivers of South America. It largely prefers slow-moving blackwater habitats, though it has a slender body that suggests a further affinity for flowing water. It has a distinct lateral stripe in two horizontal sections, with bright-red at the top and yellow at the bottom.
Astyanax angustifrons, sometimes referred to as the Campeche tetra, is a small freshwater fish from the rivers of Central and South America. It has a healthy distribution across southern Mexico and northern Guatemala, and is relatively common within its native range. Details regarding its diet and behavior are sparse, but it lives in areas with plentiful riparian vegetation, and most other members of the genus are omnivorous. Its habitat includes places affected by pollution and human activity; nonetheless, it is not endangered.
Astyanax baileyi is a small freshwater fish native to northern Guatemala. Based on several visual aspects, it was once considered a member of the genus Bramocharax, which is now obsolete, and has since been synonymized with Astyanax. As such, former members of Bramocharax are now a part of Astyanax, like Astyanax bransfordii and Astyanax caballeroi.
Xiphophorus cortezi, the delicate swordtail, is a species of poeciliid fish from Mexico.
Poecilia kykesis, also known as the Usumacinta molly, Petén molly, spiketail molly, or swordtail molly, is a poeciliid fish species native to the fresh and brackish waters of Mexico, Guatemala, and Belize. It belongs to the sailfin molly clade, with males exhibiting an enlarged dorsal fin. The species has a notably controversial naming history, with the former name, Poecilia petenensis, now referring to a short-finned molly species. It is a livebearer sometimes kept in aquaria.
Xiphophorus signum is a poeciliid fish endemic to Guatemala. It occurs in only one creek and adjacent pools, making it a vulnerable species.
