The sailfin shiner (Pteronotropis hypselopterus) is a species of cyprinid fish endemic to the southeastern United States. [2]
The sailfin shiner has a deep and compressed body, with a narrow base for the caudal fin. Its lateral line is curved downward. It has a maximum total length of 7 cm (2.75 in). [3]
The fish is pink-brown or olive on the top half and a white or light pink on the bottom half. It has a dark brown stripe that extends from the head to the dorsal fin, and has a steel-blue stripe along the side that has a thin pink to red line bordering above. [3]
The base of the caudal fin has a small red spot on the top and bottom of the side, while a black spot is on the center of the side of the base of the caudal fin. The dorsal fin has a dusky central band, and other fins are a yellow to light orange. The dorsal and anal fins are almost triangular, resembling sails, from which their common name is derived. [4] Breeding males have light orange edges on their dorsal fins. [3]
The fish can be found in Gulf Coast drainages from Alabama to Florida, including in the Mobile Basin. [4]
The fish inhabit sand-bottomed and clay-bottomed pools or run waters of creeks and small rivers. They can often be found around debris or vegetation. [3]
As the fish begins its life as an embryo, its cement glands begin to develop. As a non feeding larva, glue is secreted from the cement glands and the posterior swim bladder forms. The gills, mouth, and gut lining form. The yolk sac becomes streamlined. When swim-up begins, glue secretion stops. The posterior swim bladder becomes inflated. During this stage, the fish is suspended in the water column, and the yolk is almost depleted. The anterior swim bladder forms. After initial feeding, median and pelvic fins develop, and the anterior swim bladder inflates. [5]
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming. Also, the dorsal position of the swim bladder means the center of mass is below the center of volume, allowing it to act as a stabilizing agent. Additionally, the swim bladder functions as a resonating chamber, to produce or receive sound.
The sailfin molly is a species of fish of the genus Poecilia. They inhabit fresh, brackish, salt, and coastal waters from North Carolina to Texas and the Yucatán Peninsula of Mexico.
The West African catshark is a catshark of the family Scyliorhinidae. It is found in the eastern Atlantic between latitudes 20° N and 17° S, at depths between 45 and 500 m. It can grow up to a length of 80 centimetres (31 in). At one time, the West African catshark was considered to be a subspecies of the nursehound, Scyliorhinus stellaris, but is now considered to be a separate species. The reproduction of this catshark is oviparous.
Squalus nasutus, the western longnose spurdog, is a dogfish of the family Squalidae, found on the continental shelf off the northwest and southwest coasts of Western Australia, at depths between 300 and 510 m. Its length is at least 55 cm.
The slender whiting is a poorly known species of inshore marine fish of the smelt whiting family, Sillaginidae that has a distribution limited to the Persian Gulf only. The Slender whiting, like most sillaginids requires careful study to determine its identity, with ray and vertebrae counts as well as swim bladder morphology distinguishing features. This inshore species of fish is commonly taken by fishermen using beach seines and is sold fresh in local markets.
Boutan's whiting, Sillago boutani, is a poorly understood species of coastal marine fish of the smelt-whiting family Sillaginidae that inhabits the waters of the Gulf of Tonkin and south eastern China. Like most sillaginids, the species inhabits areas populated with a number of other whiting species of similar appearance, causing the species to often be misidentified as the well known Sillago sihama, and for this reason its biology is poorly known. The species is taken by seine net in Vietnam and is often exported to Japan.
The striped stingaree is a common but little-known species of stingray in the family Urolophidae, endemic to shallow, inshore waters off southwestern Australia. Reaching 61 cm (24 in) long, this species is characterized by an oval, grayish to brownish disc with darker mask-like markings around the eyes and paired blotches at the center of the disc that are extended posteriorly into horizontal lines. Its nostrils have enlarged lobes on the outer margins and a skirt-shaped curtain of skin with a deeply fringed trailing margin in between. Its tail terminates in a relatively large leaf-shaped caudal fin, and bears a small dorsal fin just before the stinging spine. The rounded, flexible disc of the striped stingaree enable it to maneuver through the rocks, reefs, and seagrass that comprise its favored habitats. The International Union for Conservation of Nature (IUCN) has listed this species under Least Concern; it is seldom caught by fisheries due to its habitat preferences.
The sailfin tang is a marine reef tang in the fish family Acanthuridae. They may live at water depths of 1 - 60 m or more. The fish grow to a maximum length of 40 cm. It has an extensive range throughout Oceania, the Indian Ocean, and the South Pacific. Zebrasoma velifer is a popular fish in the aquarium trade. They are herbivorous fish specializing in filamentous algae. Though their skin is light beige with stripes, it can turn dark brown under stress.
Pseudanthias rubrizonatus, the red-belted anthias, liliac-tip basslet, deepsea fairy basslet, lilac-tipped seaperch, redband anthias, red-band basslet or redbar anthias is a species of marine ray-finned fish, an anthias from the subfamily Anthiinae part of the family Serranidae, the groupers and sea basses. It is found in the Indo-Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 12 cm in length.
Cephalopholis fulva, the coney or the butterfish, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is found in the western Atlantic. It is associated with reefs and is a quarry species for commercial and recreational fisheries. It can be found in the aquarium trade.
The sailfin snapper, blue-lined sea bream or blue-lined sea perch is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the Indo-Pacific region. It is of minor importance to local commercial fisheries and can be found in the aquarium trade. It is currently the only known member of its genus.
The longnose shiner is a species of ray-finned fish in the genus Notropis.
The flagfin shiner is a species of ray-finned fish in the family Cyprinidae (minnows), in the order Cypriniformes (carp).
Pteronotropis is a genus of cyprinid fish endemic to the United States.
Spinachia is a monospecific genus of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. The only species in the genus is Spinachia spinachia, the sea stickleback, fifteen-spined stickleback or fifteenspine stickleback, a species which lives in benthopelagic and in brackish environments of the northeastern Atlantic Ocean. This species, the largest of the sticklebacks, grows to a length of 22 centimetres (8.7 in) SL. This species is the only known member of its genus Spinachia. It is of no interest as a commercial fish.
The striped cusk-eel is a species of fish in the family Ophidiidae. It is found in the northwest Atlantic.
Pelvicachromis sacrimontis is a freshwater fish of the cichlid family known only from a small area of southeastern Nigeria. Currently Fishbase considers this binomial to be a junior synonym of P. pulcher and, it was also known as Pelvicachromis camerunensis, P. pulcher "form B" or P. sp. aff. pulcher but some authorities now consider it to be a valid species. It is occasionally available in the tropical fish trade as "giant krib" and there are three colour morphs – red, green and yellow. And are the most colorful of the Pelvicachromis family. Today its popularity increases due to more order demands by aquarium hobbyists.
The Apalachee shiner is a species of cyprinid fish endemic to the southeastern United States. It is found in the Apalachicola River drainage in Georgia, Alabama, and Florida.
