Filimanus is a genus of marine ray-finned fishes, threadfins from the family Polynemidae. [2]
The fishes of the genus Filimanus have a body which is oblong to moderately deep and compressed. They have a well developed adipose eyelid and the diameter of the eye is longer than the length of the snout. They have a well developed lip on their lower jaws and the teeth on the dentary bone are restricted to its dorsal surface. There are narrow bands of villiform teeth on their jaws, palatine bone and ectopterygoids. The rear joint of the mouth extends past the level of rear margin of the adipose eyelid. The rear margin of the gill cover is serrated. They have two dorsal fins with the first dorsal fin having 8 spines and the second dorsal fin has a single spine and 11 to 13 soft rays while the anal fin has 3 spines and 10 to 15 soft rays. The base of the anal fin is shorter than the length of the head. The pectoral fin contains 13 to 16 unbranched rays and it is placed below the midline of body. The caudal fin is deeply forked but its lobes do not have filaments. [3]
Filimanus species are found in the Indian and western Pacific Ocean, [2] where they are found in waters of depths of 1 to 80 metres (3.3 to 262.5 ft) in depth over sandy and muddy substrates, often found in estuaries. [3]
The following species are classified as within the genus Filimanus:
Filimanus was described as new genus by George S. Myers in 1936 with its only species being based on a single specimen which he identified as Polynemus melanochir but which was subsequently found to be a misidentification and P. melanochir is a valid species now classified in the genus Polydactylus which meant that Myers specimen remained undescribed. Subsequently Ross M. Feltes described it as Filimanus perplexa and added 5 other species to this new genus. Opinion 1761 of the International Commission on Zoological Nomenclature confirmed F. perplexa as the type species of Myers's genus. [3]
Threadfins are silvery grey perciform fish of the family Polynemidae. Found in tropical to subtropical waters throughout the world, the threadfin family contains eight genera and about 40 species. An unrelated species sometimes known by the name threadfin, Alectis indicus, is properly the Indian threadfish.

The Atlantic threadfin is a species of ray-finned fish a threadfin from the family Polynemidae which is native to subtropical and temperate waters of the western Atlantic Ocean and the Gulf of Mexico.
Cirrhitichthys is a genus of marine ray-finned fish, hawkfishes, from the family Cirrhitidae. They are found on tropical reefs in the Indian and western Pacific oceans. Some species can be found in the aquarium trade.
Scolopsis is a genus of marine ray-finned fishes belonging to the family Nemipteridae, the threadfin breams. These fishes are found in the Indian Ocean and the western Pacific Ocean.
The vermilion snapper, the clubhead snapper, night snapper, Brian's red fish or beeliner is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the western Atlantic Ocean.
The smallmouth scad, is a species of tropical marine fish in the jack family Carangidae. The species is endemic to northern Australia, inhabiting primarily inshore waters. It is similar to other scads in the genus Alepes, and is distinguished by a well-developed posterior adipose eyelid, as well as fin membrane spotting and gill raker counts. It is not a large species, with the maximum length reported to be 29.5 cm. It feeds primarily on a variety of small invertebrates, and is of very minor economic importance.
The herring scad, is a common species of tropical marine fish in the jack family Carangidae. The species inhabits the surface waters of coastal regions throughout the Indo-West Pacific region, feeding on a variety of crustaceans and small fishes. It is the largest fish of the scad genus Alepes, growing to a recorded length of 56 cm. The herring scad is identified among the genus Alepes by its more numerous and smaller scutes and the number of gill rakers on the first arch. It is of minor importance to fisheries throughout its range.
The yellowtail scad, is an abundant species of small inshore marine fish of the jack family, Carangidae. The species is widespread in the Indo-Pacific region from east Africa in the west to Hawaii in the east, extending north to Japan and south to Australia. The yellowtail scad is the only member of the monotypic genus Atule and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. Spawning has been well studied in Hawaii, where fish enter bays to spawn, releasing up to 161,000 eggs each between March and October. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods.
The longfin trevally, also known as the longfin kingfish, longfin cavalla or armed trevally, is a species of inshore marine fish in the jack family, Carangidae. The species is common in tropical to subtropical waters of the Indo-Pacific, ranging from South Africa in the west to Japan in the east, typically inhabiting inshore reefs and bays. The species is easily distinguished by its elongate dorsal and anal fin lobes and filamentous dorsal rays, as well as its scaleless breast. Longfin trevally are pelagic predators, taking a variety of small fish, cephalopods and crustaceans, and reach sexual maturity at around 21 cm. The species has a maximum known length of 57 cm and weight of 3.5 kg. The longfin trevally has a very complex taxonomic history which is closely intertwined with another currently valid species, Carangoides ciliarius, which may yet prove to be synonymous. Longfin trevally are of minor importance to fisheries throughout their range and are considered good table fish, and are occasionally taken by anglers.
