Trigonopoma gracile is a species of cyprinid fish found in Indonesia and Malaysia.
Differs from all of its congeners by the following combination of characters: lateral line incomplete to absent, perforating 0-6 scales; 29-32 scales along normal course of lateral line; a conspicuous black (bluish black in life) lateral stripe from tip of snout to extremity of median caudal rays; body slender, its depth 4.4-4.8 times in SL (4.0-5.1); caudal peduncle slender than all other Rasbora, its depth 2.3-2.8 times in its length (2.3-3.3); and long and pointed dorsal and anal fins.

The sand goby, also known as a polewig or pollybait, is a species of ray-finned fish native to marine and brackish European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres. This species can reach a length of 11 centimetres (4.3 in) TL. This species is sometimes kept in public aquariums. The sand goby is of a sandy colour, with darker markings on the sides and a creamy-white underside. In the breeding season the male fish has blue spot at the rear of the first dorsal fin, ringed with white. The fish has a slender body, and the head is about a quarter of the total length.
The greenback flounder is a righteye flounder of the genus Rhombosolea, found around southern Australia and New Zealand.
Blicca bjoerkna, alternatively called the white bream or the silver bream, is a European species of freshwater fish in the family Cyprinidae.
Denticetopsis is a genus of catfishes of the family Cetopsidae.
Epinephelus andersoni, the catface grouper, brown-spotted grouper, catface rockcod or brown spotted rockcod, 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 in the southwestern Indian Ocean where it is associated with reefs.
Tristichopterus, with a maximum length of sixty centimetres, is the smallest genus in the family of prehistoric lobe-finned fish, Tristichopteridae that was believed to have originated in the north and dispersed throughout the course of the Upper Devonian into Gondwana. Tristichopterus currently has only one named species, first described by Egerton in 1861. The Tristichopterus node is thought to have originated during the Givetian part of the Devonian. Tristichopterus was thought by Egerton to be unique for its time period as a fish with ossified vertebral centers, breaking the persistent notochord rule of most Devonian fish but this was later reinspected and shown to be only partial ossification by Dr. R. H. Traquair. Tristichopterus alatus closely resembles Eusthenopteron and this sparked some debate after its discovery as to whether it was a separate taxon.
The brownsnout spookfish or brown-snout spookfish is a species of barreleye in the family Opisthoproctidae. It and the glasshead barreleye fish are the only vertebrates known to employ a mirror, in addition to a lens, to focus an image in its eyes. This species probably has a worldwide tropical and temperate distribution; in the Atlantic Ocean it is known from Bermuda, the Bahamas, the Greater Antilles, and the Gulf of Mexico, and in the Pacific Ocean it is known from the California Current region and the South China Sea. It is found in the mesopelagic and bathypelagic zones at a depth of 500–2,400 meters (1,600–7,900 ft), but usually occurs below 1,000 meters. In the Gulf of Mexico it is found shallower, at 310–460 meters (1,020–1,510 ft).
The snake mackerel is the sole species of fish in the monotypic genus Gempylus, belonging to the family Gempylidae. It is found worldwide in tropical and subtropical oceans between the latitudes of 42°N and 40°S; adults are known to stray into temperate waters. It is found to a depth of 600 meters. Populations of the snake mackerel from the Atlantic and the Indo-Pacific differ in vertebral count and number of first dorsal fin spines, and so may represent separate species.
Acanthurus nigricauda, the epaulette surgeonfish, black-barred surgeonfish, eye-line surgeonfish, shoulderbar surgeonfish, white-tail surgeonfish or blackstreak surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. It is native to the Indo-Pacific region.
Garra geba is a species of cyprinid fish in the genus Garra. It is endemic to Ethiopia.
The redlip shiner is a North American species of freshwater cyprinid fish. This shiner can be found in a few streams located in North Carolina, South Carolina, and Virginia. It inhabits rocky pools of clear headwaters, creeks and small rivers. Adults range in length from 40 to 55 mm.
Cancelloxus burrelli, the Slender platanna-klipfish, is a species of clinid found in subtropical waters of the Atlantic Ocean along the South African coast from the Orange River to Algoa Bay in South Africa. It can be found from the intertidal zone down to about 20 metres (66 ft). This species can reach a maximum length of 12 centimetres (4.7 in) TL.
Cancelloxus elongatus, the whiteblotched klipfish, is a species of clinid found in subtropical waters of the Atlantic Ocean along the South African coast. It prefers sandy habitats with nearby rocks at depths of from 10 to 25 metres. It can reach a maximum length of 5 centimetres (2.0 in) TL. This species preys primarily on zoobenthos.
Cancelloxus longior is a species of clinid found in subtropical waters of the South African coast. It can be found in areas with a sand substrate from the intertidal zone to a depth of about 10 metres (33 ft). Males of this species can reach a maximum length of 9.1 centimetres (3.6 in) SL, while females can reach a maximum length of 12.1 centimetres (4.8 in) SL.
Clinus venustris, the speckled klipfish, is a species of clinid that occurs in subtropical waters of the Atlantic Ocean from Namibia to South Africa where it is found in the subtidal zone as well as being a denizen of tide pools. This species can reach a maximum length of 12 centimetres (4.7 in) TL. and feeds primarily on amphipods, isopods, mysids, and echinoderms.
The slender fusilier is a species of marine ray-finned fish, a fusilier belonging to the family Caesionidae. It is native to tropical reefs in the Indian Ocean and the western Pacific Ocean, It is of minor importance to local commercial fisheries. This species is the only known member of its genus.
Astyanax microschemos is a species of characid fish from Brazil. It belongs to the A. scabripinnis species complex and differs from other species outside it by having a lower number of branched anal fin rays and its shallow body depth being about 26.9-29.7 vs more than 35% of its standard length (SL). Compared to species of its own complex, it can be distinguished by the combination of its shallow body depth, and smaller interorbital width. The species name comes from the Greek mikroschemos, meaning "low stature", which refers to the shallow body depth of the animal.
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.
Puntius khohi is a species of fish in the family Cyprinidae in Puntius genus. The species has been discovered in 2004, named and described by Dobriyal, R. Singh, Uniyal, H. K. Joshi, Phurailatpam & Bisht, Gharwhal university in Uttaranchal, India in 2004. The study and paper on Puntius Khohi was published in the Journal of the Inland Fish Socitety the same year (2004). It was collected from a stream Sil Gad which originates from the western slopes of Kalondanda southeast of Lansdowne in the foothills of the Himalayas. The specific name 'kohi refers to the river in which the Sil Gad stream joins.
