The Chapultepec splitfin, known locally as mexcalpique, is a critically endangered species of fish in the family Goodeidae. It is endemic to Mexico and was originally restricted to lakes and wetlands in the Valley of Mexico, including Lake Texcoco. Through man-made channels it was able to spread to the upper Pánuco River basin. Most native populations disappeared as they were at or near Mexico City, with the waters either being reclaimed, drained, heavily polluted or infested with introduced species. Today the Chapultepec splitfin is only known to survive in three lakes in the Chapultepec park of Mexico City, Lake Xochimilco, Lake Zumpango, Laguna de Tecocomulco northeast of the City where perhaps introduced, and parts of the Pánuco River basin. Most of these remaining populations are small. This species was originally described as Cyprinus viviparus in 1837 by Miguel Bustamante y Septién with the type locality given as "Mexico". In 1860 Pieter Bleeker raised the genus Girardinichthys with a new species Girardinichthys viviparus as its type species, this subsequently proved to be a taxonomy of Cyprinus viviparus.

Atherinosoma microstoma, commonly known as the small mouth hardyhead, is a species of silverside native to southeastern Australia. It occurs in streams, inland lakes, estuaries and the nearby coastal waters of south-eastern Australia, from Tuggerah Lakes in New South Wales to Lake George in South Australia, as well as in the Bass Strait in Tasmania and Victoria. This species frequently forms schools and they prefer to be among sea grass beds or other aquatic vegetation. This species was described as Atherina microstoma by Albert Günther of the British Museum in 1872 with the type locality given as Tasmania. Francis de LaPorte de Castelnau used the species he had named as Atherinosoma vorax as the type species of the genus he called Atherinosoma but this was a synonym for Günther's Atherina microstoma, which became Atherinosoma microstoma.
The ara, otherwise known as the saw-edged perch or the Dageumbari (다금바리) is a species of marine ray-finned fish from the monospecific genus Niphon in the monogeneric family Niphonidae. It is found in the Western Pacific Ocean from Japan south to the Philippines where it inhabits rock reefs and inshore waters with rocky sea beds. This species can grow up to 1 metre (3.3 ft) in total length. The ara was first formally described in 1828 by Georges Cuvier in the Histoire naturelle des poissons which he co-authored with Achille Valenciennes, the type locality was given as the Sea of Japan.
The school bass is a species of marine ray-finned fish, it is the only member of the monotypic genus Schultzea which is part of the subfamily Serraninae which itself is classified within the family Serranidae, along with the anthias and groupers. It is found in the western central Atlantic Ocean. This species is found in deeper waters near coral reefswhere it forms small groups which feed on plankton. The school bass is a synchronous hermaphrodite. The generic name honours the American ichthyologist Leonard Peter Schultz (1901-1986) who was Curator of Fishes at the United States National Museum who examined the specimens described by Loren P. Woods (1914-1979) as Schultzea campachanus, which was later shown to be a synonym of Hildebrand's Serranus beta.
