Lates is a genus of freshwater and euryhaline lates perches belonging to the family Latidae. The generic name is also used as a common name, lates, for many of the species.

The moonfish of the genus Mene, the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their lateral compression and thread-like pelvic fins. Today, the genus is represented only by Mene maculata of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as bilong-bilong, chabita, hiwas or tahas.

Ceratodus (from and ) is an extinct genus of freshwater lungfish that was found worldwide during the Mesozoic Era. It has been described as a "catch all", and a "form genus" used to refer to the remains (typically toothplates) of a variety of lungfish belonging to the extinct family Ceratodontidae. Fossil evidence dates back to the Early Triassic. A wide range of fossil species from different time periods have been found around the world in places such as the United States, Argentina, Greenland, England, Germany, Egypt, Madagascar, China, and Australia. Ceratodus is believed to have become ext

Diplomystus is an extinct genus of freshwater and marine clupeomorph fish distantly related to modern-day extant herrings, anchovies, and sardines. It is known from the United States, Canada, China, Uzbekistan and Lebanon from the Late Cretaceous to the middle Eocene. Many other clupeomorph species from around the world were also formerly placed in the genus, due to it being a former wastebasket taxon. It was among the last surviving members of the formerly-diverse order Ellimmichthyiformes, with only its close relative Guiclupea living for longer.

Heliobatis is an extinct genus of stingray in the Myliobatiformes family Dasyatidae. At present the genus contains the single species Heliobatis radians.

Pycnodus (from , 'dense' and 'tooth') is an extinct genus of ray-finned fish from the Eocene period. It is a wastebasket taxon, although many fossils from the Jurassic or Cretaceous are assigned to this genus, only the Eocene species, P. apodus is valid. As its name suggests, it is the type genus of Pycnodontiformes. thumb|left|Proscinetes bernardi, one example of pycnodont that was once assigned as Pycnodus The known whole fossils of Pycnodus are up to long, and have a superficial resemblance to angelfish or butterflyfish. The animals, as typical of all other pycnodontids, had many knob-like

Urosphen is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene.

Sparnodus is an extinct genus of prehistoric perciform fish in the family Sparidae. Species of this genus were nektonic carnivores. These fishes lived in the Cenozoic Era, in the Oligocene and Paleocene (55.8 to 23.03 Ma).

Palaeobalistum is an extinct genus of prehistoric ray-finned fish which ranged from the Cretaceous to Eocene periods.

Palaeoperca is an extinct genus of prehistoric bony fish that lived from the early to middle Eocene. Fossils were found in the Messel pit.
