Ovalentaria
Ovalentaria is a clade of ray-finned fishes within the Percomorpha, referred to as a subseries. It is made up of a group of fish families which are referred to in ''Fishes of the World's'' fifth edition as'' incertae sedis'', as well as the orders Mugiliformes, Cichliformes, and Blenniiformes. It was named by W. L. Smith and T. J. Near in Wainwright ''et al.'' (2012) based on a molecular phylogeny, but the authors suggested that the group was united by the presence of demersal eggs that are attached to a substrate. Some authors have used the ordinal name Stiassnyiformes for a clade including Mugiloidei, Plesiopidae, Blenniiformes, Atherinomorpha, and Cichlidae, and this grouping does appear to be monophyletic. Classification Based on the Catalog of Fishes (2025), with additional clade names added when necessary: * Subseries Ovalentaria ** Infraseries Atherinomorpha *** Order Atheriniformes **** Suborder Atherinopsoidei ***** Family Atherinopsidae (New World silversides) ...

Blenniiformes
Blenniiformes is an order of percomorph fish in the clade Ovalentaria, of which it is the most diverse group. This order contains several well-known fish groups such as blennies and damselfish. The term is derived from the Latin word '' blennius'', which itself comes from the Ancient Greek word βλεννός (''blennos''), meaning "mucus" or "slime." This refers to the slimy coating that is often found on the scales of blenny fish. The earliest known member of this order is the stem group-damselfish '' Chaychanus'' from the Early Paleocene of Mexico. Taxonomy As with many other percomorphs, most members of this group were originally placed in the Perciformes. Previously, ''Fishes of the World'' defined this order as restricted to the blennies and their close relatives, and placed several taxa such as the damselfishes, jawfishes, and surfperches as indeterminate members of Ovalentaria. Phylogenetic evidence suggests that these families form a successive grade leading to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mugiliformes
Mugiliformes is a small order of percomorph fish in the clade Ovalentaria. This order is recognized by the Catalog of Fishes (2025). It contains only two families: * Mugilidae Jarocki, 1822 - mullets (57 species) * Ambassidae Klunzinger, 1870 - Asiatic glassfishes (75 species) Until recently, this order was restricted to only the mullets, but phylogenetic studies support the Asiatic glassfishes (previously placed as ''incertae sedis'' within the Ovalentaria) being their closest relatives. The order is thought to be the sister group to the Blenniiformes. Other authors instead treat this order as a clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... within an expanded Blenniiformes, and also find the Congrogadidae to be allied with the mullet-glassfish clade. References ...

Cichliformes
Cichliformes is an order of fishes. Its members were previously classified under the order Perciformes, but now many authorities consider it to be an independent order within the subseries Ovalentaria. The earliest fossils are known from the Eocene. Taxonomy There are three families within the Cichliformes; the leaffishes are a small family consisting of 4 genera and 5 species, the convict blennies are a small family consisting of a single genus and two species, while the cichlids are one of the largest vertebrate families with over 202 genera and more than 1700 species. These families look physically dissimilar from one another, with only molecular data revealing their close relationships. The following taxonomy is based on the Catalog of Fishes (2025) * Polycentridae T. N. Gill, 1858 (leaffishes) * Pholidichthyidae D.S. Jordan, 1896 (Convict blennies) * Cichlidae Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, o ...

Stiassnyiformes
Stiassnyiformes is an order of bony fish (Teleostei) proposed in 2009.Blaise Li, Agnès Dettaï, Corinne Cruaud, Arnaud Couloux, Martine Desoutter-Meniger, Guillaume Lecointre: ''RNF213, a new nuclear marker for acanthomorph phylogeny.'' Molecular Phylogenetics and Evolution, Volume 50, Issue 2, February 2009, Pages 345-363 It includes the mullets (Mugilidae), the Atheriniformes, the Beloniformes, the Cyprinodontiformes and some families of the paraphyletic Perciformes, including the cichlids. The new taxon was named by the authors of the first description in honor of the curator of the Department of Ichthyology at the American Museum of Natural History Melanie Stiassny, which suggested in 1993 that the mullet are allied with damselfish and guppies.Melanie L. J. Stiassny: ''What are Grey Mullets?'' Bulletin of Marine Science, Volume 52, Number 1, January 1993, pp. 197-219(23Abstract/ref> The close relationship of these outwardly different groups is based on molecular studies and ...

Atherinomorpha
The Atherinomorpha is a clade of fishes in the superorder Acanthopterygii, the ray-finned fishes, consisting of three orders. The clade is ranked as an infraseries within the subseries Ovalentaria, which in turn is ranked within the wider Percomorpha clade. Characteristics The species within the infraseries Atherinomorpha are generally small fishes which normally grow no longer than , although some needlefishes from the order Beloniformes can grow as long as . The testes of the males are of the restricted spermatogonial type, in which the testes change to reflect a seasonal pattern of reproduction. The females lay demersal eggs with filaments on the chorion. They may or may not have spines in their fins but where these are present they are generally weak. The number of vertebrae is normally less than 24. The pelvic fins are positioned abdominally, subabdominally, or thoracically and may be connected to the pleural rib by a ligament. Ctenoid scales may be present but this is rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percomorpha
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including Scombroidei, tuna, Syngnathiformes, seahorses, gobies, Cichlidae, cichlids, flatfish, Labridae, wrasse, Perciformes, perches, Lophiiformes, anglerfish, and Tetraodontiformes, pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant Vertebrate, vertebrates. Evolution Percomorpha are the most biodiversity, diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic Era (geology), era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous–Paleogene extinction event, Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early Tetraodontiformes, tetraodontiforms ''Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slov ...
