Actinopterygii (ray-finned fish) Sarcopterygii (lobe-finned fish, including tetrapods) Osteichthyes (/ ˌɒstiːˈɪkθiːz / ost-ee-IK-theez), [2] also known as osteichthyans or commonly referred to as the bony fish, is a diverse superclass of vertebrate animals that have endoskeletons primarily composed of bone tissue.
Osteichthyes (bone-fish) or bony fishes are a taxonomic group of fish that have bone, as opposed to cartilaginous skeletons. The vast majority of fish are osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, with over 435 families and 28,000 species. [21] It is the largest class of vertebrates in existence today.
Leedsichthys is the largest known member of the Osteichthyes or bony fishes. [20] The largest extant non-tetrapodomorph bony fish is the ocean sunfish, Mola mola, being with a weight of up to two tonnes an order of magnitude smaller than Leedsichthys. The extant giant oarfish might rival Leedsichthys in length but is much thinner.
Leedsichthys, a giant Jurassic pachycormid. This list of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class Osteichthyes), excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now ...
A subclass of the Osteichthyes, the ray-finned fish (Actinopterygii), have become the dominant group of fish in the post-Paleozoic and modern world, with some 30,000 living species. The bony (and cartilaginous) fish groups that emerged after the Devonian were characterised by steady improvements in foraging and locomotion.
Euteleostomi (Eu- teleostomi [a], where Eu- comes from Greek εὖ 'well, good' [b] or Euteleostomes, also known as "bony vertebrates " [c]) is a successful clade that includes more than 90% of the living species of vertebrates. Both its major subgroups are successful today: Actinopterygii includes most extant bony fish species, and ...
Lungfish. Lungfish are freshwater vertebrates belonging to the class Dipnoi. [1] Lungfish are best known for retaining ancestral characteristics within the Osteichthyes, including the ability to breathe air, and ancestral structures within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton.
The phylogenetic classification of bony fishes is a phylogenetic classification of bony fishes and is based on phylogenies inferred using molecular and genomic data for nearly 2000 fishes. [1][2][3] The first version was published in 2013 and resolved 66 orders. [2] The latest version (version 4) was published in 2017 and recognised 72 orders ...
