Sarcopterygii (/ ˌ s ɑːr k ɒ p t ə ˈ r ɪ dʒ i. aɪ /; from Ancient Greek σάρξ (sárx) 'flesh' and πτέρυξ (ptérux) 'wing, fin') — sometimes considered synonymous with Crossopterygii (from Ancient Greek κροσσός (krossós) 'fringe') — is a clade (traditionally a class or subclass) of vertebrate animals which includes a group of bony fish commonly referred to as lobe ...
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.
Eusthenopteron (from Greek: εὖ eû, 'good', Greek: σθένος sthénos, 'strength', and Greek: πτερόν pteron 'wing' or 'fin') [2] is a genus of prehistoric sarcopterygian (often called "lobe-finned") fish known from several species that lived during the Late Devonian period, about 385 million years ago.
No quantitative dietary data are available, but anecdotal observations clearly indicate the diet of the lungfish changes with development. This is proven to be correlated with a change in dentition. Lungfish larvae are bottom feeders. They eat micro-crustaceans and small Tubifex worms, occasionally supplementing their diets with filamentous ...
This list of lobe-finned fish is a comprehensive listing of all genera that have ever been included in the class Sarcopterygii, excluding purely vernacular terms and tetrapods. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ( nomen dubium ), or were not formally published ( nomen nudum ...
Rhizodus (root tooth) is an extinct genus of basal, finned tetrapodomorphs (the group of sarcopterygians that contains modern tetrapods and their extinct relatives). It belonged to Rhizodontida, one of the earliest-diverging tetrapodomorph clades.
Latimeria is a rare genus of fish which contains the two only living species of coelacanth.It includes two extant species: the West Indian Ocean coelacanth (Latimeria chalumnae) and the Indonesian coelacanth (Latimeria menadoensis).
Ceratodontiformes is the only extant order of lungfish, containing the families Neoceratodontidae, Lepidosirenidae, and Protopteridae as well as many other extinct groups. . Members of this group are the only lungfish known to have survived the Permian-Triassic extinction eve
