Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
This article contains a list of all of the classes and orders that are located in the phylum Chordata. The subphyla Tunicata and Vertebrata are in the unranked Olfactores clade, while the subphylum Cephalochordata is not. Animals in Olfactores are characterized as having a more advanced olfactory system than animals not in it.
Class Cephalaspidomorphi - lampreys; Superclass Gnathostomata Vertebrates with jaws Class Chondrichthyes (cartilagineous fish - sharks and rays) Class Osteichthyes (bony fish), which has two subclasses: Actinopterygii (ray-finned fish) Sarcopterygii (lobe-finned fish) Full details of higher order fish taxonomy can be found in the Chordata article.
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 ]
Bony fish include the lobe-finned fish and the ray finned fish. The lobe-finned fish is the class of fleshy finned fishes, consisting of lungfish and coelacanths . They are bony fish with fleshy, lobed paired fins, which are joined to the body by a single bone. [ 12 ]
Following the convention of the major fish classification organizations (Fish Base, ITIS, Encyclopedia of Life), the Indostomidae are currently placed in the Gasterosteiformes. Morphological traits uniting the flying gurnards (Dactylopteridae) and the Syngnathiformes have long been noted. [10] Most authors, however, placed them with the ...
