What animals are classified as Osteichthyes?
Class – Osteichthyes
Class Osteichthyes includes all bony fishes. Like all fishes, Osteichthyes are cold-blooded vertebrates that breathe through gills and use fins for swimming.
What is the class of Osteichthyes?
Osteichthyes is a class of fishes included in the division Gnathostomata, which includes all the vertebrates having jaws. Jawless fishes are included in the division Agnatha and the class Cyclostomata. Gnathostomata is divided into two superclasses, viz. Pisces (having fins) and Tetrapoda (bear limbs).

What is the difference between Chondrichthyes and Osteichthyes?
The primary difference between these two classes is that members of class chondrichthyes have their skeletal system made of cartilage while members of class osteichthyes have a skeleton made of bone tissue.
What are three examples of Osteichthyes?
Example of Osteichthyes: Queensland lungfish and West Indian Ocean coelacanth (two Sarcopterygii), Iridescent shark and American black sturgeon (two Actinopterygii). Osteichthyes can be compared to Euteleostomi. In paleontology the terms are synonymous.

Which of the following characteristics is shared between Chondrichthyes and osteichthyes?
Common characteristics between Chondrichthyes and Osteichthyes: Both of these are aquatic fishes and belong to the class Pisces. Respiration in both of these groups occurs through gills. Both of these groups of fishes are cold-blooded or poikilotherms.
What are the 3 types of bony fish?
Most species of bony fishes are covered with and protected by a layer of plates called scales. There are four different kinds of bony fish scales: cosmoid, ganoid, cycloid, and ctenoid. True cosmoid scales are found only on extinct Crossopterygians.
What are the 7 levels of classification for a bird?
In taxonomy, organisms are given a name for each level of classification. The eight levels of classification are domain, kingdom, phylum, class, order, family, genus, and species. All birds are given the following levels of classification: Eukaryote, Animalia, Chordata, Aves.
Why are birds classified as reptiles?
Reptiles are vertebrates that have scales on at least some part of their body, leathery or hard-shelled eggs, and share a number of other features. Snakes, lizards, turtles, crocodilians, and birds are reptiles. Like all vertebrates, reptiles have bony skeletons that support their bodies.

Are birds reptiles or avians?
reptiles
Ask your average paleontologist who is familiar with the phylogeny of vertebrates and they will probably tell you that yes, birds (avians) are dinosaurs. Using proper terminology, birds are avian dinosaurs; other dinosaurs are non-avian dinosaurs, and (strange as it may sound) birds are technically considered reptiles.
