Osteichthyes. Osteichthyes is defined as the most recent common ancestor of Actinopterygii and Sarcopterygii, and all of that ancestor's descendants. Osteichthyes is diagnosed by the presence of lungs (see below) and by most of the bony skeleton being formed from cartilaginous precursors. Many bony fishes have an elongated sac, the gas bladder. Osteichthyes is a class of jawed fishes having a bony endoskeleton. It is the largest class of vertebrates and includes a diverse group of marine and freshwater bony fishes. The other group of jawed fishes are cartilaginous fishes, which are included in the class Chondrichthyes الأسماك العظمية هي فوق طائفة من الأسماك تملك هياكل مكوّنة من العظام، على عكس الأسماك الغضروفية.الأغلبية العظمى من الأسماك هي أسماك عظمية، حيث إنها مجموعة شديدة التنوع والانتشار تتألف من أكثر من 29,000 نوع

Osteichthyes, known as the bony fish, are a taxonomic class (or superclass) of fish and the largest class of vertebrates in existence today. With over 26,000 species, they comprise over 95 percent of all fish species.The Osteichthyes include the ray-finned fish (subclass or class Actinopterygii) and lobe finned fish (subclass or class Sarcopterygii).. The osteichthyes, or bony fish, represent the largest taxonomic class of vertebrates in the modern world. Fish have evolved to manage essential life processes in water. This has produced particular tissue adaptations, such as gill and scales, and a variety of body forms to exploit various niches in the aquatic environment

Instead of cartilage, bony fish have bones. Bony fish also have a swim bladder Osteichthyes are a taxonomic superclass of fish, also called bony fish, that includes the ray-finned fish (Actinopterygii) and lobe finned fish (Sarcopterygii).The split between these two classes occurred around 440 million years ago.

Osteichthyes are characterized by a bony endoskeleton, in contrast to cartilaginous fishes or chondrichthyans (sharks, rays, and chimaeras). Bony fishes comprise the largest clade of vertebrates. Osteichthyes is a clade made up of two sister groups, the Actinopterygii and the Sarcopterygii, and the split between these two groups occurred very early after the evolution of bony fishes. And even the earliest fossil Osteichthyes are either actinopterygians or sarcopterygians Bony fish have a bony opeculum Cartilaginous fish have gill slits. 15. Class Osteichthyes • Swim Bladder - a gas-filled sac above the stomach allows for adjustments in buoyancy Upper and lower lobes of Caudal Fin almost always the same size. 16 Class Osteichthyes Lungfish, Coelacanth, Perch, Trout, Salmon Bony Fish. Bony fish have three key characteristics: bone; swim bladder (or lungs) scales; External Anatomy. All bony fish have a distinct head, trunk, and tail. On each side of the head is the operculum, a hard plate that opens ate the rear and covers the gills. Scales are thin.

The Huron Historic Gaol is a unique octagonal building which served as the County Jail from its opening in 1841 until 1972 The main difference between Chondrichthyes and Osteichthyes is that the Chondrichthyes is the class of bony fish whose endoskeleton is made up of cartilages whereas Osteichthyes is the class of cartilaginous fish whose endoskeleton is made up of bones.Furthermore, Chondrichthyes can only be found in marine water while Osteichthyes can be found in both fresh and marine water Traditionally, the Osteichthyes is considered a class, recognised on having a swim bladder, only three pairs of gill arches, hidden behind a bony operculum and a predominately bony skeleton.[9] Under this classification systems, the Osteichthyes are paraphyletic with regard to land vertebrates as the common ancestor of all Osteichthyes.
