Osteichthyes (/ ˌ ɒ s t i ˈ ɪ k θ i iː z /), popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue, as opposed to cartilage.The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species.
Bony fish, any member of the superclass Osteichthyes, a group made up of the classes Sarcopterygii (lobe-finned fishes) and Actinopterygii (ray-finned fishes) in the subphylum Vertebrata, including the great majority of living fishes and virtually all the world’s sport and commercial fishes.The scientific term Pisces has also been used to identify this group of fishes.
Osteichthyes - Bony Fish : This is the largest class of vertebrates. There are over 29,000 species of bony fish found in freshwater and marine environments around the world. Bony fish differ from fish like sharks and rays in the chondrichthyes class. Instead of cartilage, bony fish have bones. Bony fish also have a swim bladder. The swim ...
Most of the world's fish species are categorized into two types: bony fish and cartilaginous fish.In simple terms, a bony fish (Osteichthyes) is one whose skeleton is made of bone, while a cartilaginous fish (Chondrichthyes) has a skeleton made of soft, flexible cartilage.A third type of fish, including eels and hagfish, is the group known as Agnatha, or jawless fish.
Osteichthyes includes the largest number of living species of all scientific classes of vertebrates, more than 28,000 species. Osteichthyes account for about 96% of all fish species. Fishes not included in the Osteichthyes are the Chondrichthyes (sharks and their relatives), the Myxini (hagfishes), and the Cephalaspidomorphi (lampreys). Subclasses
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). ...
Bony fish typically have swim bladders, which helps the body create a neutral balance between sinking and floating. However, these are absent in many species, and have developed into primitive lungs in the lungfishes. Osteichthyes are primitively ecothermic (cold blooded), meaning that their body temperature is dependent on that of the water.
Some examples of bony fish include the devil firefish, the emperor angelfish, the emperor snapper, the pineapple fish and the garden eel. These bony fish represent only a tiny portion of the 28,000 species of bony fish in the scientific class Osteichthyes, which contains the largest number of living vertebrate species in the world.
Actinopterygii (/ ˌ æ k t ɪ ˌ n ɒ p t ə ˈ r ɪ dʒ i aɪ /), or the ray-finned fishes, constitute a class or subclass of the bony fishes.. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines ("rays"), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays ...
