	Osteichthyes - Wikipedia, the free encyclopedia
		Class Osteichthyes are the bony fish, a group paraphyletic to the land vertebrates, which are sometimes included.
		The vast majority of fish are bony fish, and therefore belong to class Osteichthyes.
		Based on the number of species, Osteichthyes are the most successful group of vertebrates.

		Fishes not included in the Osteichthyes are the Chondrichthyes (sharks and their relatives), the Myxini (hagfishes), and the Cephalaspidomorphi (lampreys).
		The subclass Dipnoi (lungfishes) is characterized by an upper jaw fused to the braincase, fused teeth, and the presence of an air-breathing organ that opens to the esophagus.
		All four living classes of fishes and the three major groups of Osteichthyes were established by the mid-Devonian.

		Osteichthyes are the bony fish, a group paraphyletic to the land vertebrates and which sometimes includes them.
		The Osteichthyes were traditionally treated as a class of vertebrates, with subclasses Actinopterygii and Sarcopterygii, but newer schemes may divide them into several separate classes such that Actinopterygii and Sarcopterygii are now a class in themselves (what you are being taught).
		Keeping the old Class Osteichthyes then became problematic as this group was paraphyletic and the current goal is to represent monophyletic groups.

	Bony Fish - Class Osteichthyes
		The common name "fish" refers to four different classes, depending on the person classifying them (there are numerous different ways to classify fish).
		The class Osteichthyes is made up of 26000 species of bony fish.
		These are all the common fish and eels found in both salt and/or fresh water.

	Palaeos Vertebrates 90.200 Teleostomi: Osteichthyes
		The Devonian is frequently called, with ample reason, the "Age of Fishes." The stage for this explosion of aquatic vertebrates was undoubtedly set in the Silurian, perhaps due to the duplication of ancestral hox genes.
		But, whatever the cause, the earliest Devonian saw the rapid development of chondrichthyans, placoderms, acanthodians, and the two most successful groups of vertebrates ever known: the actinopterygians and sarcopterygians -- collectively, the bony fish, the Osteichthyes.
		Note: some of the features in the "description" section are taken from Lund's (2000) synapomorphies of his "basal node" (#23) which is probably not quite Actinopterygii, but close, probably corresponding to the Late Devonian crown group of actinopterygians.

		The Osteichthyes are incredibly diverse and constitute over 75% of all "fishes".
		Nonetheless, Osteichthyes usually have a skeleton, or part of the skeleton, made of true cellular bone, a premaxilla and maxilla in the upper jaw, usually segmented fin rays ("lepidotrichia"), and some kind of gas bladder (may be modified into a lung in some groups).
		The Osteichthyes consist of two major sublineages: the lobe-fined fishes (Sarcopterygii) and the ray-fined fishes (Actinopterygii).

		In male viviparous Osteichthyes spermatozeugmata are also formed.
		In the guppy, Poecilia reticulata, spermatozeugmata are ovoid to rounded structures measuring 135-235 µm in diameter.
		In some viviparous Osteichthyes, in particular the poeciliids and halfbeaks, sperm are stored within folds of the inner ovarian epithelium.

		One subset of Gnathostomata is Osteichthyes, bony vertebrates
		So it appears that gnathostomes (jawed vertebrates) diverged at some point in the late Silurian or early Devonian period, with chondrychthyes developing progressively more cartilage in their skeletons (except in the jaw of course) while lobe-finned fish used progressively more bone except where these hinge together.
		One subset of Osteichthyes is Sarcopterygii, bony vertebrates which have both lungs and legs.

		The earliest remains of the bony fish are found from the Lower to Middle Devonian.
		These remains were already of well diversified forms, with the fleshy-finned and ray finned types already separate, and it is believed that the Osteichthyes must have arisen at some time during the Silurian*.
		The distinguishing character concerns the structure of the paired fins.

		We only needed to know the common name for the Osteichthyes for the exam, but I included the genus and species here for the sake of knowledge.
		It can be identified by the edge of its anal fin because it is strongly curved, usually with 16 to 19 rays.
		Its lateral line is alternately fl and white and it can grow to be 40 cm in length (Robins and Ray 1986).
