- Characteristics and Classification of Bony Fish: Some documents refer to the bony fish as the Osteichthyes, which used to be recognized as a class of organisms. Osteichthyes is still used commonly to refer to the two main types of bony fish: 1  Ray-finned fishes, or Actinopterygii.2  Lobe-finned fishes, or Sarcopterygii, which includes the coelacanths and lungfishes.haracteristics and Classification of Bony Fish: Some documents refer to the bony fish as the Osteichthyes, which used to be recognized as a class of organisms.

- Cartilaginous fish (scientific name Chondrichthyes) have a skeleton made from cartilage instead of bone. Cartilage is tough and flexible and provides enough structural support to allow these fish to grow to very large sizes.Cartilaginous fish include sharks, rays, skates and chimaeras.There are approximately 600 different species of rays and skates and about 500 shark species. Rays and skates live in oceans throughout the world. Most rays and skates live on the bottom of the ocean while some live in open water.artilage is tough and flexible and provides enough structural support to allow these fish to grow to very large sizes.

Osteichthyes Osteichthyes /ˌɒstiːˈɪkθi.iːz/ , also called bony fish, are a taxonomic group of fish that have bone, as opposed to cartilaginous, skeletons.The vast majority of fish are osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species.steichthyes are divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 420 million years ago, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes.

DNA study shows Celts are not a unique genetic group We did not find a single genetic group corresponding to the Celtic traditions in the western fringes of Britain. The researchers did see distinct genetic groups within those regions but those groups were quite different from each other, according to Prof Donnelly.

Osteichthyes The vertebrates include various animal groups such as fish, amphibians, reptiles, birds, and mammals. A fish pertains to any gill-bearing animals lacking limbs with digits. Osteichthyes (bony fish) is one of the taxonomic superclasses of fish. The others are chondrichthyes (cartilaginous fish) and Agnatha (jawless fish). Osteichthyes includes the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii).

Why These European Countries Don't Use the Euro Here are a few reasons why many EU nations don’t use the euro. 1  Independence in Drafting Monetary Policies: Since the European Central Bank (ECB) sets the economic and monetary policies for all eurozone nations, there is no independence for an individual state to craft policies tailored for its own conditions.

Ray-finned Fish - Actinopterygii The fins are supported by rays, as the name indicates. In contrast to the cartilaginous fish they have a rigid skeleton.The swim bladder is also a unique feature of most ray-finned fish, enabling them to maintain buoyancy as they move up or down in the water.A gill cover is used to pump water through the gills, enabling the bony fish to breathe without swimming.he fins are supported by rays, as the name indicates. In contrast to the cartilaginous fish they have a rigid skeleton.

Differences between sharks and bony fish: more than just the skeleton Shark species have eyelids and some can even protect their eye with a tough third eyelid called a nictating membrane. Other species, like the great white shark, have muscles that can roll the eye back into the socket for protection. Bony fish lack eyelids or the ability to protect their eyes.lthough the two groups once shared a common ancestor, there are several major biological differences between them. Teleosts, the bony fish, are some of the most abundant vertebrates on the planet with nearly 25,000 living species. In contrast, the chondrichthians represent only about 1,100 species of extant species of.

- This group includes sharks, rays, skates and the chimaeras. All the fishes in this group have a skeleton made of cartilage instead of bone like most other fishes. Cartilage is similar to bone but it lacks the chemical that makes bone hard. Your nose and ears are strengthened by cartilage rather than bone.

Ray-Finned Fishes, Lobe-Finned Fishes, and Sharks! Ray-Finned Fishes, Lobe-Finned Fishes, and Sharks! 2 Comments. The cartilaginous fishes are a group of about 1,000 species and share many things in common, including the presence of jaws, paired fins, a two-chambered heart, and bodies made of cartilage. By far the largest group of fish are the bony fish. Eight species of bony fish make up a small group called lobe-finned fish, including the lungfish, a fish with the ability to breathe air, that can even drown if it is kept in water too long. Another 27,000 species make up the ray-finned fish. Remember from above that there are a total of slightly less than 58,000 species of all vertebrates. It is clear that bony, ray-finned fish are the most common vertebrates. The lungfish is one of only eight species of lobe-finned bony fish.
