class bony fish

Class Osteichthyes includes all bony fishes. Like all fishes, Osteichthyes are cold-blooded vertebrates that breathe through gills and use fins for swimming. Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils.

What are the 2 classes of bony fish?

The bony fish are divided into two classes: ray-finned fish and lobe-finned fish. The bony fish are characterized by a lung or swim bladder, a cover over the gills, and bones covering the head and pectoral girdles.

What class do bony fish belong to?

Bony fish, (superclass Osteichthyes), 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.

What are the 5 classes of fish?

Summary. There are about 28,000 existing species of fish, and they are placed in five classes: hagfish, lampreys, cartilaginous fish, ray-finned bony fish, and lobe-finned bony fish.

What are the characteristics of class osteichthyes?

Key features of Osteichthyes

• Skeleton more or less bony, vertebrae numerous.
• Skin with mucous glands and embedded dermal scales.
• some without scales.
• Paired fins.
• Mouth with many teeth (some toothless).
• jaws present.
• Respiration by gills supported by bony gill arches and covered by a operculum.

What are 3 characteristics of bony fish?

Bony fishes share several distinguishing features: a skeleton of bone, scales, paired fins, one pair of gill openings, jaws, and paired nostrils. Osteichthyes includes the largest number of living species of all scientific classes of vertebrates, more than 28,000 species.

Are bony fish jawless?

Scientists group fish into three main types. They are divided into these groups because of the structure of their mouths and the types of skeletons they have. There are jawless fishes, cartilaginous (cart uhl AJ uh nuhs) fishes, and bony fishes. ... They also do not have pairs of fins like most fish.

What makes a bony fish a bony fish?

Bony fish differ from fish like sharks and rays in the chondrichthyes class. Instead of cartilage, bony fish have bones. ... The swim bladder is a gas-filled sac that helps keep bony fish buoyant! They have paired pectoral and pelvic fins, and all but a few species have bones in their fins.

Do bony fish have lungs?

Many species of bony fishes have a gas-filled bladder called a swim bladder. Apparently the swim bladder originally developed in fish as an organ of respiration, as evidenced by the "lung" of the lungfishes. In modern bony fishes that possess a swim bladder, the organ serves principally in maintaining neutral buoyancy.

Is tilapia a bony fish?

Examples of bony fish include:

Tuna. Tilapia. Herring. Catfish.

How do you classify fish?

Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes).

Are fish animals Yes or no?

Bird Classification

An animal is a land mammal other than a human being. Insects, birds and fish are not animals. Animals live in marine and terrestrial environments. Insects, birds, and fish are all animals.

Are most fish bony?

Most of the world's fish species are categorized into two types: bony fish and cartilaginous fish. ... The cartilaginous fish include sharks, skates, and rays. Virtually all other fish fall into the class of bony fish which includes over 50,000 species.
