they're bony u idiot
The three classes of bony fish are Actinopterygii (ray-finned fish), Sarcopterygii (lobe-finned fish), and Dipnoi (lungfish). Ray-finned fish have fins supported by bony rays, lobe-finned fish have fleshy lobed fins, and lungfish are known for their ability to breathe air.
The four types of lungfish are the south American lungfish, the African lungfish
Lungfish have 2 lungs but the Australian lungfish has 1.
Lungfish - band - was created in 1988.
Trout and lungfish share several similarities, primarily as they are both aquatic vertebrates that belong to the superclass Osteichthyes, or bony fish. They both have a streamlined body shape adapted for swimming, and they are ectothermic, meaning their body temperature is regulated by their environment. Additionally, both species exhibit adaptations for breathing in water, although lungfish possess lungs that allow them to breathe air when oxygen levels in water are low. These traits highlight their evolutionary adaptations to aquatic life.
Both jawless fish and cartilaginous fish have skeletons composed of cartilage and distinct brains. Also, some cartilaginous fish don't have scales, and all jawless fish don't have scales. Cartilaginous fish, however, have jaws, paired appendages, and a kind of vertebrae. Jawless fish do not have jaws, paired appendages, and often are without vertebrae.
Bony fish belong to the Class Sarcopterygii (if lobe-finned) and the Class Actinopterygii (if ray-finned). Coelacanths and lungfish are lobefinned and about all other bony fish are ray-finned. The two classes used to be combined as Class Osteichthyes. There are many superorders and orders in the bony fish classes.
Lungfish can breathe through air.
three years can lungfish live out of water...
yes all vertabrea have ewars
usually 98 but the oldest Australian lungfish is 123
