Carp: example of bony fish
What they are - biological definition:
Scientifically known as osteictes (Westichthyes class), they are fish that have a skeleton formed predominantly of bones.
Summary of Key Features of Bone Fish
- They have bone skeleton.
- Most bone fish species have dermal bone scales. In some species (catfish, for example) absence of scales occurs. When scale loss occurs, the fish organism replaces it.
- Gills without spiracles and protected with operculum.
- Regarding habitat, they can be freshwater (live in freshwater) or marine (live in saltwater).
- No cloaca.
- Have swim bladder with the function of floating.
- Most bony fish have external fertilization, and the larvae are known as fingerlings. The development of these fish is indirect.
- Have small cone shaped teeth.
- Do not have salivary glands in the mouth.
- The circulatory system is closed.
- They have anterior mouth.
- Breathing may be through gills or lungs, depending on the species.
- Ammonia is the main element excreted by these fish.
