Bone Fish



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.
