-Bony fish have a special adaptation,that allows them to remain buoyant, or float on water.
-They have a special organ called a swim bladder, which is under the layer of bony skeleton and filled with gas.
-Bony fish are able to breathe without swimming through their Operculum. This is a flap on each side that covers the gills.
-Bony fish have color vision. They use this to locate food, find mates and avoid predators.

-The important aspects of bony fishes senses function as follows:
- Hearing: The hearing range extends from 200 to 180,000 Hz, depending on the depth of the water the bony fish live in and what they're using sound for (usually to detect or avoid prey). There are no external openings as their are in humans. Sound waves travel to the ears through soft tissue, which has about the same acoustic density as water. Sound travels through water, four times faster than it does through air!
- Vision: Bony fish who live in shallow water tend to have smaller eyes and, some scientists believe,color vision. Bony fish who live in deep water tend to have larger eyes. Some species have no eyes. They use other senses to find prey.
- Smell: This sense is well-developed, but can also vary among species.
- Taste: Bony fish have taste buds in their mouths. Some species can detect sweet, bitter and salty. Taste may be why some prey items are accepted or rejected.
