Summary Introduction

To write:

The manner a swim bladder helps a fish maintain its depth.

Introduction:

Fishes live in aquatic habitats like lakes, seas, rivers, ponds, etc. Some fishes live in complete darkness at the bottom of the deep ocean whereas others live in the freezing water of the Polar Regions and have special proteins in their blood to keep the blood from freezing. There are about 24,600 species of living fishes are found.

Explanation of Solution

The swim bladder is an internal organ of fishes. It is filled up with gas. When gases diffuse out of the swim bladder, a fish can sink. When gases from the blood diffuse into the swim bladder, a fish can raise in the water column. The swim bladder regulates the buoyancy of many bony fishes. Swim bladder allows a fish to control its depth.

Conclusion

Thus, the swim bladder can help the fishes to control its depth. The swim bladder can also regulate the buoyancy of many bony fishes.
