What adaptation allows fish to control their buoyancy?
-
Lateral line
-
Dorsal fin
-
Swim bladder
-
Gills
That's Correct!
It's Wrong!
The correct answer is "Swim bladder". The swim bladder is a gas-filled organ that enables fish to regulate their buoyancy, allowing them to ascend or descend in water without expending energy. This adaptation is crucial for maintaining stability and depth in aquatic environments. Other structures, like the lateral line or gills, have different functions related to navigation and respiration, respectively.
