How does the lumpfish compensate for lacking a swim bladder?
Answer
It uses its powerful sucker disc to maintain position against strong currents.
Lacking a swim bladder means the fish cannot achieve neutral buoyancy easily; therefore, its anatomical adaptation—the sucker disc—is crucial for maintaining its position, especially in high-flow environments.
