Which specialized anatomical structure allows Clarias batrachus to gulp atmospheric air and survive outside of water?
Answer
A labyrinth organ
The walking catfish possesses a specialized, highly vascularized accessory breathing organ known as a labyrinth organ. Located in the chambers above the gills, this complex, tree-like structure functions much like a primitive lung, enabling the fish to extract oxygen directly from the air to survive in oxygen-depleted environments.
