Which fins are primarily utilized by *Clarias batrachus* for terrestrial locomotion?

Stiff, strong pectoral fins

While the long dorsal and anal fins contribute significantly to propulsion during aquatic swimming, the distinct ability of the walking catfish to move on land relies heavily on its pectoral fins. These fins are described as being stiff and strong, functioning effectively like a pair of front legs. By using these pectoral fins, the fish is capable of lifting its body off the ground, allowing it to employ a wriggling motion to advance across mud or other damp surfaces. This terrestrial movement is typically motivated by environmental stressors such as rapidly drying ponds or dangerously low dissolved oxygen levels in the water.
