How does the terrestrial locomotion of the desert armored catfish differ from Clarias batrachus?

The desert armored catfish has been observed using a more primitive, serpentine or looping motion

Comparative analysis of different fish species capable of terrestrial movement provides insight into varying evolutionary strategies for solving the same environmental problem. When contrasting the movement of the walking catfish, which appears to leverage its pectoral fins in a somewhat organized gait when possible, with the desert armored catfish, a distinct difference in methodology is noted. Observations indicate that the desert armored catfish employs a locomotion strategy described as a more primitive, serpentine, or looping motion when moving across land. This contrast suggests that the utilization of pectoral fins for directed thrust is a specific advancement found in *Clarias batrachus* compared to other catfish lineages.
