Crocodilian tails are laterally flattened to enhance swimming efficiency.
The gharial’s elongated tail contains powerful musculature that drives propulsion through lateral undulation. This tail can account for nearly half the animal’s total length. Unlike limbs, which play limited roles in aquatic movement, the tail generates thrust against river currents. Efficient propulsion allows sustained swimming across long stretches. Tail-driven locomotion complements the streamlined snout design for hydrodynamic efficiency. Damage to the tail can significantly impair survival. The structure functions as both engine and rudder.

In fast-flowing rivers, propulsion must overcome strong currents. The tail’s muscle mass provides both speed and maneuverability. Energy efficiency becomes critical during territorial patrols and prey pursuit. A compromised tail reduces hunting success and escape capacity.
The biomechanics of tail propulsion highlight integration between anatomy and environment. Rivers shaped the gharial’s body plan over millions of years. Altered flow regimes change the hydrodynamic context of that design. A powerful tail remains effective only when currents remain within evolutionary norms.
