Large, sturdy horizontal tail flukes serve as the primary propulsive mechanism. Rapid up-and-down movements generate thrust.
Flexible, muscular bodies allow sideways undulations for agile navigation through narrow channels and around obstacles.
Two pairs of flippers adjust angle and position for steering, stability, and speed control.
Head tilting and turning enhance sensory perception and environmental awareness.
High-frequency clicks create mental maps of murky surroundings, enabling collision avoidance and efficient navigation.
This combination of powerful tail, flexible body, controlled flippers, and echolocation makes Amazon river dolphins exceptionally adept in their complex habitat.
