How is the white shark's caudal fin typically structured regarding lobe size?
Answer
The upper lobe is typically larger than the lower lobe.
Propulsion for the white shark comes primarily from its caudal fin, also known as the tail fin. A key structural detail that differentiates it from many bony fish is that the white shark's tail is slightly asymmetrical. Specifically, the upper lobe of the caudal fin is generally larger than the lower lobe. This asymmetrical structure is fundamental to how the shark moves, as it generates the necessary powerful side-to-side sweeps required to drive the massive animal forward through the water column efficiently.
