What specialized function does the laterally compressed tail of *Pelamis platura* serve in its pelagic existence?
Answer
It acts as a paddle, aiding in steering and maneuvering in the water column.
The tail of the Yellow-bellied Sea Snake exhibits extreme specialization for aquatic movement, being laterally compressed into a shape resembling an oar or paddle. This modified structure is crucial for providing directional control, maneuvering through the water column, and assisting with propulsion alongside the main body movements. This modification is a defining feature that distinguishes it from terrestrial reptiles and facilitates its life in open water.
