Not specially. I imagine a lot of these wanderers of all shapes might exist. Statistically, that we have only seen one with such an unusual shape demands explanation. One possible reason would be that more conventional shapes are somehow hampered in their travels. My thesis is that a torpedo shape is relatively advantageous to objects traversing a fluid medium. I have no idea what fluid that might be.
