Following the answer to my question about an Anatomically correct Quetzalcoatl, is problematic have gravity center positioned so far behind the wings.So in the case of a creature with a snake-like tail this could impide the flying or at least a good gliding. But currently were many animals that were flying and had long tails like the Rhamphorhynchoidea pterosaurus or the maniraptorians previous to the birds, but what happen with this, well then eventually the natural selection favors specimens with a short tail and other ways to get a rudder.
So for keep the tail the benefit of have this should be better than lose the tail and that is the principal problem.
I thought some possible solutions based on keep the tail funtional, for that, but I am not sure about the physics and biomechanics
- Probably can not be an active flying, so a long gliding will be the only one option, so would be good a displacement of many houndreds of meters.
- When winding it could use the flexible part of its body to propel itself like a spring, strong enough to propel itself some tens of meters maybe 15-20, then it could use its wings, which although inefficient, enough to get a little more height and then the gliding.
- Should not be heavy as other animals of the same length, compared with a python or anaconda 150-250 kg for 5 meters, so probably need hollow bones (complicating even more the evolutionary ancestry of this creature but topic for another question).
I would like to make a redesign considering more the tail, that is the reason i have sectioned the original question.
Maybe my idea of a spring like throwing is completely useless or physically impossible, so maybe you can think other alternatives.
So, how the long and flexible tail can be keep useful at flying animals?
