Interesting. But skyglider tail "fin" is vertical, not horizontal.
But to spend entire life in air creature must have either very large wing surface comparing to body weigth (like swift), or be as light as air. This is a picture showing how much lighter than air gas is needed to lift a human a57.foxnews.com/static.foxnews⦠So skygliders would need to have alike big hydrogen ballon inside them to be able to really fly and spend entire life in air. Of course rubber from these ballons also have its own weight and skyglider would have muscles and skin instead of that rubber, but still, its internal ballon must be very big to work efficiently.
Thats the problem with skyglider in earth atmosphere. When i First drawed them, their balloons were much smaller compared to rest of the body. And later I seen picture like this, how big ballon is needed to lift a human. And I understood, that balloon must occupy more than 95% of skyglider body volume to enable it to float in air. Of course in denser atmosphere balloon could be much smaller to lift animal, but on Earth atmosphere density have no chances to change significantly.

Well, jaws are very important bones. Without it its hard to catch food.

Jaws are most univesal food processing organ. Of course they can be modified for example into piercing-sucking organ like mosquito or spiders have, but it would limit availible food to very specialized ones, like blood, tree sap or nectar. Jaws enable to eat various food, like various small animals, fruits or even leaves. And they would not make swallowing prey too hard. Birds have no problem with swallowing big prey. Shipworm is not very active and dont need much energy, but skygliders would have big energy needs.

But what cells with hydrogen would help? I guess muscles with hydrogen bubbles in them probably would be lighter, but also more soft and weaker. Whole body would become very sponge like and easy to rip apart. Single ballon, which can be used as animal skeleton can work better. Something like this: www.youtube.com/watch?v=jPGgl5β¦
As flattened they would have very little controll of their flying direction, they would be carried by wind. Fish shape would enable them to actively propel themselves in air.

Well, i guess yes, but balloon occupies almost entire their body and is much bigger comparing to all other organs. In fact they are more like ballon with tiny organs on its lower side than animal with ballon inside them.

Rather expand area of balloon. Look how little cabin of the zeppelin (or in this case blimp) is compared to ballon: upload.wikimedia.org/wikipedia⦠Skygliders would need very similar proportion between organs and baloon, like this blimb has between cabin and baloon.

To push something from the air quite large surfaces are needed. I dont thing it would be possible for them to move with skin contractions. And idea is they had vertical feathery sail on tail before they managed to control direction they fly.
