Balloon Arch

The balloon arch split from it's ancestor. Because of the little competition, the balloon arch was able to get much larger than it's ancestor and can now get about 2.5 meters in length. To catch more sunlight, three of the hydrogen filled bubbles have become much larger and are now used only to capture as much sunlight as they can. The other bubbles are still used for reproduction and grow mainly on the lower side of the trunk, so noggers or other animals can feed on them.
