Airbulb

The airbulb has replaced its ancestor, the gildbowl, living in the scrublands and the western sections of the polar beach. The continuation of the Oathinian Explosion, along with two and a half million years of the ruthless natural selection that comes with such a harsh climate, has changed the airbulb's physical characteristics markedly, although its basic anatomy is much like its ancestor's. Unlike its amphibious ancestor, the airbulb is fully adapted to a land-based life. Its stalk has grown longer, and has a stem with an outer coating slightly stronger than the main bulb, to protect against predators such as the wanderer. It has also grown much larger than its ancestor, and is now visible to the naked eye at one millimeter. The most remarkable change, though, is the development of three, smaller membranes instead of a single large one. Another advantage, the one that gives it its name, comes from the continued relation with the nitroids. During the three week long summer, it will supply the nitroids with nutrients, allowing them to produce the gaseous ammonia that fills its bulb, and keeps it bouyent. During the winter, though, when the darkness causes extreme cold ,the nitroids will stop producing ammonia, causing the bulb to shrink. The shape of the bold causes it to flatten, and the organism, under the weight of the bulb, allows the organism to stay close to the ground, dissapating less heat. At the end of summer, the bulb will break at the top, releasing spores into the wind, ready to grow when sunlight returns.
