Farmphibian

The farmphibian replaced its ancestor the rootdigging thornback. With its relatives filling the same niches it had to find a new niche. It also was poorly adapted to the cold and dry polar environment it lived in and had little protection from predators. To cope with this it would hide inside the Giant Hollowdome by gnawing into them with their strong jaws. Inside they were protected from predators as well as kept warm from the greenhouse-like environment inside. However they had to go through island dwarfism before they could fit inside the 30 cm wide giant hollowdome. And even then adults are a bit cramped inside.

The water filled center of the giant hollow dome is perfect for a nursery pool for their tadpole-like larva. However they have to gnaw a hole in it and maintain the hole until the offspring are large enough to leave the pool. After they leave the pool the giant hollowdome will grow back over the hole with minimal damage. Offspring are laid in the spring and leave the pool by summer.

As adults they create their own little greenhouse garden inside the giant hollowdome. Their dung contains the seeds and spores of many small flora and as a result grow specifically inside giant hollowdome. These new species mainly come from the genus group of marbleflora, pioneeroots, sapshrooms and supershrooms. Which in turn are the food of the farmphibian. Sapshrooms typically grow on the support pillars of the dome while supershrooms grow in the fresh dung. Then marbleflora and pioneeroots grow in the composted soil. All sorts of microbes also live within the soil and dung too.

When it gets too crowded inside their birth domes, they will seek out new giant hollowdomes. They do this in the summer when they can survive outside the protection of the domes. However there are predators who would like to eat them. So they have developed many spines down their backs and they can quickly sprint when warm enough. Those those already inside domes will defend off others who want to take over it themselves. Thus the strongest males will have the best domes. Females will seek out males with the best domes. A male can have a harem of around 2 to 3 females since there is not much room for more.

In the long dark winters they will hibernate in the safety of the domes. When the snow begins to thaw they will wake up and females will lay their eggs in the nursery pools. Like their ancestors they are deaf and have color patches on their cheeks in which they use to communicate with each other. Their eyes have also improved as well to look out for predators and they even have developed eye-lids to protect their eyes.
