Chitjorn

The chitjorn replaced its ancestor, the solumcrusta in Ittiz Bog and Ittiz River, then spread to Barlowe Tundra. Now that the river became colder it had to adapt to the colder environment. Its hard chitin shell keeps it insulated from the cold. It also has developed concentrated patches of photosynthetic cells along the grooves in its shell. Like its ancestor it covers the ground it sits on like a blanket. Its shell keeps in enough water that it can survive on land as well. However only when in the muddy thawing soil of soil in the tundra. During the winter they will hibernate until it becomes warm again.
