Desert Uktank

The desert uktank split from its ancestor the rusty uktank. It has adapted to a more arid environment. It has shrunk to half its size for more maneuverability and has more scaly skin to help it from loosing water. In addition to that it will sleep in the river during the day and feed on land during the night.

It has developed a symbiotic relationship with the airstrainer, which is a decedent of the pallenidust. It grows in the breathing holes of its shell. There it can absorb water from the river and air and store up in the shell for both to absorb. It also absorbs the CO2 from the desert uktank while giving off O2 back to the desert uktank to breathe. This helps it last longer when venturing onto land to eat. While the airstrainer cannot photosynthesizes at night it can at dawn and dusk when the desert uktank is either going to eat or coming back from eating.

They have a slow metabolism and move very slowly. This is so they do not use up too much oxygen when feeding on land. Their large eyes help them see in the dark and its head plate can pick up sounds to hear. They will also stay in herds when feeding to help each out look out for night predators. They can only go about 3 miles from the river since they move so slow and need to get back to the river to refill their shell-tanks.To get even more water, they extract it from their food. The desert flora is very spare after the eruption so they will also eat some river flora as well.
