Giga-Tube Uktank

The giga-tube uktank split from its ancestor and evolved from walking uktanks that lost that drifted too far to the east and north and ended up on the shores of the mainland. They are slightly smaller than their ancestors and have many different features. Like its ancestor it must live an amphibious lifestyle and must go back into the water. In order to be able to stay out of the water it has a massive hollow shell in which it will fill with compressed oxygen. It gathers this for most of the day while in the water. It also have many breathing holes in its shell in order to fill it with oxygen, which are closed with membranes during its time outside the water. It still reproduces in the water and lays eggs in the water. They flock in masses once every full moon near the beach at shallow waters in Ovi Coast and Clayren Coast for a mass reproduction ritual. Most of their time on land is spent on feeding. Its has a much more varied diet now and feeds on all the flora on the coasts, and mainly on the rustballs. Their tube mouth is now much much larger. On the end has whats left of their hollow tooth, is now only a bony ring. This tube can suck in air to bring in the food even though their is not used for respiration. In addition to bringing food in they can use this to create sound from the tube mouth, usually powerful low sounds. They have a primitive ear using the front shell plate. This plate picks up the sound and the vibration is translated to the brain as noise. Thus with a way to make sound and hear sound they will communicate with each other while on land. When they feed on the rust stickyglobes they first inject liquid iron rich compounds into the spheres using a specialized part in their cutting claw making them heavier and fall on the ground, sometimes even breaking off. Then it cuts in the sticky budding connections into separate spheres. Finally it sucks the whole spheres into its tube and digests them inside its body. Its shell is reinforced with this iron as well.
