This is a Millipedaetankus, a semi-common animal that we can find in some part of the desert on Alpha Centauri. They are herbivorous, and the Security Forces there have made a few genetic changes to these animals to use them as intervention vehicles againt anti-government rebels on Alpha Centauri, for its ability to project in bursts such large balls of compacted grass much like our flashball on earth. It's a really effective non-lethal weapon to stop protesters in demonstrations. And before I forget, yes their skin is semi-transparent, which allow us to see how they are made inside !
