Duracrete Worm
found on Coruscant, these burrowing creatures had adapted to living within the duracrete walls of buildings. Measuring over three meters in length when fully grown, the duracrete worm actually fed on the duracrete which was used to form the foundations of many buildings. The feeding activity of the duracrete worm left many structures with dangerously eroded foundations, and many such buildings had to be imploded before they became hazards to intelligent beings.
