Carrymeobscuris ability to blend in with it's environment is thought to serve as a protective mechanism to camouflage it from predators... by assuming the colour of surrounding objects and using it's ability to mimic their shapes they are nearly invisible when they are still.
Population numbers are difficult to estimate because the
carrymeobscuris is such an elusive creature and very few of it's habits are known save for their attraction to dark tunnels and trains.
