Of course they live in a 3D environment. When we watch them under the 
microscope we see 2 dimensions only (3rd can be seen by turning the wheels, 
but it's rather thin since it's between slides). They also don't loook the 
way you see them, they have 3 dimensions themselves, and the reason you see 
inside of them is becase the membrane is transparent.
