Such a 2D animal could process food like our cells do: let it in through a membrane; close the membrane behind it; absorb it; and expel through the membrane. | |

| Aug 25, 2021 at 9:46 | comment | added | Ben McKay | Creatures made of molecules in any number of dimensions are highly disconnected. (I am not sure if that is what Pietro Majer meant in his comment.) | |
| Aug 25, 2021 at 8:57 | comment | added | Pietro Majer | but what is the problem with being disconnected? many of us are, in a sense | |
