| Feb 8, 2018 at 4:51 | comment | added | Tardigreat | I think the only way that one is realistic though is if it evolved from a multi-headed animal and just retrofitted one of the heads for just one function, or you could propose something like Snaiad's aliens where the two 'heads' are really mostly an illusion; one head is actually the creature's genitals, it just has a jaw like protective covering over it that it retrofitted for biting. Very weird description if you don't know what I'm talking about lol | |
| Feb 8, 2018 at 4:47 | comment | added | Tardigreat | @wetcircuit that's fair! If you really want to separate function in a curious, but very alien way, you could have a two headed creature that uses one head purely or mostly for sensory input (vision and hearing would be most effective), and the other head only have the purpose of attacking and rending food. You could have the sensory head be hypermobile, like a tentacle or owl neck for nearly 360 degree feedback. Funnily enough, I think this sensory head would require more brain power than the other, so one could consider it the 'main head'. | |

| Feb 8, 2018 at 4:34 | comment | added | Tardigreat | @wetcircuit You don't need to have more heads to have more mouths. A starfish has no definable head, neither does a clam, yet they have mouths. If I just said 'more heads', I wouldn't be answering the question. | |
