What stops us from having both?
If I remember correctly the game will throw a hissy fit and prevent us from doing so, but I could honestly be wrong. It's been a while since I've played, and I obviously didn't try mixing mouths that often.
I've done it a lot before. It's okay.
And do we just want to chat about diet?
We should probably have a chat about diet. After all, it'll be a large influence on the later stages of the game.
EDIT: Well, a influence at least.
True enough. And if we go with the both-mouths idea, we don't have enough DNA for a spike.

Here are our options:
1. We have a creature with a filter-feeding mouth and a spike.
2. We have a creature with jaws and a spike.
3. We have a creature with a filter-feeding mouth and jaws.
Which should we choose, where should we put our spike (if any), and what shall we name the creature?
