Creature

"Creature" refers to a member of your species, which you control from the Creature Phase to the Space Phase. This article refers to the Creature Phase only. You control your creature in a third person view (the mouse seems to be used in the video), giving it simple commands that can be combined. For example, you can WALK or SWIM to a spot, then ATTACK a smaller creature. Once it's dead, you can begin to EAT the corpse, but if you WALK or SWIM away from it at the same time, your creature will drag (this isn't a command, rather an effect that comes from combining two) the corpse with it. Primitive creatures can lay eggs like the cell can, but it is also possible to mate. There may be benefits for this beyond being able to evolve "at will". Instead of the Microbe Editor, creatures are evolved in the Creature Editor, which is far more powerful than the Microbe Editor. Once you have evolved your creature to what you want it to be, you can upgrade your creature's brain to the final level and go to the Tribal Phase, where you control a Tribe.

=Genetics=

Each creature will have its own set of genetics, which is (in practical terms) the procedural code compressed to small size which generates the 3D creature on a player's machine. It is unclear whether a creature's genetics can be manipulated purely through editing the genetics code, rather than through the Creature Editor. Which would be comparable to editing the data file for the character instead of the editor.

Creature Size
Creature sizes are able to be adjusted by the player. Will Wright has previously suggested that the largest size will be elephant size and the smallest will be hamster size.

Aquatic
For the challenges that may be presented by aquatic civilization, see Underwater Civilization.

Flying
Although confirmed by Will Wright in the Gaming Steve interview, the mechanics of flight in the game is not yet known. A flying species can't build flying cities.

According to Gamespot it was seemingly impossible to create a flying creature during the E3 playable demo of the Create a Creature system.

There have been no flying creatures present in any of the demonstrations or sample creatures. There has been no reference to flying creatires since the 2005 interview, so it is possible that flying creatures may not make it into the game, or at least not in the initial release.
