The flying birds are hexapods as well, 2 sets of wings + legs. And most breath through the side of their necks, like gills.seanthesheep said:Mainly as a plot device, but logically it would be a good idea to have a bayonet because if the enemy creature (Na'vi or otherwise) gets very close, or the fight goes on until they run out of ammo, a knife on the end of your gun is more fun and less risky than punching them.DukeisClay said:-snip-
Now a question of my own that's not quite a plot hole either. Why do the mech things need knives?
Fridge logic of my own: Why do all of the land creatures (I'm not sure about the flying creatures) have six limbs, and most have a tail, while the Na'vi only have four?
The reason the Na'Vi are humanoid are because people would get freaked out and not be able to emotionally connect to something too alien. You can test this: Open up Spore Creature Creator and muck around creating some monstrosity. As soon as you give it a face you can read it's emotions, until then, nothing.
I kinda wish Cameron had the balls to make them non-humanoid. Heck, a extra pair of arms would suffice, and neck-noses wouldn't look too alien.
