them in the cutscenes then? - those that appear to possess humans.
Well, like I said in edited post, they are part of the collective, these seen in cutscene are infiltrators. Ships are different, but Nomads too. If you notice they all share distinctive features like "three wings/leafs/etc" each rotated by 120 degree, even their own portal have three wings, nomad lair have three antennas, and they seem to be fond of rotational symmetry.
That ship in extended intro is certainly not a battleship. It looks different if you pay attention. It has split wings on the back instead of regular ones (and nomad battleship doesn't have wings, it has three points in front instead), a lot more "bones" inside and far larger than any ship. Possibly a unique ship, but then again, may be not.
So, there you have it. A space plant. That's what some may think, but that's not true. These "space plants" managed to bring down human colonies in Sirius just by infiltration, that implies they are far more complex than that, and that's what makes them interesting.
