Star Trek

I've been watching all episodes on Netflix. 2 or 3 episodes a night. Is it me or is this the first episode (S06e02) where I seen new Species roaming around the ship using terminals in the back ground? time frame 26m40s - 26m49s?

They needed bunch of aliens to fill the background, and they figured we wouldn't notice. Why they'd figure that I can't imagine since Trek fans seem to have near photographic memories for things like this.

Yeah I also noticed this, there is also an alien in Engineering resembling one from the banquet scene in Insurrection; Troi commented on the beaded piece they placed on Captain Picard's head, forget their name.
