We saw the raclaw in the first offcial trailer so i surspect we can. If we can then there would be somthing like an animal training building or unit that tames the creature/s on the planet. Did you mean rancor by any chance? Anyway I don't think that that is a part of this game. The indigenous life will be there. Low intelligence animals will probably attack both sides (rancors) or would just be peaceable (banthas, tauntauns). The more intelligent species, from the FAQ that Rogue made on the LEC forums, will be able to be "wooed" to a side or maybe even lend aid to both sides. I took that to mean new alien units available to your side, but I'm not sure that that is exactly correct.
