They could be nomadic because of normal R.Ludroth in the area with harems may force them out of the area because they different (monster hunter racial bullying :( poor P.Luddy). Like I said about them being paler could be because they're albino. The reason they may not swim is the poison might leak out and either clog up with the water making a goo? I'm not sure on the not-swimming part though.
