Question on attacks of opportunity

[Kaerou]

Hi guys

Simple question: If I have a natural attack (bite in this case) and a 10ft weapon (spear) do i threaten attacks of opportunity on both 5ft and 10ft squares? Or do i have to choose which weapon threatens AoO's at the end of my turn?

You threaten with both at all times, so you'd have every space within 10ft covered. For those without natural attacks, armor spikes are commonly used to threaten those spaces (or Spiked Chain just does it all, but that's another story).
