They are legal in the states - but you'll need to check your state and local laws. I beleive the smaller southern form (sebae natalensis) MIGHT be protected in parts of southern Africa. The much larger sebae sebae is not.

They can get huge - and they have been known to have iffy dispositions.

How big is it? How long have you had it and where did it come from? Under no circumstances will that be a one-person job when it gets bigger. I have a female around 9' - she gets nervous on being held but otherwise is fairly calm for an AfRock. I would not consider her docile or laid back by any means though.
