At a loss

[specialist]

I didn't know where to put this so here goes.

I know that this is a custard apple, but am unable to identify it and if it is edible? Any help would be appreciated.

Looks like a soursop (http://en.wikipedia.org/wiki/Soursop), aka thorny custard apple. Edible, for sure.

I'll second that. Soursop for sure.

My parents have a tree at their house. It's a bit of an acquired taste for some.

Thanks for that, I was almost sure that it was, but after wading through 45 pages of images from google confusion set in.
