Is this a cherimoya?

[spaugh]

I bought this from the farmers market today.  Its 2lbs and cost 10$ so Im hoping its good.  The guy who sold it to me said it was a guavana or guabana but he had a strong mexican accect so I couldnt tell if he was saying its a cherimoya or its a close relative.  Any ideas what it is?  Would it be worth saving seeds?  Can the seeds be dried out and saved or do they need to be grown right away?

Looks like a Cherimoya, the type with spines 
I am not an expert, so , I am sure someone will chime in who is more qualified to give a correct answer

Spaugh,
The seller probably called it guanabana...looks like an atemoya or cherimoya.

It's probably not worth saving the seeds unless you want to grow rootstocks.  They can be dried for later planting.
Better to buy grafted trees if you can figure out the variety you like.
Cherimoya and atemoya scions can be grafted onto either cherimoya or atemoya rootstocks.

It tasted like pure sugar.  Was a little fiberous, maye needed 1 more day to soften up but it was extremely sweet.
