O believe it to be A. fulica, although A. achatina would be ever so much more cool. $10 got me this one...lots of breeders up here, and although I never bothered having any before, I liked this one and the price was right.
You can't have any Achatina ssp. in the US, anyways....the department of Agriculture down there prohibits them nation-wide....a few actually made it into some school classrooms about 2 years ago, and the Ag guys actually burst into classrooms during classes and seized the snails....of course, if you hang out on any online snail groups, you will know that there are a fair few being kept privately down there.
