We've got an African Giant Snail a few years ago but failed to identify the exact species so far. When we got it, it's been about 20 % smaller than now, so it's probably not been an adult snail, but we don't know the exact age.
We only got this single snail, so there's no way to check for the eggs.
Here's a picture (small version, about 400 KiB) and a link to a bigger version. If you need more detailed pictures of certain parts, please let me know.

This picture shows that the apex is about 12 centimeters (4.7") in length, while the foot is about 14 centimeters (5.5").
