I can't help you with all of the info, but I can definitely correct about Achatina iredalei.
Average shell length is only about 8-9 cm. They don't lay any eggs, they give birth to live babies. Average number of babies are said to be about 10-20, but I've had litters up to 37 babies. I keep mine at room temperature and in about 70-80% humidity.
Good luck with your site!

There's a few error's in the guide section of the site aside from the iredalei information. Also, Achatina craveni are from South Africa, they're average length is around 3-5cm. Megalobulimus can be found in the Caribbean, Brazil and other parts of South America, they arent found in Spain though, or anywhere in Europe. Most of the captive ones are from Uruguay, and are subspecies haemastomus. Archachatina degneri are from Ghana. zanzibarica and iredalei are from Tanzania, immaculata are from southern parts of Africa, including Madagascar. Achatina glutinosa are from Mozambique, most pictures I've seen of them in captivity may be actually fulica, though I am not sure.
Would you consider adding cepaea hortensis and cepaea nemoralis and Oxychilus alliarus to your land snail guide? Those are the types of snails I have and I would like to see pictures and information as well as post Pictures and information on your Land Snail Guide. My cepaea's are mainly six banded (one three banded white I recently noticed) and I have Yellow, Rose and White. Add in: I've noticed the website attached to this particular forum includes information for other species as does this forum.
Lovely-looking site loving the pictures and the layout, the style and the categories of information.. Hope you don't mind a few comments.
Is the rarity guide referring to how often the are found in captivity or in the wild? May be worth updating the Megalobulimus to 'endangered in some habitats' With Cepaea I would say very common. Achatina achatina (Tiger) they are declining in numbers mainly due to the food trade, and perhaps up the temperature to around 28 degrees C.
Do you mind me commenting on this? "However, GALS are native in African and America in most cases if you want them". The Achatina fulica can be found in parts of America but only because the were introduced. They are not a native species to America and it is infact illegal to keep them over there
