Giant African Land Snail

I’ve read that it has pretty much spread to all provinces of Thailand. It is considered an edible snail 😰 so one has to wonder if snail farming/cultivation has anything to do with its naturalization. And yes, once the duck gets to it, it’s game over for the snail! I like to remind people not to handle these snails because they tend to host a nematode that leads to a life threatening parasitic infection of the nervous system (rat lungworm disease).

Your ID is correct. Check out this article: http://www.columbia.edu/itc/cerc/danoff-burg/invasion_bio/inv_spp_summ/Achatina_fulica.htm
