" hi, my name is jo. i don't know anything about mollusc or gastropods, but recently i was reading an archaeology article from a site in pr and they include a long list of m & g. I realize that some of those were lands species, but they never explain which ones nor which of all the species mentioned were edible.

i'd been looking through your site and i don't see to find the species that i believe are terrestial. can you check the list for me and confirm that they are terrestial and if possible to tell me if they are edible?"


hi avril

thanks for the links, i'll try them during the weekend. however, any other information that you get i'll truly apprecciated. if you can't find references about then being consume, at least let me know if any of them can be discarded as a food source due to foul taste, for being poisonous or any other reason.

  • Of course you also have to wonder about the edibility or toxicity to humans of their stomach contents...any insecticides etc...just a thought. I don't think I would trust eating most land snails that were found near human habitation (same rules apply to marine ones). ...Peter

  • I don't have the reference immediately at hand but remember encountering an extensive list of Cuban potentially edible mollusks.

    For the land snails, one might have a guess based on their size and abundance as to whether they would be worth trying to eat. Also check for any evidence of hemit crabs, which might be eaten.

I don't know of reported toxicity of land snails, though some slugs are known to have chemical defenses, and some snails have been suspected of toxicity because of being conspicuous.

Some of the shells in an archaeological context might have been gathered for ornamental purposes. For land snails, there's always the possibiity that they just crawled there-a shell midden would be a nice source of calcium. ...Dr. David C
