Heyyyy mollusk fan here :)

Can I have a snail assigned?

Also what pet snails would you recommend? Going to be kinda off grid in the future, so land snails seem best, but I'll be in a pretty temperate PNW climate.

Thx 😊

You most certainly can! You get a...

On pet snails...

I mainly keep C. nemoralis. I've also kept a M. fidelis at one point, though sadly it died a few months after I caught it - I'm uncertain if this was due to natural causes (i.e. old age) outside of my control, or if it needed a different type of care than what I was providing for my C. nemoralis. I've also kept a variety of tiny glass snails (Oxychilus sp.), though in those species it's much harder to distinguish between individuals, so I'm uncertain how long they've usually lived in my care.

I can vouch for C. nemoralis as being quite straightforward to care for! I haven't had C. aspersum before but I imagine they're similar in terms of their needs. Both come with the additional bonus of being invasive in the PNW, so if you find one in the wild, I wouldn't feel guilty about taking it home as a pet! Just make sure not to re-release them, and especially don't try to rewild any hatchlings or eggs you may wind up with. Their commonality also means that you can buy them online from breeders.

Again, I can't provide a lot of advice for keeping Monadenia species, since I've had limited experience. I do have an acquaintance who's been keeping one for at least a year in conjunction with a C. nemoralis though, so I'd expect their needs to be pretty similar (though Monadenia might need a bit more room, given they're larger). Monadenia are native to the PNW and too uncommon as pets for there to be breeders (that I know of), so if you want some you'll have to find them yourself.

TLDR: I'd recommend Cepaea or Cornu! They're common, easy to care for, and you can collect them guilt-free. If you're interested in something bigger and/or less well-documented (in terms of online resources about keeping that species specifically), such as Monadenia, I'd advise learning the ropes of snail care with the aforementioned species first, just to make sure you've gotten some experience under your belt.

Of the snailblr blogs I'm aware of, I know @northengarden is quite experienced with keeping and breeding C. nemoralis, so it might be worth asking them for thoughts/advice.

If anybody else has experience with keeping snails and would like to chip in with their own suggestions or advice, please feel free! I am by no means an authority on the subject - this is just what I've gathered in the year and a half or so since I started keeping snails.

Convergent evolution of Amphidromus-like colourful arboreal snails and phylogenetic relationship of East Asian camaenids, with description of a new Aegistohadra species

ABSTRACT

East Asian terrestrial snails of the family Camaenidae are diverse in terms of genus and species numbers, shell morphology and mode of living. This family also includes colourful conical arboreal snails that traditionally have been assigned to the genus Amphidromus. Yet, the present study shows that, despite their deceiving conchological similarity, some of these East Asian arboreal snails do not belong to the genus Amphidromus or the subfamily Camaeninae. The presence of a dart complex comprising a mucous gland, a dart sac, an accessory sac and a proximal accessory sac, along with a pronounced penial caecum and molecular phylogenetic analyses revealed that former ‘Amphidromus’ dautzenbergi, ‘A.’ roemeri and ‘Camaena’ mirifica, and one additional new species belong to Aegistohadra (subfamily Bradybaeninae).  Aegistohadra dautzenbergi, comb. nov. and Aegistohadra roemeri, comb. nov. are conical with colourful spiral bands, whereas Aegistohadra mirifica, comb. nov. and Aegistohadra zhangdanae, sp. nov. are heliciform to conical with colourful, variegated spiral and transverse banding patterns. DNA sequence analyses also revealed that each variety of Aegistohadra dautzenbergi could not be differentiated by mitochondrial (cytochrome c oxidase subunit I and 16S rRNA) gene fragments. The phylogenetic position of Aegistohadra within the East Asian camaenids revealed that the similar appearance in shell morphology, microhabitat use and diet to arboreal snails in the genus Amphidromus is homoplastic. Moreover, the presence or absence of a dart complex is also homoplastic and is unsuitable for suprageneric classification. By contrast, the presence of a flagellum and a penial caecum is useful for the suprageneric classification.
