Anatomy
These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch" which can serve perfectly well as a gill when they are unable to reach the surface for air.

gollark: The network effects thing also doesn't apply to, say, use of other random cloud services. Unless you are also synchronizing your contacts and other data vaguely related to other people to those.
gollark: I suppose you could say that about clothes and things too, but it's not exactly *as* necessary.
gollark: If you buy, say, some sort of food, your friends don't have to buy that if they want to interact with you.
gollark: And most non-messaging/social media stuff isn't subject to the same network effects.
gollark: I mean, not *really*, people will often say "well, if you buy [PRODUCT] from [COMPANY WHICH DOES [BAD THINGS]], you're supporting [BAD THINGS] to some extent".
