What am I doing wrong?

[voyager156]

I have snails Pleurodonte marginella.

Lately, I noticed that one of my adult snail shell looks strange. Like one "segment" is protruding. Also one of my young snails has the same problem.

What am I doing wrong? I'm worried about them :-(

Hi voyager156,
don't worry....... . That happens sometimes in Caracolus marginellus(a). I had three of them with the same feature and they all lived fine and healthy.
Kind regards: wolf

Here are photos of the aforementioned poor little guy. The white stuff on his shell is calcium powder.

I never kept these snails and I try to believe wolf when he says there is no need to worry.
To me the shell looks a little bit like it is disintegrating and falling apart...
Is this normal for Caracolus?

Hi all,

it’s a little bit difficult for me to imagine that the whorls really are „detaching“ after being built. I think it is more likely some mild „irritation“ in growth direction, a little bit like a trend towards a scalarid growth. The picture shows one of my Caracolus marginella with this feature between the penultimate and the ultimate whorl (living fine for several years).

Perhaps the specimens of voyager156 additionally (!) have a little problem with calcification of the whorls and lost of periostracum (which isn’t so much important).

Kind regards: wolf

Hi again,

another freak specimen of Caracolus marginella. No problems over years. Normal growth in penultimate and ultimate whorl.

At all times the whorls were very tightly connected and solid. No free mobility at all. A transient slight tendency to scalarid growth.

Yeah it looks like its probably pretty normal for the species
