    Is this a pond snail?

    Focus Please

    Hi,

    Based on the photos it would be a wild guess. :rolleyes:

    Focus please. Pull it out of the tank and photograph on a light colored background lay a ruler preferably millimeter scale next to it. :gw

    If you can give the number of whorls right or left handed.

    Is This Any Better?

    I can't find it now to pull it out, but here's another picture I took with the others. It's maybe the size of a pencil eraser.

    Nat Geo Has Openings

    Hi,

    My first reaction was some sort of New Zealand Mud snail, perhaps Physidae sp. :p


    Looking at this again, I suppose it could be a spiked Apple snail variant, Pomacea bridgesi, sometimes called P. diffusa. :rolleyes:


    However based on what I see and assuming the subject is an adult, my final answer (for now) is Tadpole or Pouch snail, Physa sp. :)



    • Small.
    • I base this on that appears to be left-handed (guru types would say sinistral).
    • I see no gills, if there are gills it ain’t. (Guru types would say, it is an air-breathing critter with lungs.)
    • The pointy part (guru types would say spire).
    • I see no little lid (guru types would say operculum).
    • Appears to be a long opening (guru types would say long aperture).

    Pouch snails are generally good guys. :gw


    Snail identification is difficult and without clear photos with size references, it is hard to tell.

    Looks like a Radix (Lymnea) species due to the the triangular shaped antennae. They are easily distinguished from physa in that they have string-like antennae. Unfortunately I am unsure of the exact species of radix (Lymnea). I would guess it could be Lymnea (radix) ovata or Lymnea (radix) auricularia. Please see reference to Limnaeidae in this article.

    Best Regards,

    Stuart

    Clear Photos

    I think this is as good as it gets. I noticed during my water changes today it tended to try to stay at the water line, if that helps.

    I Will Stick For Now

    Hi,

    I will stick with my Pouch snail, Physa sp. for the reasons listed above, I think I know the species, I will, see if I can confirm.

    Snails can be tricky. :)

    It is a good snail. :cool:

    Lymnaea columella

    They're air-breathers.

    Good Catch

    Hi Stuart,

    Good catch on the antenna, I missed it completely, even after you pointed it out. :eek:

    Pouch snails, Physa sp. are also air breathers. :)

    Lymnaea columella? Cool. Whatever they are, they get absolutely HUGE compared to the other snails.

    You're welcome. I only know about the antennae trick from an English version of a German invert forum. These are good snails that don't eat healthy plants :)!

    Best Regards,
