ENV: Not-Really-a-Cat-Friday

Seven-whorled Toothsnail, Polygyra septemvolva volvoxis




Crawling on the windowsill this morning was a small snail that is often confused taxonomoically. Ours is identified as the Seven-whorled Toothsnail, Polygyra septemvolva volvoxis, but it seems to be confused throughout its range with Polygyra cereolus. I have specimens of that beast from Florida -- at least they came IDed as that from someone i trust -- and that critter, while superficially similar is T-Rex compared to this guys' lizard. The one in this photo is barely a quarter-inch in diameter, while my P. cereolus specimens are nearly an inch. The volume difference is considerable. Aydin Orstan at Snail's Tales has a similar post -- he's not sure either. For now, at least, i'm continuing to label mine P. s. volvoxis.

As always be sure to check out The Friday Ark at The Modulator for all the other critter postings since last week.
