Cipangopaludina japonica River Snail

 This is not a fossil but it could be one day.  Snail shells found in the White River of  Indianapolis, Indiana.  Some how this Asian snail has gotten loose in the river and is multiplying.  I found 6 shells on a 5 meter stretch of river bank.  A naturalist at the Indiana State Museum identified it as maybe a Cipangopaludina japonica.

Two specimens are shown in these images.  The largest is 5.2 cm long, 4.0 cm wide, and 3.8 cm tall.  I wonder if these creatures are edible?

In addition, I found two types of river bivalves and two other types of smaller snails.

Hello. I am writing to try to get in touch with the person that posted the photos. I am trying to obtain permission to use a photo of Cipangopaludina japonica for an invasive species database, as this species is invasive to the Great Lakes basin. If anyone know how/who to reach out to I would appreciate them letting me know. Thanks. -Susie

You can use the photos for your database. My e-mail is louisvillefossils@gmail.com if you want to contact me directly. Also there are more photos here including what the shell looks like after it has been cleaned: http://louisvillefossils.blogspot.com/2011/04/cipangopaludina-japonica-river-snail.html
Note, the species name might not be correct apparently there is one from China as well so this might be that species.

I found several empty shells at the White River Canoe dock. Some were large & embedded in the surrounding soil. Looked around & saw several more…all sizes! Fascinating!!
