Blue teeth

This I haven't seen before: on the rim of a shell of a mud snail in my aquarium, there are tiny, bright blue dots.

Batillaria attramentaria, about 1/2 inch long.

A description on the WallaWalla.edu site mentions that the lip of the shell has teeth inside it. Would these be the teeth?

  1. Just saw some mud snail shells on a blogging friend's Instagram post. She's visiting family on Vancouver Island right now. - Margy

If your comment is on a post older than a week, it will be held for moderation. Sorry about that, but spammers seem to love old posts!

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
