Deep throat

I scrubbed the glass aquarium wall, but left a few faint spots of algae. A mud snail, looking for a meal, had to open wide to scrape off the leftovers.

Mud snail, Batillaria attramentaria, and copepods.

Looking closely, down his throat, a few ridges are visible. As far as I can tell, this is the radula, the file-like ribbon that peels his food off the surfaces where it grows.

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!
