Chitons

Check out these Chitons. I didn't know what these were either, until I posted the photos to an aquarium message board. These critters are supposedly harmless, and graze on algae. However, they have multiplied quickly, so I may need to do a bit of "cleansing". I'm also paranoid that they will one day crawl out of the tank, crawl into my ear and latch onto my brain stem. You can understand my fear when you see these prehistoric badboys upfront. Check out this research publication with different species of Chitons. Definitely gives me the heebie jeebies... *Brrrrrr*

If you've had any experience with Chitons, let me know...
