Definitely!

Yes, that's one of the nicer part of Project Noah, learning about the Organism and not just looking at nice pictures :D

Very cool. They are much more interesting than I ever thought. Being territorial is certainly unexpected too

Thanks to you, @Machi for directing me to look up further to learn more about Limpets :)

Here is the article about the research on them. Do check out the video too in the article :

Wow, that is amazing! I never would have thought that a mollusk would have teeth, especially not teeth that are the strongest biological material ever tested

Its definitely a limpet. The conical shell is very distinctive, and Chiton have plates down their backs. Thank you for the suggestion though, Albert! I am always in admiration of your collection

I think this are Chiton
