Chitons

These (Polyplacophora) are actually not snails or slugs (Gastropoda), but they are related.

Here is mine, perhaps about 2 inches / 5 cm:

Under is the foot and the head with the mouth.

This and my abalone I bought in saltwater aquarium stores, but otherwise in different places. I did find a Chiton on the Swedish west coast, but I didn't bring it home. It was green with a pattern of lighter and I guess darker areas and pretty small.


Here are more pictures:

In the last picture you can probably see a gill above the foot.

I haven't seen any eyes yet, I don't know if they have any :-) Chitons have 8 shells. I've read that they can scrape marks in plexi glass and that they stick really hard to things. In the store it was removed from glass with a razor.

Do you mean all the skin with the lines around the white foot are it's gills? Wow! He is really something! There are so many bizarre and amazing creatures found in the ocean--I don't think we've even made a dent in learning about all the fish and animals down there :o

No, just between the foot and the "skirt" where there is something with ripples. It sometimes pulsates with them up and down.

Another interesting thing is that the area where it rests turns whitish where it has its foot, as if it was depositing calcium.

The foot moves with simple front to back ripples. It can move pretty fast (not as the abalone though I guess) and looks like a little ghost sliding around :-) Most of the time it moves slowly though.

And the foot looks pink in a funny way, almost like skin. I wonder why it's pink.

I read the link that you posted and there was a picture of a person holding a very large chiton. Is yours that big? :o His skin looked orangey--kinda like a mango. They must be gentle animals to be able to hold such a large one without being bitten. It was a very interesting article too, thanks so much for posting it! And of course I read about the gills AFTER I asked you the question. Maybe I should read the article first next time :oops:

No, it's not that big, perhaps about 2 inches / 5 cm. Yes they are gentle, if you get them loose some at least do like mine did, roll into a ball.
No problem, I don't expect people to read the article, and all questions are welcome!

It has now found itself a home in the lower right corner of the front glass where it parks every day. It seems it is still increasing activity since I brought it home.
