Here are some barnacles
I took these photos of barnacles! Enjoy!
I know that the top is probably actually a California Mussel but I have no idea what the bottom is. Apparently it's some kind of Goose Barnacle.
For some reason I mentally classify everything attached to a boat as a "barnacle," but I know this is not actually the case. I've read a bit about barnacles today to educate myself but am not yet wise enough to report back. So you can just enjoy these pictures!!
