mollusk enjoyers!!!

hello everybody, i plan on doing a mollusk of the week every week on my blog, so i'm interested to know if anybody has any mollusks that they really love! i myself am new to this interest and i am always looking for new mollusks to research and appreciate (nudibranchs and cephalopods pique my interest in particular :3)

you can include images, facts, whatever you'd like! i hope to see some cool creatures :)
