Greetings CONCH-L,
I have a rather simple (possibly dumb) question
regarding the Operculum of Gastropods. When a book refers to an Operculum as
being "horny" what exactly does this mean? I assume it means that the makeup
of the Operculum is the same as a horn or antler because I've never seen any
horn, spike, or protrusion on them before even under a microscope. I'm I even
close? Thanks in advance.
