Haha, notes are so disturbed to learn that pearls form inside the tissues and not just lying inside.
So how do y’all feel about the fact that pearls have nothing to do with sand? Bivalves deal with sand all day long, of course grains don’t get “stuck” until they have to make a pearl. That was the assumption centuries ago and just continues to be spread by the jewelry industry as a plain old lie.
The formation of a pearl is to smother and permanently seal the parasites bivalves contract from all the animal feces they process :)
