We used to grow clams, we bought the seed when they were the size of beach sand and grew them to sellable size. There are many weird creatures in the deep ocean, they say only 20% of the world's oceans have been explored. I was wrong I googled how much has been explored, and it is 5%

I find making buttons from clam shells very interesting.
They must not make them anymore because we threw away hundreds of thousands of clam shells.
