discover a study about oysters

They will lay there when the sun is up and the tide is down, usually two times every day. In between, when the tide rolls in, they burrow down into the sand and wait for another chance to climb back up and sunbathe again.

If you're a Convoluta removed from your native beach ... you're a French beach worm, born, say, on the shores of Brittany, and some aquarium owner moves you to, oh, Istanbul — a year later, will you switch and start keeping Turkish time or will you stay loyal to France? Whose tides will rise and fall in your little brain?

Dreaming Beachy Dreams Now comes the really cool part. In his , Caspar Henderson writes that if you take these worms home to your aquarium, they still act as if they're on the beach. Twice a day, no matter how far you are from any ocean, they will wriggle up in their new sandboxes and try to sun themselves.

I looked around for answers, and while I found nothing for Convoluta, I did discover a study about oysters, oysters yanked from Connecticut and plopped into aquariums in Chicago. Writer Barbara Kingsolver mentions it . As she says, "one story takes the cake."

In her book The Sea Around Us, Rachel Carson admired this about Convoluta: "Without a brain, or what we would call a memory, or even any very clear perception, Convoluta continues to live out its life in this alien place, remembering, in every fiber patch cord of its small green body, the tidal rhythm of the distant sea."
