An Open and Shut Mystery
This sea creature has a soft body and wears a shell. The part of the creature you see helps to protect the soft parts of the animal. It also helps the animal avoid drying out if the tide goes out, leaving it out of water for awhile. To what creature does this belong? What is this part?

Maybe this photo will help. While Ron was visiting, he borrowed a larger shell from Mrs. Taylor's class to show us how the little piece works.

It is a door to a shell.

The animal is a cone snail.

We think that the door protects the snail from drying out when the tide goes out.

Regan and Taylor have this perfectly. The door of the snail, its operculum, helps to keep all the snail's moisture inside. When the tide goes out, the snail has to wait for the water to cover it. Today, at the beach near my house, the sun is shining and snails have to be out in the hot sun for about two hours before the tide rolls back over their bodies. The door is closed all the while.

Thank you for sharing
I think this is a really good thing to have for elementary students.
