This is the only Strawberry conch shell I have and I’ve been trying to find out about it for a while now.
They can be all white outside or with marking like mine in these photos, but they all have a dark orange, red or pink inner lining with a dark brown or black border at the opening.
It is shaped a lot like a cone shell, but I don’t believe it is called a cone. I’m not sure.
Conch is the name given to a wide range of medium and large size sea snails in the Strombidae family.
