Seashell

A helmet shell in the genus Cassis. Either Cassis cornuta or Cassis tuberosa.

Hi! Can you write where your friend found it in the Habitat box? That will help our experts to give you an ID. Do you know if he found it alive or just the shell?

Thanks. Α friend found it in indonesia and gave it to me. I uploaded it here in the hope that someone will know what it is.

I have corrected the spelling of Seashell. I hope you do not mind. Where did you find it? It is large...and pretty.
