Sea Pearl


This is a photo of what I have been told is a sea pearl.  I was further told it is an alga.  It looks like a silver egg.  The photo was taken in St. Lucia.

I couldn't find any confirmation or information on line or in Reef Creature Identification.  Is it an alga?  Is it a sea pearl?  Is there a source to learn more about it?

Thank You,


Sea pearl

Perfect.  Thank you.  This forum is so educational.  I love it, and I am deeply grateful for your help.
