Help to identify silver ball

Help!

I was in Curacao and saw these silver balls in various locations. No idea what they are.

In this image you can see one under the Puffer

Anyone know what it is?

Thanks,

Mark

It is a type of Green Algae called Valonia ventricosa or 'Sea Pearl' for common name.

I think it is the largest single cell organism.

Another commonly used name for this algae is sailors eyeball.

Also known in the aquarium trade simply as "bubble algae". It's quite "undesirable", although I've never quite understood why.
