ID Please

Hello

Just looking for an id on what I believe is a sponge on the side of my clam

Thanks

Yep, harmless sponge but I'd remove it from the clam shell as it can spread fast

+1, a soft toothbrush will work just fine.

I figured as much just wanted to double check..Its gone from the size of a penny to a silver dollar size in the last 3 months
