Yes, @Gaiai80.
You would need to dig them up or break up the coral substrate to get them, if you want to.

Thank you, @ornithoptera80 :)

Thanks, @Gaia80 for your kind words and appreciation.
This Crocea Clam is also known as Boring Clam, in the sense that they are bored/digged into substrate, usually hard coral blocks and remains there permanently for the rest of their life.

Thanks @remkinlock for your kind words and for sharing your experiences with them :)
