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

Thanks for the insight Albert, a strategy for being safe I assume. One have to be able to chew away coral to get to any of these :)
AlbertKang
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.

Wow, what color-pattern! Your underwater photos are amazing. Are the clams intergrated in some sort of coral? Or is it part of some kind of structure created by them?

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

Beautiful photo Albert. First saw these iridescent colours in the giant clams in Niue and then my daughter and I researched the symbiotic nutrition-providing microalgae creating these colours. An amazing relationship! Thanks for sharing.
