What is that

So my diamond goby unearthed this... I have no idea what it is. I have not moved these rock in a long time. Anyone?

Could it be some kind of thin shell? The texture is sort of hard to tell

So Bruce (the goby) covered it back up. I guess I will see what tomorrow brings. He does pretty well for a guy with one eye!!!

Possibly some type of sponge?

It could be something decaying beneath the sand. I've seen those sorts of "growths" on piles of uneaten feed before. It's typical to see a hole or two on the top in those situations.

Did it move at all? If it’s slinks away, it could be some sort of flatworm. If you get a chance again, scoop it out. If it is a flatworm, it could eat your snails.
