Sponge, the black dots are actually holes , or siphons for the intake and outflow of water.

There are many types of calcareous sponges. These [acronym:a3cde25dc0="Calcium carbonate"]CaCO3[/acronym:a3cde25dc0] formations can often look just like many types of encrusting corals rather than the sponges they are. Ever noticed those "jelly" looking formations laced together on the underside of [acronym:a3cde25dc0="Live rock"]LR[/acronym:a3cde25dc0] or in darker areas of the tank? Those are another form as well.
