Name that CritterSeen an interesting wee beastie or giant sea monster but don't know what it is? Describe it here (or post a photo) and let the vast experience on ScubaBoard help.
That's the bubble coral Plerogyra sinuosa. It looks quite different when the polyps are retracted. If you had examined it closely you would have found some beautiful shrimp, crabs, & worms that live with it.
it actually is a stony coral in the broad group known as large polyp stony corals (LPS). It does have an abundance of soft tissue but it grows from a CaCO3 skeleton
So many worms, so little time!
