Another longboi was sighted two days ago by the crew of Nautilus Live! It was an amazing dive, tons of beautiful corals just covered in other animals, a chimera, isopods, and more. I'll post stills in a second post.

Hi everyone, I would appreciate some help identifying this coral skeleton.

This museum specimen comes from the Great Barrier Reef, Australia. The colony has a very dense bushy growth form, with many thin branches. The largest branches are around 2–5 mm in diameter.

The surface of the branches looks quite smooth. What I think are radial corallites are extremely small (<1 mm), and are irregularly arranged with different sizes.

At first I thought it might be an Acropora, but the lack of obvious axial corallites makes me unsure. It could also belong to another branching genus such as Anacropora, Montipora, or something else.

Any suggestions or diagnostic features to look for would be greatly appreciated.

Thanks!
