I see planty of stuff - it is just hard to see because of size and color. The underlying hard corals aren't doing very well here, but there are many octocorals and small sponges and hydroids, plus the stuff feeding on them. [17:36:07] So, this isn't as dynamic as the Lophelia mounds on the east coast of Florida, but it is far from barren. I've seen barren on Pacific seamounts, and this ain't it! :-) [17:36:57] Lobate ctenophore, I think. [17:38:52] I'm going to take this blue water opportunity to re-locate.
