There is so much happening in the field of deep-sea coral research right now that there is no way to cover everything in detail without cheating you out of some of the excitement, so I’ll list it all in a couple posts and let you pick through it over the holidays. This assumes you’re interested, of course.
I really hope you are interested, because Craig tells me he’s going away for a week over Christmas, leaving me to “let it snow, let it snow,” so as far as I am concerned, it’s Instant Anthozoa here at DSN. If that makes you uneasy, Craig has a few ghost-posts in store, so please don’t flee.
I’ll post some of my old favorites and try to finish up a series of posts called “5 ways deep corals are like shallow corals.” The series started waaay back in early 2006, and it’s about time to bring that little project to a flourish.
The quote of the week for deep-sea coral research goes to Dr. Lance Morgan of Marine Conservation Biology Institute.
“Few people, even marine scientists, know that the majority of coral species live in the deeper, colder, and darker depths of the ocean…”
That’s it in a nutshell, folks. If you love corals, you should love them all. Love them all the way to the bottom of the sea, where they are out of sight, and too long out of mind.
By the numbers:
