From a distance I thought reef squid, but when the footage got closer, I see not a bilateral set of fins, but a single dorsal fin undulating for propulsion. The end has what looks like an Elph shoe curl, lol.

This one has me stumped.

Opening shot is a Hawks Bill turtle trying ti sleep under the edge of the coral! Is that what we are talking about? Come on where are your sea eyes?

NO, I think he is asking about the critter he filmed after the turtle.

I don't know exactly what that is, but it looks to be some form of Zooplankton. I am not a biologist, so that is just a guess.

Squid Larva! Look and you can see it is swimming backwards and has swimmerets in the right place and what looks like Tentacles putting everything in the right place.

No, I am talking about the red colored rocks! lol...... ;)

It was shot in Bonaire.

An exact ID is way beyond my ken, but I'd bet on a opisthobranch in the suborder Gymnosomata. That'd make it a "Sea angel", also known as a clione, and previously known as a pteropod, which are a group of small swimming sea slugs.

On the other hand it could be a jelly that I'm unfamiliar with, but I doubt it due to the way it swims.

Um... yeah, what he said! ;)


There are so many things in the sea I never knew existed, and a Sea Angel is one of them. What a magnificent critter pictured below, whose author I cannot find to give credit to other than a screen name of bogleech.

That Horned Clione shot was taken, I believe, by either Ron Gilmer or Richard Harbison of Woods Hole Oceanographic during a cruise aboard the R/V Endeavor that I made with them back in the mid 1980s. We left Iceland, skirted Greenland, put in to St. John's and would up back at the Hole on the same day that Ballard came back from his first Titanic expedition (it was a real circus that day). Anyway, while it looks like a tropical baby, that sucker is from the arctic.

The diver who shot the original video is here now, let's see if the still photo matches what he remembers he saw and shot.

The more I look at the original video compared to the followup photos, the less I am convinced it is a clione.

I noticed a lack of an orange visceral sack that is consistent with all other videos and photos of a clione. I also noticed that the locomotive wings on the cliones are anterior, whereas the original video the undulating wing is medial, and it appears dorsal rather than bilateral.

Thoughts?

Hi folks!

I am the one that shot the video. It definitely did not look like a clione, as others have said. I was thinking squid before seeing the end folded over on itself and I never did see any separation where the tentacles would be. The single "dorsal" fin also has me stumped.

Thanks for the interest! I'll keep looking and let you all know if I find out anything.

MikeAs I said, I'm really not sure, but please do not let the lack of direct comparison to the arctic specimens that are all we have to look at (stills and the Japanese vide) dissuade you, they are all either Clione anatarcticus or Clione limnacina. It is possible that this is the only footage of this animal. I can not even find photographs of the other species known, but I will continue to search.

I can not believe that it is a squid (which was my first guess also), the single dorsal discounts that possibility.

Mike aka SeaDragon, maybe you get to name a newly discovered species!

Thanks Thal for putting me on the right track, as it became a mission!

SeaDragon, that was an awesome find.

iDiveChick, thanks for locating the right image credit.

Well done guys, I did some really basic searches, but wasn't starting with the knowledge you guys have so got nowhere. I must have watched that video clip a dozen times hoping to spot something new.
Thanks for giving me back my work day, not sure what I'll do with it, but I'm sure management will think of something! ;)

When I saw it I knew it reminded me of a chambered nautilus! Same family! Very nice research and you beat me to it, but I was closing in! Very nice video and catch! :D :p :rolleyes:

The Chambered Nautilus is Nautilus pompilius, that's Animalia > Mollusca > Cephalopoda > Nautilida > Nautilidae

This guy is in the Pterotracheoidea and has nothing more in common with the Chambered Nautilus than the fact that are both molluscs.

right, who cares about the details?! It is like the scene in Monty Python and the Holy Grail where one of the Knights of the Round Table slays half the wedding guests then the King and father of the bride admonishes the guests, upon realizing the knight is influential, to not "bicker over who killed who".

Thank you for finding that information! It is always nicer to know what it is you saw down there!!!

I was treated to another interesting encounter in Jupiter, Florida today. A pair of scorpionfish appeared to be fighting and there was a larger (female?) scorpionfish watching from above. Is this two males fighting?

Check it out...

It's called "jaw walking" and is considered to be one of the highest intensity competitive interactions that fish engage in. The same term is used for the way some snakes feed ... it's not the same thing.

The guy that started out on the left could've tapped the other one out with a fin lock early on, but he let it go ... and that female is the worst ref ever!:D
