    Hopefully this doesn't jinx me, but... chances are good that I'll be seeing some live deep-sea cephs fairly soon! I've been invited to join a MBARI research cruise on the Western Flyer, 22-28 March, which will be operating ROVs and other cool gadgets. The expedition is headed up by Bruce Robison and will also involve Henk-Jan Hoving, a current post-doc at MBARI (who has posted here on occasion), who has published fairly extensively on deep-sea cephs, especially reproduction; Stephanie Bush (of Octopoteuthis behavior ethogram fame, among others); and some folks from the Monterey Bay Aquarium.

    I only just found out about this so it's been a small scramble to get it sorted, but plane tickets were issued today so it looks like it's for real. Not sure what the comms situation will be on board, but I'll try to post info here as promptly as possible. Watch this space! :shock:

    Update: This cruise is part of the Midwater Ecology series and the official trip blog is here.

    Very :wink:

    ... Actually I'm guessing it will be over/around Monterey Canyon, and possibly further afield, since we'll be out for a week. More details when I know!

    Day 1! Too rough for the ROV Doc Ricketts to be out for long, but we did do a little trawl this evening at 400 and 200m (an hour each). Among the jellies, shrimp and myctophids were a few beautiful little cephs, notably Chiroteuthis, Histioteuthis (about 30mm ML) and Taonius (also about 30mm ML). The Histio is being brought back to the lab to see how long they can maintain it 8-) First photo is a gonatid (about 15mm ML).

    Histioteuthis is the little red one that looks almost like an octopus but with no external connection of mantle and head?

    Just looked it up and saw a video with a write-up that mentions the eyes being of different size.

    Since I have to keep looking up her cool finds and Kat has limited internet access, I am sharing the best of what YouTube offers. Hopefully Tintenfisch will have a actual shots to add when they make port.

    Sorry to say I don't have any photos of Graneledone (video though!), since we didn't collect any, but here are a few beauties that did come home with us. :smile: 1 - Gonatus (about 20mm ML), 2 & 3 - Galiteuthis (about 20cm ML).

    And also Taonius (about 30cm ML) and Chiroteuthis (about 12cm ML).

    Kat, can you give a layman approximation of size? I assume there are tiny but how tiny?

    Also, Denise, both the Galiteuthis and the Taonius are fairly developed, and I would say (Kat, please correct me if I am wrong) that they are probably not THAT tiny. Am I accurate Kat? The Taonius looks like it would easily be over 100 mm mantle length. They get pretty large.

    ALSO, Also. Kat, in your first round of pictures, what did you identify that larval stage in the bucket as? I have definitely seen a very similar body shape to that (as you well know). It's a shame the fin is not more in focus.

    Sorry, D, my oversight -- I've gone back and added sizes into the posts. Not all that tiny actually! The ones we get in the nets are small because the larger ones are good at avoiding, but the ones we see down deep in situ are much bigger. Here are a couple more photos from yesterday: (1) Same Taonius, (2), same Galiteuthis, (3) same Chiroteuthis.

    Aaron, in the live cranchiids you can see the blue blood being pumped around the body. It's absolutely amazing! And I'll be bringing the larval Taonius back, so you can look at their fins to your heart's content ;)
