That's the magna in magnapinna.

Do larger fins generally indicate stronger swimmers? Mesonychoteuthis also has a lot of junk in the trunk, compared to Architeuthis, and is expected to be the more aggressive hunter.

I was wondering if those huge fins might be better suited to generally slower but more efficient swimming. Could they be used for something like gliding, or as some sort of a drogue to slow the squid's rate of descent?

Thinkin' out loud...

Before answering this post, Um...., I'd like to have a little more imagery (live animal footage) of various squid swimming - especially a contrast between big- and comparatively little-finned squid species.

The enormous and quite delicate fins of this Magnapinna would certainly appear more suited to gentle gliding or hovering than they would be to swimming ... but I don't want to say that this is the case (not yet). Just call it one of those mysteries, soon to be resolved.

Done. I wasn't really expecting anything solid, given the 3(?) specimens in hand and the 0(?) observations of the things alive in the water.

Hi,

Have you any idea where or how to obtain some of those submarine videos to analyize squid swimming ?
Cheers,
Alehandro

There are quite a few snippets online, various locations, Alehandro, but from what I've seen so far you cannot look at fin morphology in isolation, relating this to an animal's behaviour; the film snippets are very much snapshots in time of a squid doing something remarkable or interesting, quite often an escape reaction, so it's hard to know what they do with their fins otherwise.

Over the next few months we intend to put series of 'swimming-squid' shots online (on Tonmo). Plans, plans, plans .... but little time.

Thanks Clem,

I have seen these video clips and they are amazing. Somo of them seems to be middle size specimens.
Something I can learn from those, in the meantime.
Cheers,

Alejandro

Well, I had a pleasant surprise last week - a wee vist from Dr Alejandro Salcedo; we sat down and talked squid all avo - twas wonderful. He's been a bit busy of late, hence his silence.

I like putting faces to names, so for those of you interested in what ceph gurus look like, well, here's Alejandro.
