Please see links below for videos submitted tonight by Dr. Steve O'Shea. These are 2-day-old Sepioteuthis, no more than 5 or 6 mm total length. Per Steve:

===
VIDEO 1 - An egg shot, to give an indication of the current flow required to aerate them.

VIDEO 2 - This is of a group of them huddled around the surface.

VIDEO 3 - Remarkable 45 degree angle the animal maintains itself at, even as a larva. The adults are more conventional, pretty much horizontal.

Thanks Steve! I paricularly like the soundtracks. :band:

Sorry 'bout the pixels - the camera isn't quite up to filming such tiny things through a curved tank.

The soundtrack was courtesy of the workers in the background .... nothing intentional there.

awwwwwwww cute, I didn't get the sound but I got the pics.

So you keep a fairly fast flow on the eggs then? When we had Sepioloidea eggs we were worried about the water flows so 2 or 3 times a day i would gently squirt them with a Turkey Baster!!!!

That 45 degree posture seems to be typical d'y'think?. The Sepioloidea babies, the O. warringa babies and the juv Nototodarus we've had displayed it. Did you notice if the baby Archi's did the same thing??

Anyway great video!

Cheers

More to come Jean; interesting that your larval octopus also suspended/oriented themselves at this same angle. I wonder why? Chemistry, balance, ionic distribution through the tissues, tissue density .... how bizarre that an octopus should do the same.

Yes, the larval Archi and Moroteuthis suspended themselves this way also.

Had a good hatching this morn; at least 50 additional larvae/paralarvae. About 10% of them fed on mysid shrimp within minutes of having the shrimp added to the tank; more (possibly 100's) will hatch tomorrow. Should have pics online soon. Wish I had a super-expensive (70+K) camera system. Discovery Channel have some truly dynamite footage of these things hatching (research several years ago) - they never used it :frown:

We've got about 80 larvae now, mostly 1-3 days old. They feed within seconds of being transferred from the hatching tank to the holding tank (are ravenous in fact), and are behaving in healthy-baby-squid-like ways.
