[Featured]: Octopus living in groups and more stuff

[DWhatley]

Unfortunately, forum software removes the staring points for YouTube videos. I watched much of it and noted the octo spottings:
A pair of very small (possibly babies) at 2:30:xx and 2:39:xx
A dumbo at 7:37:xx
The best shots and almost 10 minutes of continuous video of 2 dumbos at 8:49:xx

I wonder if these octopuses are common to the area or if they migrated to temporarily warmer waters and were caught in a normal fall cooling.

Another article with thoughts by @ceph trying to analyse the bazaar behavior.

In the Line of Fire: Debris Throwing by Wild Octopuses
