Dosidicus hunting in the shallows in daylight?

I came accross this interesting blog entry, intriguing statement, supported by 2 nice photo's of Dosidicus, somewhat out of the ordinary...

And yes, jumbo has become giant, once more, sigh :roll:

Another possibility might be that this is related to the mass strandings we see from humboldts occasionally, and that it really wasn't all that healthy. Still, the idea that Dosidicus gigas forages in shallow sand is appealing.

Rather bizarre; not what I would have considered to be normal ommastrephid behaviour. It likely has jetted water through to funnel to help excavate that depression within which the head, arms and tentacles are sitting, though why it would do this in such shallow water is beyond me.

I have observed Humboldts in shallow water in the morning about 9am patrolling the shoreline. They went back and forth several times and did not strand. I think that the small ones will cruise the shallows for the blue crabs or flounder in close.

I saw two last month in two feet of water in front of my house. There were a couple of them beached at the time though. the ones I observed in Gonzaga Bay in Baja CA were no injured and were cruising in formation in 1m of water on the edge. It dropped off to 6m very quick then stays about 10m to the edge of an underwater canyon about 3 miles to the south. They did not appear distressed in any way and you could see the eye rotate up at you when they swam by.

I dont know what it means I can only report my observations

Dale,
I wonder if you put bait out every morning if you could "train" them to visit daily. I was thinking about something like the racoons and skunks in the parks that get used to humans feeding them ... Then you could get out the camera and SHARE some of your "observations" ;>)

If they could indeed be "trained" to recognize that they are being fed in a certain area at a certain time, you could also see whether or not more will actually come in to the coastline to the feeding site, which might reflect on true pack behavior and possibly communication of some sort.

Those are great ideas guys, but I have only seen Humboldts close to shore 5 or 6 times total in my life. They seem to be on the move when I see them looking for something. There are lots of shrimp boats around now and the fishing is real good. They were all small ones 1m and under.

If I see one in front of the house again I will take a pic of it. My wife saw one when she was out looking for clams and scared it to deeper water because she was afraid of the gulls sitting on shore waiting for the little humboldt to make a mistake.

From what I have observed the Humboldt seems to take any opportunity to feed on anything it can. If it means heading into the shallows to eat a blue crab or flounder when you are young, well then I think that they are more than capable of doing it. Who knows maybe the small ones spend lots of time in the shallows before they go deep when they get older?

Like I said, Im not a researcher I just report what I see.

Dale,
I was not trying to turn you into a researcher, I just wanted a member with a Humbolt as a pet!
