Neat! I've "stuck" this thread so that it shows up on the homepage. Prior experiments observed that over time, the octopus is able to open the jar with more and more ease (i.e., they have excellent short term memory). It would be interesting to learn what you observe in terms of how long it took him to do it, and whether you see him doing it more quickly going forward.

yeah this time it took him a while to figure it out but i plan on him having to do it to get his food from now on... and i want to try different containers and throw in little twists when he really gets it. like a jar inside a jar or something.
i will definatly keep all of you updated to how it goes.

They are smart! My brother and I used to spearfish for them in Italy when we lived there. They can fit themselves is the smallest places and can outsmart even the smartest and most experienced spearfishermen out there. It does not surprise me one bit that it can open a jar and it could possibly open a tuperware container. I recommend trying one and seeing if it can open it. Thank you for sharing! :smile:

If you follow the eNature.com link to show all cephalopods there is an interesting note about bimacs:

"In 1949 it was discovered that there were two closely related species of two-spotted octopods instead of one. The second was named the Mud Flat Octopus (O. bimaculoides). This is the species most commonly found between high- and low-tide lines, on mudflats as well as among rocks. Its arms are shorter, 2 1/2–3 1/2 times mantle length, and its eggs are larger. However, the first clue that there were two species instead of one was offered by the discovery that there were two different populations of kidney parasites (mesozoa) in the Two-spotted Octopus. It is noted that the males and females at breeding time have no trouble distinguishing between the species."

Must be how we can tell the difference between an American and a Canadian, even if it is just the accent. We live close together but there is still a difference.

:wink:
