You've gotta be really quick if you're going to post an IOTD here. This is the first I've done since the option for anyone to post them was opened up.
We know octopi are smart. We've already got a video somewhere on here of one opening a jar. But now it seems we're finding out that they snag and use coconuts as shelter.
This *is* a pretty cool revelation, and it is being cited as a unique example of tool use by an invertebrate. Now, I'm no taxonomist, but...what about hermit crabs and the shells they glom onto? Isn't this basically the same behavior?
Nevertheless, it is an interesting view of a critter that we assume to be inferior to ourselves.
Fun video
