Animal intelligence has always fascinated me, and I came across a post about only 9 animals in the world that are self-aware according to the "mirror test".
I know it's not the most official of sources, but I checked and stuff seems to be more or less correct in there.
Even though they don't approach the animals on that list, I am very interested in cephalopod intelligence. As far as I can tell, octopi are the most intelligent, followed by cuttlefish, squid, and the Nautilus(not to bright at all if I recall) in that order.
Anyone aware of any interesting research into animal intelligence? Video's, pictures, and articles all appreciated. There's a smart bunch here, so I thought someone might know something about this.
