The second most-intelligent creatures were, of course, dolphins

Found that very interesting

At the Institute for Marine Mammal Studies in Mississippi, Kelly the dolphin has quite a reputation. All the institute’s dolphins are trained to hold onto any litter that falls into their pools until they see a trainer, when they can trade the litter for fish. Kelly took this task one step further. When people drop paper into the water she hides it under a rock at the bottom of the pool.

The next time a trainer passes, she tears off a piece of paper to give to the trainer. After a fish-reward, she goes back down, tears off another piece of paper, gets another fish, and so on. This behaviour is particularly interesting because it suggests that Kelly has a sense of the future and delays gratification. She has, in effect, trained the humans.

The entire article is worth a read. That bit just jumped out at me

That dolphin is at least as smart as Paul Danan. Very impressive.

I had NO idea who you meant...so I googled it.

Bingo......I saw the words Celeb Love Island and Test Drive my Girlfriend and I thought....nope...that dolphin may be further up the food chain.

I think the white mice may be more intelligent then Paul Danan

Just read the whole article.

Clever buggers!

I'd say that from that quote, that not only is the dolphin aware of the future, but has in effect invented currency, and is aware that one piece of litter torn from a larger bit of litter has the same value as the larger bit of litter....that's some pretty high level thinking right there....

I bet certain whales (Jade Goody for example) would still be handing over whole pieces of litter....

The Chimpanzees at Chester Zoo are very similar, only they get rewards for rocks...

I hope Cornwall Great Whites are not as smart as these

I liked the bit about the Orca catching gulls for fun. It doesn't eat them, but pisses them off mightily.
