Big Pictures Of Mars

Sounds like a band name, but it's actually just Big Pictures of Mars.

Like this, but bigger:

Dolphins understand delayed gratification

I will omit the Carl Sagan bit about the fantastically complicated mechanisms involved in cognition. Just pretend that was here, and then read the regrettably-titled Deep Thinkers (at guardian.co.uk).

Important paragraph:

One day, when a gull flew into her pool, she [Kelly the dolphin] grabbed it, waited for the trainers and then gave it to them. It was a large bird and so the trainers gave her lots of fish. This seemed to give Kelly a new idea. The next time she was fed, instead of eating the last fish, she took it to the bottom of the pool and hid it under the rock where she had been hiding the paper. When no trainers were present, she brought the fish to the surface and used it to lure the gulls, which she would catch to get even more fish. After mastering this lucrative strategy, she taught her calf, who taught other calves, and so gull-baiting has become a hot game among the dolphins.

Immediately reminded me of the apparent importance of strategic meta-thinking - and delayed gratification in humans, for example the famous Stanford "marshmallow test". See also, which seems to incorrectly state that this is an exclusively human behavior.
