Cephalopods Can Pass a Cognitive Test Designed For Human Children
Cuttlefish were given a new version of the marshmallow test, and the results appeared to demonstrate that there's more going on in their strange little brains than we knew...

"Another path to intelligence". "Cephalopods are highly intelligent, easily the most intelligent of the invertebrates, by any measure. Octopuses in particular seem to enjoy demonstrating their intelligence when we try to capture, detain, or study them. In zoos and aquariums they are notorious for their indefatigable and often successful attempts at escape. A New Zealand octopus named Inky made headlines around the world when he escaped from the National Aquarium in Napier by climbing through his tank's overflow valve, scampering eight feet across the floor, and sliding down a narrow, 106-foot drainpipe into the ocean."
"Octopus brains are not situated, like ours, in their heads; rather, they are decentralized, with brains that extend throughout their bodies and into their limbs. Each of their arms contains bundles of neurons that act as independent minds, allowing them to move about and react of their own accord, unfettered by central control. Octopuses are a confederation of intelligent parts, which means their awareness, as well as their thinking, occurs in ways which are radically different to our own."
