Dolphins may be highly spiritually evolved, but it appears that they're not too bright, being even less intelligent than goldfish, or so claims Paul Manger, of the University of the Witwatersrand:

"Dolphins have a superabundance of glia and very few neurons... The dolphin's brain is not made for information processing it is designed to counter the thermal challenges of being a mammal in water," Manger said.
"You put an animal in a box, even a lab rat or gerbil, and the first thing it wants to do is climb out of it. If you don't put a lid on top of the bowl a goldfish it will eventually jump out to enlarge the environment it is living in. But a dolphin will never do that. In the marine parks, the dividers to keep the dolphins apart are only a foot or two above the water between the different pools."
They jump through hoops only because they have been conditioned to do so for a food reward - which may suggest the brain of a single-minded predator rather than a reasoned thinker.
Manger also makes the point that, if dolphins are so smart, why do they get themselves killed in tuna nets?

First there were zombie sharks swimming down the main streets of New Orleans; now, it emerges, there may be US Navy hunter-killer dolphins on the loose in the Gulf of Mexico, waiting to start picking off unsuspecting surfers with toxic darts:

Dolphins have been trained in attack-and-kill missions since the Cold War. The US Atlantic bottlenose dolphins have apparently been taught to shoot terrorists attacking military vessels. Their coastal compound was breached during the storm, sweeping them out to sea. But those who have studied the controversial use of dolphins in the US defence programme claim it is vital they are caught quickly.
