How Smart are Dolphins?

Some people believe dolphins to be second in intelligence only to humans, and lots of researchers try to discover just how smart dolphins really are. Obviously, as they can’t answer us, it’s hard to do tests, but we do have some indications. If brain size means anything, then dolphins must be very smart, as they have huge brains – second only to humans proportionally. Also, because dolphins don’t need to use up their brain dealing with gravity and balance, as they’re in water, more of their brain is free for other tasks.

Apart from all the smart tricks dolphins can do, they’ve also shown that they can think. One test, which was deliberately made too difficult, gave the dolphins the chance to choose an easier test. Amazingly, they did, showing that they can actually think about their own thinking! Dolphins can also recognize themselves in the mirror, an ability that they share only with apes and humans. Sounds pretty smart, right? Indeed, dolphins are very special creatures.
