How do dolphin brains compare to human brains?
Dolphin brains are pretty comparable to human brains; dolphins in many species have brains that are larger than ours. Humans only come out on top when you correct for differences in body weight. Even then, dolphins are typically second to us in terms of relative mass.
MRI scans have shown that dolphin brains, in relation to their body size, are about four to five times larger than any other animal of similar size.

Brain size is not the real measure of how these sea mammals compare to humans, though. What really matters is how their brains function. That's true of humans, of course. It's all of the unique ways our brains are wired that help us use them like supercomputers. Imaging also shows that the area of the brain known for higher-ordered thinking, namely the neocortex , is proportionally larger in the dolphin. That makes them different from great white sharks. In the shark, the largest brain component is the olfactory bulb, which detects scents. And domestic dogs get a little of both: A dog has a neocortex, but it's proportionally smaller than the one in a human brain. Canines have four times the odor processors of humans in their brains, though.

Scientists have long studied and learned from how dolphins use sonar to navigate the seas and objects in them. Dolphin brains also have many features correlated with higher brain functions similar to human brains. Research has shown that they comprehend language, at least certain whistled commands. Captive dolphins also have been taught to answer yes or no when asked simple questions with about 75 percent accuracy. They're using an artificial language, though, and tests of their intelligence and communication abilities continue.
Dolphins also can be social, understand some abstract concepts and recognize themselves in mirrors.

"It’s camouflaged. It’s disguised as a police telephone box from 1963. Every time the TARDIS materialises in a new location, within the first nanosecond of landing, it analyses its surroundings, calculates a twelve-dimensional data map of everything within a thousand-mile radius and then determines which outer shell would blend in best with the environment.... and then it disguises itself as a police telephone box from 1963." Doctor Who-Deleted scene-The Eleventh Hour-The Doctor explains the TARDIS to Amy

My niece and I are making some crafts, and we would like to give this one away (in the future, we are going to put them on an Etsy store). It's a 5"x5" wood block which has the design transferred on it and then sealed. You can put it on your desk, put a hook in it and hang it, nail it to a door, anything you want! If you would like to be in the give away, just share it.

 After 24 hours we'll pick a winner to send it to you!
