Well it's a bit of an oversimplification but it's mostly right. This came up in my rss feeds and I had to share it, I'm sure some of you guys will find it interesting.
You may or may not have been aware that dolphins are an animal that uses echolocation to identify objects in their environment. Basically they emit a clicking sound. Based on the pitch of the sounds that bounce back off an object, they are able to "hear" pictures.
What you probably didn't know is that once they hear the response, they're able to replicate the pattern and send images to each other. There's also research being done into viewing these images the dolphins make, as well as actually communicating images with them.
Here is a link to the article.If you look you can see that the image the dolphin generated of the flower pot contains remarkable detail - even the textured bands in the bottom of the pot are visible. Whether they can see the pot in that much detail, I'm not entirely sure, but it's still really cool. They're able to communicate all kinds of information about shape, size, and texture in a couple of clicks. See this post by Colten for the outline of the flower pot.
