I came across the documentary Deep Thinkers on BBC channel. It was about dolphins and how intelligent they are. Has some amazing footage and the dolphins as always are really cute. I have uploaded the files on rapidshare and here are the links. Please drop a line of comment if you enjoy the videos
For those who didn't watch this episode, here it is:
I have also uploaded another documentary from National Geographic here. Its called Megacities and there are 2 episodes available covering the cities of Mumbai and San Paulo. Must watch.
