TED video

http://www.ted.com/talks/david_gallo_on_life_in_the_deep_oceans.html

a) First of all I chose this video because I am very interested in the creachers living at the bottom of the sea. The presentation was fascinating and I enjoyed all the video clips of the creepy animals living deep in the sea.

b) Like I mentioned, the presenter uses video clips effectively to explain the creachers and also to keep the audience's attention.
I thought it would be the best visual aid in presentations like this when they are introducing new things to the audience. The presenter also used his voice tones in an effective way in order to clarify the important parts and the not so important parts in his speech. He also used several jokes throughout the speech which I thought was really important especially after long explanation of scientific facts in order to make the audience relaxed.

c) I really liked the speech and I feel that most people on TED are excellent presenters so it is hard to find the weakness of the presentation. However I did feel that there should have been a clearer division of who is going to speek what (there were two presenters in the speech.) I felt that maybe they did not discuss so much about how to separate topics because it seemed like the second man spoke in the times when he just feels like it.
