Edith Widder: The weird and wonderful world of bioluminescence

http://www.ted.com In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self-defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.

SHANTI- I think it is very interesting in this video to see how many different animals can produce light! The part where the woman shows the video that they took in the bahamas is very cool because it shows them interacting. I found this video to be very entertaining because the presenter was very entertaining and made numerous jokes.

What happened to the first two?

If I'm not mistaken some of them (some) don't "produce" light, but when the submarine lights them up, they give out those colors because of what they are made. Do some research yourself, maybe I'm wrong :$

I learned a lot in this video about the bioluminscent creatures that inhabit the depths of the sea. I was farely unaware of these creatures but learned that many use light as a means of protection against predators that either works in scaring them or doesn't, uncovering them from safety. A question I have is how is it exactly that these creatures produce light?

Bioluminescence is absolutely going to be a future trend in cosmetic surgery someday. I should get a patent.

I found this video very interesting.It reminded me of Blue (the planet earth for the the ocean)I learnt that most underwater animals produce bio-luminescence and that they use it almost like a burglar alarm.My favorite part was looking at the shrimp because the color made was pretty.A question that I have is how does the bio-luminescence transfer to you when you brush against it (the golden coral).This is my favorite one yet!

I found this video so interesting! I did not want it to stop. I learned from the video that some animals like the single celled algae produces light to portoect and defend itself from predators. Through a fake light, when the light was shinning, a squid tried to attack the predator... but there was none. A question that I have is how do these organisms produce the light. I really enjoyed this video.
