Many animals, especially insects and deep sea marine species, produce light to send signals to those around them. This is called bioluminescence. In this clip from the 1973 CHRISTMAS LECTURES “The languages of animals”, Sir David Attenborough performs simple chemistry to show how some animals put on these vibrant displays.

The world needs these entire lectures available to all on youtube.
David Attenborough is a legend.
This and That.
Love this series. Like to see full shows. (maybe I need to look into that)
You may be cool, but you'll never be David Attenborough cool. And that's OK.
Squirt.
1,2,3 Squirt!
How about that?!
Meme machine ahead of his time!
Hahaha he can only count to three. Stupid scientists . Trump can count to that there number that comes after 3.
I studied biology in college and this amazing man os partly responsible for why I chose biology. A bigger than life teacher and educator.
I am not sure how did this happen, but I am going to assume that a chemical reaction takes place which is responsible for releasing photons that create light.
David ma boi!
Was that a singlet oxygen reaction?
(:
Attenborough the showman.
… I hope this is a teaser trailer for the whole show!
This kills the flask
Its a great idea having the Lectures on YouTube.
