From the Ted Talk by Edith Widder: The weird, wonderful world of bioluminescence
Unscramble the Blue Letters
There are starfish that can make light. And there are btrltie srtas that produce bands of light that dnace along their arms. This looks like a plant, but it's actually an animal. And it anchors itself in the sand by blowing up a balloon on the end of its stock. So it can actually hold itself in very strong currents, as you see here. But if we collect it very gently, and we bring it up into the lab and just seeqzue it at the base of the stock, it produces this light that propagates from stem to the plume, chinnagg color as it goes, from green to blue. Colorization and sound effects added for you viewing pleasure. (ltheaugr) But we have no idea why it does that.

There are starfish that can make light. And there are brittle stars that produce bands of light that dance along their arms. This looks like a plant, but it's actually an animal. And it anchors itself in the sand by blowing up a balloon on the end of its stock. So it can actually hold itself in very strong currents, as you see here. But if we collect it very gently, and we bring it up into the lab and just squeeze it at the base of the stock, it produces this light that propagates from stem to the plume, changing color as it goes, from green to blue. Colorization and sound effects added for you viewing pleasure. (Laughter) But we have no idea why it does that.
