Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.

1. She turned off the lights because she knew that she would see a phenomenon of animals making light called bioluminescence. She described that she was totally unprepared for how much there was and how spectacular it was. She saw chains of jellyfish that were pumping out a lot of light; and puffs and billows of what looked like luminous blue smoke and sparks of blue light from the thrusters.

2. The head on ships which are the toilets on ships are flushed with unfilltered seawater that often has bioluminescent plankton on it. So, if you stagger into the haed late at night and you're toilet-hugging sick, that you forget to turn on the light, you my think that you're having a religious experience.

3. They are focusing on the chemistry because these chemicals have proved so incredibly valuable for developing antibacterial agents, cancer fighting drugs, testing for the presence of life on Mars, detecting pollutants in our waters which is how it is used at ORCA. In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it has been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.

4. What makes it important for the survival of many animals is for the animals that are trying to avoid predators by staying in the darkness, light can still be very useful for the three basic things that animals have to do to survive: and that's find food, attract a mate and avoid being eaten.

5. The primary ways that we know about what lives in the ocean is we go out and drag nets behind ships. The other primary way is we go down with submersibles and remote-operated vehicles. Doing that there are bright lights and thrusters that disturbs the animals and makes then go away.

6. She was able to tell the difference between the species by the types of flashes they produced like the big explosions, sparks, are from a little comb jelly.
