Title:
Detecting Fluorescence: Green, Yellow, Orange, and Red in the Deep Sea
Description:
To attract prey, this jellyfish fluoresces in the blue light of the ocean. In fluorescence, atoms or molecules absorb light at one wavelength and re-emit light at a longer wavelength, which corresponds to a lower energy.
