The deep sea is a world of mystery, full of creatures that hide in the darkness. However, there are some that find ways to shine a light on themselves in this hidden world. These amazing creatures use bioluminescence and biofluorescence to create dazzling displays of light that are truly awe-inspiring.
Bioluminescence is the ability to produce light through a chemical reaction within the body. Many deep sea creatures use this to communicate with each other, attract prey, or fend off predators. One of the most well-known examples of bioluminescence in the deep sea is the anglerfish. The bioluminescent lure on the end of its “fishing pole” helps it attract prey in the dark depths.
Biofluorescence, on the other hand, is the ability to absorb and re-emit light at a different wavelength. This creates a glowing effect that can be seen in the deep sea and also on land. Many corals, jellyfish, and other creatures use biofluorescence to protect themselves from UV radiation, or to attract mates.
One of the most incredible examples of biofluorescence is the glowing coral reefs. The corals themselves are not bioluminescent, but they absorb and re-emit the light of the biofluorescent animals around them. This creates a stunning display of neon colors that is not visible during the day.
Scientists are still uncovering new examples of bioluminescence and biofluorescence in the deep sea. From glowing sharks to fluorescent sea turtles, the possibilities seem endless. As we continue to explore this mysterious world, we are sure to discover even more incredible ways that these creatures use light to survive and thrive.
