Defensive Bioluminescence

Bioluminescence is the production and emission of light by a living organism that is most widely found amongst marine animals and most famously in fireflies. The primary chemical reaction that occurs is the mixture of the light-emitting pigment luciferin and the enzyme luciferase. The enzyme catalyzes the oxidation of luciferin, which results in the release of blue-green light.

Ostracods, also known as seed shrimp, are small crustaceans found across a wide range of water environments. A subset of ostracods possess light organs used in bioluminescent predation defense. When attacked, the small plankton produce a blinding cloud of light that startles the predator, allowing the ostracod to escape. Here, cardinalfish can be seen eating and then expelling ostracods after they employ their bioluminescent defensive technique.

Some of the genetic adaptations that allow Tibetans to live under such harsh conditions have been mapped. They included increased production of folate which is broken down by UV light and more efficient use of oxygen.

Not sure why the title of the photo is about Venezuela, but the article is about Tibet.
