Defensive bioluminescence
Bioluminescence is the production and emission of light by a living organism that is more widely
found among marine animals and most famous in fireflies.
The primary chemical reaction that occurs is the mixing of pigment luciferin emitters
and the enzyme luciferase.
Ostracods, also known as shrimp seed, are small crustaceans found
in a wide range of water environments.
A subset of ostracods have light organs used in defense bioluminescent predation.
When attacked, the small plankton produce a cloud of blinding light that scares the predator,
allowing the ostracods to escape.
Here, cardinalfish can be seen eating and then expelling ostracods after they
employ their bioluminescent defensive technique.
