Bioluminescence firework

Physicist and BBC presenter Helen Czerski uncovers an amazing light phenomenon, a bioluminescence firework that issues when a cardinal fish swallows ostracods. “It’s like a little fish firework.”   Watch the video…

Ostracods are very small ocean living animals. which produce light when they are disturbed (eaten).

When are swallowed, they emits a burst of light, making the cardinal fish spit it out, like a bioluminescence firework.

The cardinal fish is doing so as it does not want to be seen by other, larger predators.

Dr Czerski, said:

“Their dazzling glare acts like a security light.”

The process is known as bioluminescence, an adaptation allowing animals to be seen in the complete darkness of the deep sea.
