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.
