What is Bioluminescence
• When an organism emits light from its body– It can be voluntary (on purpose)– Or involuntary (not on purpose)
Some organisms that produce bioluminescence…..

Why use bioluminescence?
• Warning to predators• Camouflage• Navigation• Communication
– Finding mates• Attract prey
– Angler fish
Camouflage• Cookiecutter shark - Counterillumination. As this shark
rises closer to the surface, it lights its underside so a predator looking up from beneath does not see its full silhouette. The shark “disappears”.

Attracting Mates

Communication
Attract Prey

• Angler fish---the lighted lure attracts prey.
• Cookiecutter shark-Since only a small part of its body is easily visible, it looks like a smaller animal—attracting something that thinks it is going to get a meal, but instead becomes a meal for the much larger shark.

Why did the plankton glow?
Open your CWW Journals to pages 26 – 30 so we can talk about it!
