Bioluminescence in Nature

The video explores bioluminescence, the phenomenon where living organisms emit light. It discusses how fireflies use light for mating, ostracods for defense, and sea sparkle for deterring predators. The crystal jelly's unique green glow is highlighted, along with its scientific applications, such as GFP in research. The video concludes with acknowledgments to viewers and patrons.

What is the primary reason fireflies use their glow?

• To scare away predators

• To find food

• To navigate in the dark

• To attract mates

Which protein is responsible for the light emission in fireflies?

• Aequorin

• Luciferase

• Luciferin

• GFP

Why might fireflies have evolved to produce different colors of light?

• To attract different species

• To signal danger

• To match the colors of their environment

• To confuse predators

What unique defense mechanism does the ostracod use?

• It changes color rapidly

• It emits a foul smell

• It releases a glowing substance
