Independant Learning Log 5 By Gavin Tay (11)

What I did:

I was looking through BBC, and came across this amazing article called: The organisms that glow brighter than any other

What I learnt:

- Many organisms have found ways to emit light, allowing them to glow brightly even in the darkest part of the world
- The ability to emit light is thought to have evolved independently up to 50 times
- The animals used the light to flirt, to defend themselves and even deceive one another
- How bioluminescence works -- A pigment called a luciferin undergoes a chemical reaction, generally triggered by an enzyme, that emits light
- There is no "brightest living thing"
- It seems likely that milky seas are created by masses of bioluminescent bacteria. At a critical density in the ocean they could produce an electric blue glow.
- Fireflies are not flies, but rather beetles in the family Lampyridae
- Glowworms are not worms but the larvae of a number of different insects, including flies from Australia and New Zealand, gnats in North America, and beetles across Europe and Asia

This article is mainly about organisms glowing and the chemicals behind the emission of light. This article is also about why insects are misleadingly named.
