00:33 Why don’t you tell your friends about me?
00:36 Good idea! So guys, today let me tell you all about fireflies!
00:42 Zoom in!
00:45 So, you might be wondering why do fireflies glow?
00:49 There are various reasons to it.
00:52 Some glow to appear distasteful to their predators.
00:55 because a chemical called lucibufagin, which helps them glow.
01:01 Doesn’t go well with the predator’s taste buds, it does taste pretty gross.
01:09 Well, some of them are sort of flirty.
01:14 They have a specific pattern of flashing light to their love!
01:19 The males use this pattern to let a female know that they are interested in them!
01:26 And if the Female lets out a similar lighting flash in response,..
01:33 ..then the fire of love ignites between them!
01:38 How lovely!
01:41 Oh, and also, they are 100% light givers!
01:45 Confused right?
01:47 Well, when a light bulb lights up, it gives out 10% light.
01:52 And the other 90% is lost as heat.
01:59 But when the fireflies glow, they give out 100% light!
02:06 Super efficient, aren’t they?
02:09 Now you’d be wondering as to how do these fireflies glow?
02:13 Are they magical or do they have some super power?
02:19 No! Its all chemical!
02:24 They have a chemical called Luciferin inside their tails..
02:28 ..along with an extra oxygen electron..
02:31 ..combined with calcium and adenosine triphosphate.
02:36 Which contribute to a chemical reaction that sparks up their bioluminescent light!
02:43 TRIVIA TIME!
02:45 Did you know some fireflies are cannibals?
02:49 Yes, they eat other fireflies for food!
02:54 Some firefly larvae live under water.
02:57 They have gills to help them breathe!
