Among living things, the color blue is oddly rare. Blue rocks, blue sky, blue water, sure. But blue animals? They are few and far between. And the ones that do make blue? They make it in some very strange and special ways compared to other colors. In this video, we’ll look at some very cool butterflies to help us learn how living things make blue, and why this beautiful hue is so rare in nature.

You never notice how rare blue is, until you do, and then you (don't) see it *everywhere*.
Leave a comment and let me know what you thought of this week's video! And commence the blue-pun party
nerd
I saw a bunch of light blue WASPs last summer around my house. They looked like they were spray painted light, blue metallic…so alien-looking.
Actually that's not true, here's a list of things which are blue in nature :
Blood of hermit crab
Sea water appears to be blue due to refraction but still it exists in nature
Turquoise stone
Aquamarine stone
Eyes of Caucasians due to some genetic mutation
Blood of hermit crab
Fingertips and lips of a person with severe tuberculosis
Some mosses with the ability to glow in the dark have blue colour
Cyanobacteria or blue green algae have bluish tinge
A person who becomes poisoned become blue colored
A baby deficient of oxygen obtains a bluish tinge
Petals of clitoria ternatia
Certain mud crabs have blue colour
A variety of krill has blue colour
Octopus and Squids release blue coloured ink when provoked
Blue dye is obtained from indigo plant which by itself has blue pigment
Some cases of waardenburg syndrome may cause albanism in eyes and thus becomes blue
These are just a few
What about dolphins and blue crabs
have you ever looked up?
This is the first video I've seen on your channel and I am thoroughly impressed.
so then shouldn't it be equally hard to make a blue pigment as it is to make a green one, or any color for that matter?
0:06 but but what about maltese tigers. stop crushing my dreams ok
So if its the structure could you change someones structure so their eye color could change from whatever to blue
cool Lego bird!
The explanation on how animals were not able to adapt to the blue was unclear. The way it was explained also suggested that they evolved these structures on purpose, as in rationally. Making the video irrelevant to the title.
Why?
Nature ain’t crips 😭🤷🏾♂️
That honestly BLEW my mind hahaha WTF!?
I've had people say to me, but why do some colors go from blue to green in different light
Can chameleon turn blue?
There are blue ISH dogs
yes
But those butterflies are white and gold…
Why are blue berries blue then 😂 is it pigment or how it’s structured?!??
