This is not the new documentary, it's from the 2015, but underwater environment somehow has the calming effect, that's why I decided to watch and post pictures of it.
In this episode we saw haw amazing mantis shrimp can be it not only dances to entice the female (I approve), but also it has 16 photo receptors. A human eye has 3. So imagine what kind of spectrum of the waves it perceives. I am instantly jealous.
Also, lots of colors here are SHINee color - so you know they reign superior.
