People like you finding it interesting is literally the definition of what should be posted on HN.

That said, I would love it if the OP game some additional context on why they submitted it - is this a response to something? Was there a new advance here? Just something cool they saw?

I wish here was a good way to include context with a bare link. In this case, I just learned the rat in The Abyss was actually submerged in breathing fluid, a substance I thought was fictitious. This blew my mind, so I shared.
