So insects, birds, they've all got this.

Turns out cows have good magnetoreception as well.

There's, you know, some animals see in the infrared range.

So rattlesnakes, for example, they have these heat pits and they're picking up on infrared radiation.

Others like honeybees see in the ultraviolet range.

These are things that are just totally invisible to us.

We don't pick this up at all.

And I've been studying this for many years because I'm fascinated by the idea that there may be things that animals are picking up on that we can't even get.

We're not even going to know for the next 50, 100 years when someone realizes, oh my gosh, it turns out antelope are picking up on this thing that we didn't realize was a thing.

So

When you really study the biology across the kingdom, you find that there's lots of information out there and we are extremely limited.

And I think this is a very counterintuitive thing to think that your biology actually constrains your perception of reality.

Oh, yeah.

And by the way, sounds, yeah, there are lots of animals that hear in what we call the infrasonic range and the ultrasonic range.

So we hear from, the details don't matter, but from 20 hertz to 20,000 hertz.

Don't worry if you don't know that.

But it's just, that's the range of human hearing.

But there are animals that are communicating way above that and having conversations all the time, lots of insects and frogs and whatever.

And elephants are communicating at the ranges below that.

They're feeling it with their feet in the ground.
