Here's how this video feels to a fly.
-
(SPEAKING VERY SLOWLY) Welcome to D News.

Anthony here for D News.
-
And you know I'm all about how animals see the world.
-
In a previous video, we talked about how
-
they see colors and magnetic fields
-
and all kinds of insane stuff.
-
But now a new study in animal behavior shows some of them
-
also see things in matrix bullet time-- whoa.
-
The team measured a whole bunch of animals and their reaction
-
times based on something called critical flicker fusion
-
frequency, basically how their body responds
-
to things like flashing lights.
-
And it turns out, the processing of information
-
is tied to an animal's size and metabolic rate.
-
You know how hard it is to swat a fly?
-
That's because they take in seven times more
-
visual and audio information per second than we do.
-
The same goes for insects and small birds.
-
Dogs take in information at twice the speed we do.
-
That's why you can't get your dog into TV or a Skype video.
-
It's just seeing this weirdly flickering screen.
-
Reaction time is the difference between life and death
-
in the wild, especially for small animals
-
that are prey for just about everything.
-
So their ability to take in information quickly
-
is essential for their survival.
-
And you know how humans process information is interesting.
-
We can only take in so much at a time, but we can change it,
-
or rather, our bodies can, situationally.
-
If you ever felt like time's slowed down
-
before a car accident or a particularly
-
dangerous situation, that's your body
-
flipping your brain into overdrive,
-
so you have more ability to react.
-
Our ability to process information
-
can also be changed by age and training.
-
Athletes have a tendency to be able to take
-
in more information while playing their particular sport,
-
meaning time seems just a tiny bit slower to them
-
during a game.
-
And as we get older, our ability to process and take
-
in information slows down, meaning
-
time seems like it's slightly faster than we were younger.
-
In case you're wondering, besides flies,
-
squirrels and pigeons seem to take
-
in the most information at once.
-
The slowest animals were the European eel, the leatherback
-
turtle, and the black nose shark.
-
And interestingly, only one animal's speed
-
doesn't match its perception.
-
The tiger beetle runs too fast to keep up with its own vision.
-
It has to stop, wait a second, and then run again.
-
It is like living in a permanently buffering YouTube
-
video.
-
We've all been there.
-
Am I right?
-
If you want to know more about animal vision or any
-
of their other crazy abilities, we
-
have tons of videos about them in the links below.
