 
- [Chuck] The German word for bats is
Fledermaus.
- That translates into flying mice.
For the curious.
- [Josh] People say that because
a bat does kind of look
like a flying mouse,
or a flying rodent of some sort.
- [Chuck] You also might
think they're like birds.
Not so.
When you look at the wing
structure of a bat and a bird
very different.
If you held your arms out to your side
with your elbows bent
and your fingers spread,
and then imagine that there was
a webbed membrane called a,
how do you pronounce it.
- [Josh] I don't know.
- [Chuck] Those are the wings.
- [Josh] Patagium.
- [Chuck] The flesh,
yeah there you go.
The flesh of the wing.
If you held your hands
out and did jazz hands,
but it was all webbed and connected,
that is way more what a bat's wing
looks like and functions
like than a bird's wing.
- [Josh] Right, so a bird's wing
has rigid bones in it, right?
- [Chuck] Yes.
- [Josh] And the muscles
that control the wings
are located basically
at what would amount to
your armpits.
- [Chuck] Yeah, like a socket.
- [Josh] So like just do
the chicken dance real quick
(chicken dance music)
and think about what you're doing.
Right, there's not really any movement
in the actual arm.
It's all in the shoulder joint.
- [Chuck] Yeah.
- [Josh] Same with birds.
With bats it's not the case,
because they're basically
like winged hands.
Which is the reason they're
order is named that.
They can basically swim through the air.
Which allows them to dive bomb
and turn and twist and go up and down
and go after these insects
that can fly really fast
which constitute most of their prey.
They are much more adept
at maneuvering midair
than your average bird is.
- [Chuck] Yes absolutely
like 1,000 times.
There's no science behind that.
- [Josh] I would
even say like 1,500 times.
Well I mean if we're
going without science.
Let's just say like a million times more.
- [Chuck] Yeah, a gazillion.
