I see
it, I see it, I see it.

Right here, about 2 and
1/2 feet in front of me.

Let's go for it.

Got it!

The last place one would
think to look for an amphibian

is at the top of a mountain.

However, in a secluded
lake on Orcas Island,

it just so happens
that one exists.

And we were told that
all it takes to find one

is a little searching
amongst the lily pads.

All right, guys so we
have made it to the water.

I'm going to head
out across this log

and see if I can find anything.

Check this out.

It's a mountain lake Whoa.

Now, normally I'd be
excited looking for turtles.

But we are way too
high up for there

to be any reptile activity.

But I'm told there's
a chance we could come

across rough-skinned newts.

So I'm going to start
searching, and hopefully

come across one of these
elusive little amphibians.

Hey, Coyote.

Mario's got some
newts over here, man.

They're pretty big, too.

Mark and Mario have
spotted some newts.

So I'm going to move through
all this muck and mud

and see if we can catch them.

I see it, I see it, I see it.

Right here, about 2 and
1/2 feet in front of me.

Just go for it.

Go for It.

Got it!

Yes!

There we go.
Yes!

Nice.

Mario, there are
newts here, man.

Check that out.
Good spotting, Mario.

All right
- Dude.

High five.

And that is a
rough-skinned newt.

OK, let's get up
here out of the water

and get it up close
for the cameras.

Woo!

Well, that didn't take long.

Check it out.

Yeah, no question about it.

That is a rough-skinned
newt right there.

And look at that
little amphibian.

How adorable is that newt?

You see all the bumps running
along the length of the body?

Definitely.

Oh yeah, all bumpy.

Pretty crazy, right?

Hence the name rough skin.

Now, if I turn it like this
and we look at its underside,

look at that bright orange.

Oh yeah.

And notice how that
bright coloration runs

down the length of the tail.

And that's called
aposematic coloration.

And this bright color warns
any potential predator

that I am toxic.

Now, if a predator
like a raccoon or a fox

comes down to the lake and
finds one of these newts--

and let's say it eats it,
there is a good chance

that that animal is going
to become very sick,

or it could potentially die.

Now are these--

I heard these are one of
the most toxic amphibians

in the United States.

It is one of the
most toxic amphibians.

However, I'm in no
danger right now,

because the toxin which can
be secreted through the skin,

is not harmful unless
you actually ingest it.

So as long as I
don't eat this newt,

I'm going to be just fine.

And look at that.

It is on the move.

It's saying right now, OK, just
want to get back into the water

so I can start hunting
for the evening.

And what they feast on
are small invertebrates.

Any sort of larva, little
water bug, or even something

like maybe even a small
fish would be fair game.

That is one adorable
little amphibian.

Oh,
look, he's doing--

he did a back roll.

Yeah, they'll do anything
they can to get away.

It's best if I just let it
walk from hand to hand here.

Let me kind of--

Now, Coyote,
are these only aquatic?

Do they live on land
or just in the water?

Well, they start their
early stages as being

completely aquatic as larva.

And then as they get older,
like this-- this is an adult,

they can obviously go onto land.

Their semi-terrestrial,
but they spend a majority

of their time in water.

That's where they breed.

That's where they hunt.

And like most amphibian species,
they do need to stay moist.

But because this
is a newt, its skin

can dry out without having any
sort of real negative effect

to the animal.

In fact, they can travel
for miles over land,

moving from body of
water to body of water.

Now, I've
noticed, because we've filmed

with salamanders
and newts, newts

seem to be a little more
lumbery They don't move as fast.

Why it that?

No, they don't.

And you know, they're
faster in the water

than they are on land.

And as you can see, they
do not have webbed feet.

And there are four toes on the
front, five toes on the back.

And they kind of walk up on all
fours when they're traversing

across forest terrain--

much faster in the water
than they are on land.

And pretty
well-camouflaged, too.

I mean, if you didn't know
what you were looking for,

mixed in with pine cones
and sticks and pine needles,

that creature is
almost completely

invisible to the human eye.

All right, let's bring
you back up here.

little guy.

Look at those eyes--
big buggy eyes.

Looks like the eyes of a toad.

And I love that about
most amphibian species,

how to have those big eyes that
sit up on top of their skulls.

Now, look at the tail.

This is a great opportunity
for us to see how long and flat

it is.

That's like a rudder.

And when I went to catch this
newt, it took off so quickly,

it was just a burst
of power from its tail

that jutted it forward.

And I just barely was
able to grab a hold of it

and get it out of the water.

A lot faster than I
thought it was going to be.

That is one speedy
little amphibian.

Well, how cool is this?

Exploring around
a mountain lake,

and we managed to come
across one of the most

common amphibians in
the state of Washington,

the rough-skinned newt.

I'm Coyote Peterson.

Be brave, stay wild.

We'll see you on
the next location.

Oh.

Heard it.

Oh.

There-- there
he is, right here.

him in the bag

before he jumps again.

Oop, he's on my hand.

I've been waiting
to get the shot for years.

Look at that.

You can see right through the
underside of that amphibian,

I love frogs.

Always have, always will.

In fact, I don't think
I've ever met a person

that didn't love frogs.

I mean, what's not to love?

So when it comes to finding an
incredibly high density of frog

species, one of the best
places you can visit

are the rainforests of
Central and South America.

On this adventure, the
Brave Wilderness team and I

are back at the Costa Rican
Amphibian Research reserve,

where once again,
we will be working

alongside world-renowned
frog expert Brian Kubicki.

All right, guys.

Well, we just had an enormous
rainstorm push through,

which makes it the perfect time
to head out into the rainforest

and search for amphibians.

Now, we're looking
for glass frogs

tonight Not only
going to be looking,

we're going to be
using our ears to see

if we can hear them
first before we

spot them with our flashlights.

So if you guys are ready,
let's head into the darkness

and see what we can find.

Most species become
active at night.

So as we headed off
into the darkness,

it wasn't long before the sounds
of frogs were all around us.

Now, we had great rain
that pushed through.

So there's a lot of
moisture out tonight.

But I noticed so far,
we've been searching

along the edge of the stream.

Is, like, flowing
water the best place

to search for glass frogs?

Yeah, definitely.

Glass frogs, they're associated
with streams and rivers.

So what we're going
to be doing tonight,

we'll be walking along
these smaller streams,

looking in the vegetation
growing on the banks.

So we're kind of-- we'll
be going around, listening

for the calls, and then
we'll look according

to what the species call from.

OK, well,
this looks like as good a place

as any to get into the water.

So you want to lead the way, and
we'll head upstream to start?

All right.

Let's go, guys.

Watch your footing
coming through here.

And, of course, keep your eyes
peeled for [inaudible] ants.

Glass frogs are
Brian's specialty.

So our goal is to find
two species that we

could compare side by side.

And it wasn't long before
we had the first frog

of the night in our sights.

Let's go ahead and get this
one in a little bag here.

I've got one in my pocket here.

We just need simple
collection bag.

This is perfect for storing
small amphibians temporarily.

We'll bring it right back
out onto its leaf tonight.

a little bit.

You can Maybe [inaudible].

Oh!

Look,
he jumped on here.

I'm just going to put the--

Now, shine it, Mark.
He's right there.

You see him hanging off
the backside of the leaf?

There we go.

Perfect.

Oop, put him in the bag
before he jumps again.

Oop, he's on my hand.

Got him in the bag.

Hold on, let me come up.

See him in there?

Yes.

On your finger,

Oh,
he's trying to get out.

Other way, buddy.

Other way.

There we go.

OK, cool.

Oh, there he is.

I can see him inside the bag.

The dwarf
glass frog is considered common,

so it's almost
guaranteed that we

would come across this species.

Awesome, part one of two.

Now we need to find one with
a transparent ventral side.

Oh, oh, stay down there, buddy.

OK, let's keep going.

However, finding a glass frog
with a transparent ventral side

was going to be much
more challenging.

So we headed deeper
to the rainforest.

Brian's amphibian
reserve spans over 120

acres of pristine rainforest.

It's a labyrinth of
disorienting confusion.

But the good news
for us was that Brian

knew every step of it
like the back of his hand.

Eventually, we made our way
up into a small feeder creek,

the one place that
he was confident

that we would find
the tiny treasure

we had been searching for.

Oh, we got it right here, Mark.

[inaudible] right here.

Careful, Mario,
it's slick back here.

Guys, watch your footing.

It's really narrow right here.

Oh, man, I am--

Here, Mark, let me
get up to this spot.

OK.

OK,
Mario, can you see it?

Yes.

I'm on it.

See him?

Yeah.

jumps.

And--

We got him.

Nice.

That's
Oh, man, that's cool.

And it's the
green-striped glass frog.

So now we have the
two frog species

that we were looking for.

Let's get them back in
a controlled setting,

get them on a piece of glass,
and up close for the cameras.

Yes, this is awesome!

All right, guys, careful
getting back out of here.

Mario, man, yes.

With two
distinctly different specimens

in our possession,
we safely made

our way out of the
rain forest and back

to the jungle base camp.

All right, guys, and we are
back in a controlled setting.

Now, this is the only good
way to get an up-close look

at the glass frog.

And what I have right
in front of me here,

just coincidentally,
is a piece of glass.

Now, we have sanded down
the edges so it isn't sharp,

and no one's going
to cut themselves.

And what we're going
to do is actually

place these little
itty-bitty frogs

on the back side of the
glass so that we can get

a good look at their bellies.

Cool, check that out.

Now, that looks perfect.

Can you see through there?

I sure can.

Now, I also have my SOG
flashlight-- my trusty SOG

flashlight, the Dark Energy.

And once we have a frog
up on the backside here,

I'll be able to do this.

Light it up, and you'll be
able to see right through it.

Cool.

Now, what I also have is
this little container of water.

And that's because
I will be constantly

keeping my fingers moist while
manipulating the frogs tonight.

And this water
has been filtered.

It is completely
safe for the animals.

OK, you guys, ready to
bring out our stars?

Let's
see those frogs.

All right.

And right here, two little
Kermits coming in hot.

Oh, perfect.

Look at that shot right there.

See the undersides?

There is the green stripe,
and there is the dwarf.

Now, we'll get the
dwarf out first.

And let's take a look at its top
side before we go to the belly.

Does that sound good?

Yeah.

All right, now I am
going to use this leaf,

and try to gently
coax the frog out.

Now, we have worked with
some fragile animals before.

But nothing is more
delicate than a glass frog.

OK, the dwarf one is right
where we want it to be.

[inaudible] it out?

There.

Just want to try
hop on the leaf.

Oh, on my finger.

So you
got an OK shot there?

Sure do.

Let's
see if I can just get it

to hop right up on the glass.

Got for it.

Perfect.

Look at that.

Like a little,
sticky, green booger.

So cool.

So tiny, too.

Look, I will put my thumb
right up next to the glass.

That frog is no bigger
than the tip of my thumb.

And you can see--

Go ahead and zoom in
on it there, Mark.

see that side.

Look at that green coloration.

It's so vibrant, especially
under the lights.

Frogs have
a lot of personality.

Oh, they really do.

You can see-- ooh,
looking right towards me.

They're very, very intelligent.

You can see right
now, just looking

for somewhere to jump next.

I'm hoping it's going to stay
right on the glass for us.

And you'll notice the
skin is very shiny, right?

It is very moist.

And look at how
big those eyes are.

Now, one very interesting
thing about glass frogs

is their eyes rest right on
the front of their skull.

Now, this is a great chance
for us to look at this frog's

little tiny toes.

And they do have a very
minimal amount of webbing,

especially between the front
toes and the back toes.

I can actually see the bones
in the toes in the light here.

That's crazy.

Look how they can manipulate
the position of their fingers.

Look at that.

You see how these left
two here turn to the side?

And these frogs are not
only excellent at jumping,

but also at climbing.

Here, let's do this real quick.

Let's see what happens
when I light this frog up.

OK.

Ready?

Mm-hmm.

Put it, like, up at it.

There you go.

Yep, that's great, right there.

Cool.

Here you go, buddy.

Now, Coyote, why
are you using the forceps

instead of your fingers?

Well, those forceps

definitely are not
absorbing any moisture

out of the frog's body.

What I don't want to do,
because my hands are warm, is--

whoa.

All the way over the glass.
Did see that?

That was a high
jump right there.

Oh, on my arm.

OK.

The heat from my skin
will actually draw some

of the moisture from its body.

So that's why I'm using the
forceps to keep it in one spot.

OK, here we go.

yeah, see the line.

We saw the-- oh.
Yeah, here.

OK.

There we go.

Perfect.

All right, now you

can see that the upper
half of its ventral side

is not completely transparent.

The one that we're going
to get out in a second,

you can see everything
on the inside.

But from the back here, I
can see the heart beating.

I can also see the
bones in the legs.

You can see all the
pigmentation of the skin,

and it's a real great example of
why they're named glass frogs.

You can see how semi-translucent
all the membrane

is in this frog's body.

And did you guys know this?

That Kermit the
Frog, the inspiration

for the design of that
very famous puppet,

actually came from
the glass frog.

And notice-- let me
see if I can do this.

You see how each little
toe looks like it

has a suction cup on it?

And there was a great
little move there.

You see how they just kind of
hop and walk at the same time?

And when they're up
in the treetop canopy,

they're moving around from leaf
to leave hunting for insects.

Now, they are little
tiny carnivores.

They're voracious predators.

And every single
night, once it gets

dark-- they're
primarily nocturnal,

they are hunting nonstop.

And a little creature
like this can

eat bug after bug after bug.

So Coyote, we're
going to be looking at two

species of glass frogs tonight.

How many are here in Costa Rica?

Ah, Great question.

There are actually 14
described species of glass frog

here in Costa Rica.

Now, the two that we're looking
at tonight are rather common.

But there's a new one that
was just described in 2015.

And actually Brian, who we
were out with earlier tonight,

he actually discovered
that frog and named.

He's the one
who-- yeah, he classified it.

He is the glass frog expert.

Well, that's why we were
out with him tonight

to find these two species.

And I think at this point, let's
get the dwarf glass frog back

into the container and bring
out the green-striped Does

that sound good?

Sounds good to me.

OK, now lets see if
I can just get this guy

to jump right off [inaudible].

Perfect.

Let
me see if I get it

to just jump right inside here.

Here we go, and--

Pretty impressed
by the jumping ability

of these little frogs.

Ah,
it's crazy, right?

Yeah,
they can really move.

There we go.

Perfect.

Well, I can already tell this
one is a lot more translucent.

Well, yeah, and look

at all of that beautiful
speckling on its back.

Now, they get the name
green stripe because--

oh.

Kermit, come back.
Where is he?

There he is.

Right here.

Frisky little guy.

There we go.

Now, look at all the beautiful
speckling on that frog's back.

This one is so unique-looking.

And they get the
name green stripe,

because if you look right
down the center of its back,

it has a very
distinct green stripe.

Now, you'll notice the
eye structure on this one

is a little different.

The eyes actually
look a little smaller

and the pupil is a little wider.

Oh, let's bring
you back over here.

Frisky little frogs.

Yeah, they
do have a mind of their own.

It has bunch of
yellow spots all over it.

Yeah, it does.

That's really cool-looking.

And you'll notice that the toe
structure is also very similar.

And just like the
dwarf glass frog,

this is an arboreal
species as well.

I really just want to try to
get it backed up in the center

of the glass here.

OK.

OK, that's a great spot.

Now it's got this entire
glass to work its way up.

And I love that, how they
just keep their bodies

slightly off of the leaf.

And again, that
ability to not only

hop, but also hop and
walk at the same time.

Now, the green stripe
is incredibly rare.

This species was
only re-discovered

in 2004, dating back to 1952.

Between '52 and 2004,
there were only four

of these that were found.

Isn't that pretty crazy?

This is a very, very
rare amphibian for us

to be looking at tonight.

And he's back down on the table.

Let's go back up on the glass.

There you go.

Now, the only way that
we were able to locate

one of these frogs was being
out there tonight with Brian.

And his expertise for not only
being able to hear these frogs,

but then also being able
to spot them in the wild,

is unlike anything.

He is truly the
glass frog expert.

All right, now the
top side is very

impressive-- speckling and the
green-striped nose, big eyes.

But I know what you
guys are waiting for us

to see the ventral side,
where we can actually see

those internal working organs.

Shall we bring it around?

I've been waiting
to get this shot for years.

All
right, let me delicately

get it back onto this leaf.

There we go.

That's good, and
get ready for it.

Here comes the jump
and the reveal.

Look at that.

Oh boy.

You can see
right through the underside

of that amphibian.

All right, let me--

oh no, you need
Oh, where you going?

Kermie.

That's a cool shot.

It's really cool.

Hold on.

I'm going to bring
it back down here.

I don't want it to jump
off and on to your camera.

OK, I'm going to
get it back on here.

I'm going to actually give
it a little dip of water

here, since you
got off the glass.

There you go, buddy.

All right, here we go.

Here comes the hop.

They're so incredibly
lightweight.

Oh, there's a great
shot in the leg there.

Oh, and he tucked it back in.

You can see when I get the
light right up to the leg,

you can see right through it.

You can see the
skeletal structure.

You can see the insides.

Oh, that's so cool.

Coyote, I got to
tell you what I'm seeing here.

I'm actually
looking at the heart

filling and pumping blood.

You can actually see the blood
moving in and out of the heart.

That's so cool.

You can see some of the arteries
through there, can't you?

Oh yeah.

You can see
on the back side of the leg.

I can kind of see some
through on this side.

You can see the
whole digestive system.

You can see all the
vascular system.

You see it all.

You can see everything.

I
would say out of any

of the amphibians
we have ever filmed,

this has got to be the coolest.

Look at that.

Right there is the most
quintessential textbook

shot that you can
get of a glass frog.

Man,
I've been waiting

to shoot this for so long.

This is so cool.

Well, we have
been to Costa Rica many times.

And now we finally
have the opportunity

to work with a glass frog
that has a completely

transparent ventral side.

Now, this one here is a male,
and what's really interesting

about the species is that the
males actually take care of

and look after the eggs.

Now, they oftentimes
will lay their egg masses

on low-hanging leaves
near flowing water.

And when those eggs
hatch, the tadpoles

drop down into the water,
and that cycle will repeat.

Now, let's look at
the size of this frog.

I'm going to hold my
thumb up right there.

It is no bigger than a thumb,
and this frog is full grown.

Now, the largest glass frog
species here in Costa Rica

only grows to be about
3 centimeters in length.

But there is one
in South America

that grows quite a bit larger,
if 8.4 centimeters is larger.

I mean, it's certainly nothing
like the smoky jungle frogs

that we've come across
here or the bullfrogs

that we've seen in the States.

But doesn't matter.

Size is not everything when
it comes to being adorable,

because this frog is
absolutely the cutest amphibian

I think I have ever seen.

Wow, this was so cool.

Well, it's taken us several
trips to Costa Rica.

But we finally managed
to get the tiny glass

frog up close for the cameras.

I'm Coyote Peterson.

Be brave, stay wild.

We'll see you on
the next adventure.

Working with amphibians
is a difficult balance,

as these fragile
creatures must always

be handled with incredible care
to ensure their well-being.

Under Brian's guidance
and expertise,

we managed to not only
get the images we needed,

but also safely
release the frogs back

into the same locations
where we had found them.
