Mark, come here!

What is it?

Hurry up, hurry up!

What do you got?

Oh my gosh.

Wow.

I can't believe that I
just caught this creature.

Hold on just a second.

I'll peel back my hand.
Look at that.

Do you know what that is?

Today the crew and I are
exploring a lush valley cut

into the center
of the Costa Rican

amphibian research reserve.

This biological safe
haven spans over 100 acres

and is home to many species of
birds, reptiles, amphibians,

and countless creepy crawlies.

Wow.

Look at those ants.

I don't know what
species that is, let's

find out if they bite or sting.

Ooh.

Yep, they bite.

Look at that.

Embarking upon an adventure
into the rainforest always

fills me with a
sense of excitement.

The terrain is incredibly
challenging, especially

when breaking trail
into the unknown,

and whether it's slippery
rock strewn riverbeds,

or the disorienting
maze of endless trees,

the adventure is always epic.

When it comes to
finding animals,

doing so in a rainstorm
is incredibly challenging.

However, sometimes it's the
flooding of the forest floor

they can actually bring out
the rarest of creatures.

Mark!

Come here!

What is it?

Hurry up, hurry up!

What do you got?

You are
not gonna believe this.

Oh my gosh.

Come on.
Wow.

I can't believe that I
just caught this creature.

Hold on just a second.

I'll peel back my hand.
Look at that.

Do you know what that is?

Whoa looks like
a giant earthworm.

He's actually an amphibian
and it is called a Caecilian.

Let me get out of
the leaves here.

Oh, I can't believe that
we just caught this,

and I bet you the
reason that I even

saw it was because there's so
much water moving through here.

See if I can just lay
it out on my hands.

Wow.

That is one of the most
bizarre animals you will ever

come across in the rainforest.

Wow.
It is slippery.

Looks fast.

Look at that, it just
tied itself into a knot,

and actually this
end is the head.

Look at that.

I can't keep it in my fingers.

It is like a slippery
water balloon.

Is it slimy?

It is incredibly slimy.

Put your fingers out
there and feel it.

It feels just
like an earthworm.

It does.
It does.

It looks like a mix between
a snake and a giant worm.

Even the little rings
in this animal's body

make it look as if it has
segments like an earthworm,

but in fact that is just
the pattern of its skin.

You could search for years
out here in the rainforest

and never come
across one of these.

You literally have to
dig in the leaf litter

or deep down into the
Earth to find them.

This is one of the most
incredible fossorial creatures

that we could have possibly
come across, and it is so--

I'm sorry to stop.

The camera is getting doused.

I'm afraid we're
gonna lose the camera.

Dude, we have to
film this animal.

I know.
- OK, I got an idea.

Mario, hand me that
plastic container.

We always have a
container with us

in case we need to put
an amphibian in it.

I think what we do, let's
actually take the caecilian

to a more controlled
environment,

get some macro shots,
get you guys an episode.

The odds of us ever coming
across one of these again,

probably slim to none.

So we'll bring it back here
to release it, but let's

get ourselves where we're not
getting soaked by the rain

because, yeah, you're going
to destroy your camera,

aren't you?

Yeah, just saw a
raincloud go over.

OK, let's let's cut
the camera and let's

continue the scene in
a controlled location

Oh this is so cool, though.

Mario time to
pack them up, man.

Let's go.

And we are back.

I'm going to take off my
pack for this one right now.

We are at a little
jungle research station.

This is great, going
to keep the cameras

and myself out of the
rain for the scene,

and in that container
is the caecilian.

There it is.

Oh, slippery little
noodle right there.

Wow.

The skull is very
very rigid, and that

is what allows these
creatures to dig underground.

They are fossorial
and the body is filled

with all these tense
tendons and the way

that they travel underground is
almost like a hydraulic piston.

It will drive its head into
the soil using all the power

from its body, and then once
it's made some progress,

it will then slink its body
forward, almost like a worm.

Wow.

It is so strong.

It's taking actually quite
a bit of strength just

to hold it in
position like that.

They do have eyes.

The eyes are very, very small.

Let me see if I can see them.

But they have eyes,
they have nostrils,

and they have these little
tiny tentacles right up front.

Actually, I can see
that in the light there.

Those are chemical
receptors that

help this amphibian
sense what it

is after when it comes to prey.

They feed on little
earthworms or termites.

Now, there are around
200 species of caecilians

worldwide, and of those
species, around 75%

give birth to live young.

This is really interesting,
and a fact I'm sure most of you

didn't know.

The females actually stay with
the youngsters to protect them,

and as she is protecting them,
she develops an extra layer

of skin on the
outside of her body,

and the youngsters feed on
it to nourish themselves.

It's very high in
nutrients and fat.

How gross is that?

Eating skin off your mom, right?

Ew.

This is so bizarre looking.

They do get quite a
bit bigger than this,

and there are some species that
can grow up to almost four feet

in length, and then, of course,
there are some that are smaller

that are only a few inches.

This one is just a little
less than a foot long.

Look at that, I can just
slink through my hands.

Now they do secrete a mucus from
the sides of their body, which

helps them navigate underground,
but it also is slightly toxic,

so I am going to
have to wash my hands

after handling this amphibian.

Look at that.

Look how I can just
slink through my fingers.

There is some research
that's been done on them,

hence how I know the
facts that I know,

but because they're
subterranean,

it's very rare to
ever come across them,

so it's tough for research
teams to find them.

You could spend months
digging in the jungle

and you literally have
to be in the right place

at the right time
to come across one.

Are all caecilians
this color, are they

all dark like that?

Oh, no.

I mean with nearly 200 species
worldwide, some of them

are very brightly colored
blues and yellows.

I would guess probably
aposematic in coloration,

because like I said, they are
slightly toxic, but this one,

just kind of purplish.

It would blend really well into
this rainforest leaf litter.

You look around us
and everything is very

similar to this coloration.

I was excited because
I've never seen one before

and I knew that everybody
out there watching

would love to see
this unique amphibian.

How cool is this?

Yeah.
Wow.

All right, well let's get
it back into the rainforest

and see what else we can find.

I'm Coyote Peterson.

Be brave.

Stay wild.

We'll see you on
the next adventure.

Going to take my pack.

I've come across some
bizarre creatures,

but to have gotten a caecilian-
an animal that almost never

comes to the forest
surface- up close

for the cameras was a moment the
crew and I will never forget.

We released the animal right
where we found it and managed

to capture on camera some of
its natural and very rarely seen

behaviors just before it
disappeared beneath the leaves

and back under the ground.

The Brave Wilderness
channel features plenty

of dangerous animals, from
snapping turtles and grizzly

bears to water moccasins
and tiger sharks,

so trust me when I
say that featuring

a non-dangerous species is a
welcome breath of fresh air.

Today we are back on
location in Japan,

and while I know you were all
waiting and heated anticipation

for this- here we go- before
we even found the giant hornet,

he stumbled upon another
one of Japan's giants

that is far less painful
to interact with.

Toad!
Toad!

Toad!
Where?

Right
there, right there!

Look, look, look.

Wow.

Do you know what that is?

That's a big toad.

It is a big toad.

That's the Japanese Common
Toad, a native species.

We're usually used
to seeing toads-

He's getting away.

Come here.

Oh, buddy.

Look at you.

Oh, hear that little chirping?

Oh, Wow.

Holy mackerel, that is
a cool looking toad.

OK, I think we definitely
need to film a segment

with this one.

Here, let's step back just a
little bit, onto the trail,

and get it in a
controlled situation.

Wow.

How about that?

That is the Japanese Toad,
one of the coolest-looking

amphibians that you will
find here in this country,

and it's a pretty
good size, too.

Now when we're talking
toads, the females oftentimes

grow larger than the males.

To be honest with
you guys, I can't

tell if this is a
male or a female,

because they can get
bigger than this.

And look at the
coloration, so distinct.

Look at that bright
gold that runs

all over the body,
the black speckles,

and I love this dark line
that runs just behind the ear

and down to the belly.

Speaking of the
belly, check this out.

Come here, little toad.

Look at the speckling
on the belly.

Oh, wow.

Look at that pattern.

Pretty
cool looking, right?

Oh, look at that
pudgy little belly.

Now these toads are
opportunistic feeders,

and they will eat pretty much
any little small arthropod

or crustacean that they
come across in the forest,

and these toads are
always out on the move,

and you can see this toad
is just going to climb here.

I'm going to let it
climb from hand to hand.

That's going to be easier.

It wants to move.

You see how they climb.

Oftentimes, as
compared to hopping,

hopping is usually used by
toads to escape from a predator

quickly.

In this instance, the Toad
is just feeling "All right,

I'm going to climb
from spot to spot,

up the mountain of
Coyote's hands."

Now they have incredible
eyesight, both during the day

and at night, and in a very
heavily canopied forest

like this, this toad is going
to be hunting at any opportunity

that it gets.

When it comes to
predators, most things

avoid toads because, as we
know, they are poisonous,

and that poison comes
from the parotid glands.

This one's got some
pretty prominent glands

just above the ears there.

You can actually see
the little pores.

Now, if this toad was
feeling extremely stressed,

or let's say it was an actual
predator that was trying to eat

it and I bit down
on the toad, it

would secrete that poison, which
of course, is toxic and has

a very, very nasty taste.

This Toad is feeling
very calm right now.

I just love the bumpiness
to the toad's skin.

What's really unique about
this species specifically,

is that during the
breeding season,

the male skin will
actually get smooth,

so it would look
more like a frog.

Look at those four limbs.

Oh, buddy.

It's like a Popeye Toad.

It is, and
it's starting to puff up now.

It's saying "All right, just
let me back up into the forest."

But before we do,
look at these legs.

Strong muscular legs.

You can see those rear feet
there have a little bit

of webbing, and
unlike frogs, toads

are primarily terrestrial,
which means they're moving

through the forest,
over logs, over rocks,

and they're excellent climbers.

A toad like this,
when it needs to hide,

or if it wants to
sleep, it will burrow

down, probably up under a
rock, like where we saw it.

That could be this
toad's territory.

Had perfect opportunity
with some water flowing

through there, lots of
plants, lots of soft mud,

a perfect place to
search for food,

and of course, to hide or sleep.

So, are these
toads common, Coyote?

Yes.

In fact, they're
oftentimes called

the Common Japanese Toad.

Of course, us being able to
find one was just right place

right time, but
from what I know,

yes, this is a fairly
common species.

Despite the fact that its golden
coloration- let me turn it

like that, take a good look
at the color of that toad-

it still manages to
hide incredibly well

amongst all the
fallen pine needles

and the light and the shadows.

Now one thing that I
often notice with toads

is they have a tendency to
pee on you, and of course

that is a defense mechanism to
get something to let go of it.

But so far, this Toad
has not peed at all.

It's been
talking to you, though.

Yeah,
it's a little talkative.

Oh.

And as soon as I say that,
as soon as I say that,

the toad just opens up.

That's a lot of toad pee.

I'm not worried about this
animal becoming dehydrated,

because if you can hear, there
is river in the background,

and this environment is
incredibly saturated.

At this juncture, the
toad is pretty much

saying, "OK, I've had enough
time in front of the cameras.

Please place me back
into the forest, which is

exactly what we're going to do.

But how cool was this,
coming across bufo japonicus,

one of the coolest
amphibians in all of Japan.

I'm Coyote Peterson.

Be brave.

Stay wild.

We'll see you on
the next adventure.

Definitely going to
need to wash my hands.

All across the planet, toads
seem to hop across our paths,

and I seem to never
lose my excitement

for these fascinating
terrestrial amphibians.

The Japanese Giant Toad
is without question

the most brilliantly
decorated species

we have ever encountered.

These adorable yet
potentially toxic

animals are, for the most part,
completely safe to interact

with.

Despite their warty appearance,
they cannot give you warts.

However, if you do
catch and admire a toad,

no matter what the
species, always

wash your hands after you have
released it back into the wild.

What's going on guys?

OK, so in the saga of the blue
frog which I know many of you

have seen that episode, I am
back on Middle Bass Island.

I'm completely unprepared,
no camera team, no nothing,

but I came out.

Just for the heck
of it decided to see

if I could find the blue frog.

I did not find the one that you
guys saw on the previous trip,

but I found this
frog, which also

looks like it may be some
sort of genetic abnormality.

It has crazy blue coloration
and lighter green speckling.

What we're going to do is hold
on to the frog until daylight,

so we can get a
better look at it.

This is awesome.

In the summer of 2020,
I came upon a sight

I never expected to see.

Dude, that is a blue frog.

Look at that frog.

Right there.

Oh my gosh, we've got
to catch the frog, guys.

I can't believe
what I'm looking at.

This is insane.

For three days, Mario
and I pursued this frog

day and night.

We attempted to catch and share
this beautiful blue beauty

with the coyote pack.

Yet this super spring
loaded creature outsmarted,

outmaneuvered, and
outplayed me like no frog

I had ever been witness to.

Coyote Peterson was truly
defeated by a blue frog.

I can't believe
that just happened.

I returned to the
scene of my defeat

several times in
the following weeks,

but the blue frog was
nowhere to be found.

The Phantom of Middle
Bass had disappeared,

and the legend was born.

Then, on a random trip
back to the island

without any expectation of
seeing this legendary frog,

and with no proper camera
team, a new blue was spotted,

and I totally redeem myself.

OK, guys, so here's
what's happened.

Last night, I was
out investigating

the same swamp where
I had seen a bullfrog

once before, a blue bullfrog.

You may remember an
episode from a few weeks

ago called "Blue Frog,
must see it to believe it."

Well, I didn't anticipate seeing
that frog again, considering

I had scouted one other time.

I was back last night,
and lo and behold,

I found a different blue frog.

No, this is not
the same blue frog

that evaded capture last time.

This is another example
of a frog that has

gone through a color mutation.

It's not so much why
is this frog blue,

it's how did this
frog become blue?

It is blue because it
has a color mutation

known as axanthism.

Think of it like this.

If you're mixing
colors together,

blue and yellow make green.

The base layer of
bullfrogs is actually blue,

but this frog lacks a yellow
pigmentation in its skin.

If the base is blue, and
the second layer is yellow,

when those mix
together, that is why we

perceive frogs as being green.

This frog has a lack of
that yellow pigmentation,

which is what makes it
appear to be sapphire.

Now, color abnormality
like this can

be rather frequent in nature,
and it happens quite often

in different amphibian
species, not only of frogs

but also in salamanders.

Although scientists predict
that finding a blue bullfrog

is about one in 30,000 frogs.

I definitely consider
this quite the anomaly,

and a pretty incredible find.

The reason I'm guessing that
there is genetic mutation

happening here on
Middle Bass island

is because this
is a very isolated

population of bullfrogs.

There are very few predators
other than herons and snapping

turtles in this environment,
which is allowing these frogs

to just continuously reproduce.

There are hundreds of thousands,
if not millions of bullfrogs

living in this marsh,
so after a while,

it's not unlikely
that there's going

to be some sort of mutation
that happens where you have

a color variation like this.

I think we all remember
the sapphire crayfish,

and I think it would be
rather fitting to call

this the sapphire bullfrog,
but just so we're clear,

this is not a new species.

It is a true bullfrog, it
just has a color mutation.

The more this frog
is out in the sun

warming itself up to the day,
the brighter that blue color

is going to get.

When this amphibian is
cold, or it's hunkered down,

they have the ability to
shift the chromatophores

in their skin,
which of course, can

help keep them more camouflage.

The problem a blue frog
like this faces is that

it cannot camouflage properly.

I'm actually really pleased
to see that the frog has grown

to this size to begin with.

A lot of animals that do not
have the proper coloration

for their environment end
up being easily predated

upon by other predators.

The way that I caught this frog,
which actually happened off

camera, is I did shine
it with a flashlight,

but it wasn't in the water.

It was actually up on land.

I used a long
extendable net, got

the net over top of the frog.

I was able to quickly
pounce on top of it

and get it scooped up.

What I want to do
now is give you guys

an up close comparison
between the blue bullfrog

and a normal green bullfrog.

These are the exact same
species, about the same size,

but you'll notice how different
looking the blue mutation

is from the green one.

Let's start with the eyes.

The eyes of the green bullfrog
are bright amber in coloration

surrounding that
black pupil, but

the blue bullfrog's
eyes are almost

completely black and brown.

That, again, has to do with
the lack of yellow pigmentation

in this frog's body.

When it comes to camouflage,
there's no question about it,

the green frog is going
to blend in much better

within a swamp or marsh
environment, with lily pads

and duckweed.

The blue bullfrog, especially
when you turn it sideways

like this, you can see is so
much more likely to stand out

amongst a green environment.

My theory on that, as to
why I was unable to catch

the blue bullfrog last
time, is that they're

more agile and more in
tune with any movements

within the environment.

The second they feel
the water shifting

or a difference between
light and shadows,

they immediately think, "Oh no.

I'm no longer hidden.

Something's getting close.

It may eat me.

I better spring off into
action and find myself

a better hiding spot."

I wonder if they're talking.

Saying to themselves, "What
are we doing right now?

Are we being filmed?

Were we abducted by aliens?

Are we about to be
famous on YouTube?"

Without question,
this blue bullfrog

is probably going to
be the most famous

frog we have ever filmed.

Well, it's taken me several
trips back to Middle Bass

Island, but I was finally able
to find and successfully catch

the one and only blue bullfrog.

I'm Coyote Peterson.

Be brave.

Stay wild.

We'll see you on
the next adventure.

All right, time to get
these two hoppers back

off into the swamp.

A quick search of
the internet will

reveal that several blue
frogs have shown up in 2020,

including specimens sighted
in Texas, Indiana, Louisiana,

Iowa, and of course, Ohio.

Some say these frogs
are one in a million,

which is probably pretty
accurate, considering

the number of tadpoles
that hatch out and grow

into frogs every season.

Yet while it is rarely witnessed
due to the elusive nature

of most amphibians,
axanthism is relatively

widespread in salamander
and frog populations

that have a limited
gene pool, like frogs

isolated to an island.

For me, the summer of 2020
will always carry with it

the memory of the blue frog.

And if you ever get the chance
to visit Middle Bass Island

and find yourself walking
along the marsh, who knows,

maybe you too will be lucky
enough to catch a glimpse

of the sapphire bullfrog.
