00:01              雲が掛かった
- It's a slightly overcast day here in Kentucky,
00:04
which is the perfect conditions
00:06
if you're searching for salamanders.
00:08
In the United States, there are 186 different species.
00:11
And the good news for us is that here in the southeast,
00:13
102 of those salamanders can be found.
00:16
So what we're gonna do is as a team,
00:18
flip multiple rocks and see how many
00:20
of these slimy amphibians we can come across.
00:22
We're gonna search all along this cliff base, with any luck,
00:25
this is gonna be one successful salamander scavenger hunt.
00:29
All right, guys, let's start flipping.
00:31
Oh, got a salamander, guys.
00:33
(film reeling)
00:35
(upbeat music)
00:42
(animal roars)
00:47
Wow, look at that.
00:48
That is the long tailed-salamander right there.
00:51
Now the easiest way to identify this species
00:53
is the length of the tail,
00:55
hence the name long-tailed salamander.
00:57
They're also orange in coloration
00:59
with all this black speckling.
01:01
And what's cool is these are closely related
01:03
to the cave salamanders that we have featured before.
01:06
Now with each salamander that we come across today,
01:09
we're gonna try to get a really cool macro B-roll shot.
01:13
You can't truly appreciate the beauty
01:15
and magnificence of a salamander
01:17
unless you can be right there next to it.
01:19
What's cool is that this is a lungless salamander species,
01:23
which means it's absorbing all of its oxygen
01:25
through its skin.
01:27
I like all salamander species,
01:28
the long-tailed is a voracious predator.
01:31
They will eat pretty much anything that they come across.
01:33
It fits in that mouth, it is fair game.
01:36
Okay, that's our first salamander of the day.
01:39
and it's very important to place the amphibians
01:41
right back where you found them.
01:44
Away you go.
01:45
All right, let's see if we can find some more salamanders.
01:48
(upbeat music)
01:53
Look at this, look at this, look at this.
01:54
It's a fissure of salamander.
01:56
- [Mario] Oh man, that's a salamander.
01:58
- That's salamander?
01:59
- [Mario] Pretty sure.
02:00
Just make sure it doesn't go into borough.
02:01
- Yeah, yeah, yeah. Hold on a second.
02:02
If I could get my hand down underneath here.
02:04
Yes, yes, that's a red salamander.
02:06
- [Mario] No, it's a mud, that's a mud.
02:07
- [Tim] Grab him, don't let him go.
02:09
- [Mario] Yeah, that's a nice one.
02:11
- Oh, got him, got him.
02:12
Oh, that's a rare one?
02:13
- [Mario] That's what a lot of people would love to see.
02:15
- Wow, Look at that!
02:17
A mud salamander.
02:19
Very robust body.
02:21
I thought it was a red salamander just with seeing the tail.
02:24
Whoa, that is good size too.
02:27
Like the name suggests, they will bury down
02:29
in the mud very, very quickly.
02:31
This is a fossorial species.
02:33
They love staying in that moist muddy environment
02:36
and not one that is really easy to come across.
02:39
Now, one way to tell the difference
02:40
between a mud salamander and red salamander
02:43
is that the red salamander has a goldish eye
02:46
while the mud salamander has a muddy brown eye.
02:50
What's cool about the mud salamander
02:51
is it has a very robust body structure.
02:53
They do get a little bit bigger than this,
02:55
but this would be considered a full-sized adult.
02:59
Okay, our second salamander
03:01
is officially caught and recorded.
03:03
Let's keep searching.
03:05
We're doing pretty good so far.
03:06
We're moving away from that rock base,
03:08
moving deeper into a forested area
03:10
where Tim says we will find some of our next species.
03:13
This pine forest, despite looking dry,
03:16
actually retains quite a bit of moisture.
03:19
So any logs or rocks that are flat to the ground,
03:22
like this one here, may have salamanders under them.
03:34
I see worms. That's a really good sign.
03:37
Where are you find worms,
03:37
you're likely to find the salamanders.
03:41
I just heard Tim call off in the distance.
03:43
He's got another salamander.
03:44
This will be our third one of the day.
03:47
Oh, look at that.
03:49
Yes!
03:50
Is that a slimy salamander?
03:51
- It is. - Wow!
03:53
Good find, Tim.
03:57
I got him.
03:59
Whoa, whoa, he's quick.
04:00
That, whoa, stay, is a slimy salamander.
04:06
Now they're called slimy salamanders
04:08
because as soon as they feel
04:09
as if a predator is threatening their existence,
04:12
they will secrete a very sticky slime,
04:15
so much so that it will gum up the mouth of anything
04:18
that is trying to eat it,
04:18
in some instances, will even choke and kill its attacker.
04:22
Easy to identify given it's speckled patterning.
04:26
Whoa, it is fast!
04:28
And it bounced onto there.
04:29
Actually, Tim, get out
04:30
that little lock container real quick.
04:32
Let's see if we can get this guy to calm down.
04:34
Trying to just run up and in to my jacket here.
04:37
I see you're trying to stay hidden.
04:38
Oh yeah, I can already feel that it is super sticky.
04:42
Wow! All right, let's get it moist here.
04:45
Here you go, buddy. Whoa, that is cool.
04:47
Look at how fast it's capable of moving.
04:50
Now, whenever handling any salamander species,
04:53
it's important to carry a small little plastic container
04:56
with you with a small amount of water.
04:58
What you don't wanna do is drive the salamander out.
05:00
Remember, amphibians secrete a mucus from their skin
05:02
to keep themselves moist,
05:04
and the less of that moisture you can suck
05:06
into your own skin, the better it is for the creature.
05:10
And we're actually getting the B-roll shot.
05:12
We wanna be as still as we possibly can.
05:14
No sudden movements.
05:16
Salamanders bodies are incredibly durable.
05:19
And many of the salamander species
05:20
in this area are capable of actually dropping their tails,
05:23
just like a lizard,
05:24
so we have to be very careful when we handle them.
05:26
You never wanna pick up a salamander by its tail.
05:30
Now the slimy salamander is one
05:31
of the most common salamander species here
05:33
in the Southeastern United States.
05:35
People often miss identify them for spotted salamanders.
05:38
Both species are black,
05:39
but the spotted is more robust
05:41
and has very distinct, large yellow spots.
05:44
These spots are more sparsely spread
05:45
throughout the salamander's body
05:47
and you can see they're almost whitish gold in coloration.
05:51
Okay, we're gonna place the salamander right back
05:54
under the log where we found it,
05:56
but good salamander etiquette is
05:59
to always place the log back exactly the way you found it.
06:03
What you don't wanna do
06:04
is accidentally squish the salamander.
06:06
So getting it right back into its spot, like that,
06:09
then the salamander can scurry back up underneath
06:12
and it will be totally safe without being squished.
06:16
There you go, little guy.
06:20
There you have it,
06:21
the slimy salamander our third of the day.
06:25
Okay, so we've made our way down this ravine
06:29
and we have found some pristine creek salamander habitat.
06:33
Look at this.
06:35
All of that running water
06:37
and all those rocks are super flippable.
06:40
Whoo!
06:41
Just when I thought we had run out of places search,
06:43
we find this environment.
06:46
This is super perfect.
06:49
All right, Tim flipped another salamander.
06:51
I guess it's a two-lined.
06:52
- I got a little guy. - Oh, a tiny one.
06:54
Still counts, that's a new species.
06:57
Oh, it's got a little nub tail.
06:59
There's a perfect example of a salamander that lost its tail
07:02
and is starting to regrow a new one.
07:04
It is definitely one of the more common
07:06
stream salamander species.
07:08
Beautiful, the way to easily identify them is the two lines
07:12
that run down the length of the body.
07:14
And they usually spill all the way out onto the tail,
07:16
but this guy doesn't have a tail.
07:18
That is our fourth species right there.
07:20
And these salamanders specialize
07:22
in eating small worms and crayfish larva.
07:26
It's definitely the smallest salamander
07:27
we've come across today,
07:29
arguably, the most common as well.
07:32
If you're out flipping rocks in a stream
07:34
in the Eastern United States there's a good chance
07:36
you're gonna flip up a two-lined salamander.
07:44
Salamander, right here.
07:45
Tim, got a salamander!
07:46
(dramatic music)
07:49
I don't know what it is, it's all black.
07:52
Blackish gray?
07:57
- From the looks of it and the speckling on the side,
07:59
it looks like a northern dusky salamander.
08:01
Careful, they're real fast. - Okay. All right, cool.
08:05
All right, Mario wanna get out
08:06
the B-roll camera? - Yup.
08:07
- Actually, this little ledge right here
08:08
might make the perfect spot to get those B-roll moments.
08:11
All right, how about that?
08:12
Our fifth salamander of the day, the northern dusky.
08:15
Now this salamander species has an incredible sense of smell
08:19
and like all the plethodont species,
08:21
they have these nasal grooves just behind the nostrils
08:24
called nasal labial grooves, incredible sense of smell.
08:28
These are slightly nomadic predators, very opportunistic,
08:32
but this is a salamander species
08:33
that will actually feast upon smaller salamanders.
08:37
Very sharp teeth, not something you wanna run into,
08:39
but a creature of this size is definitely way too small
08:42
to bite a human.
08:42
How's the shots looking? - Good.
08:45
- Pretty good? - Uh-huh.
08:46
- Well, There you have it,
08:47
our fifth salamander species of the day.
08:49
All right, let's place this one back on its rock
08:51
and keep on moving.
08:55
Okay, we are not moving out of the creek environment
08:58
up this rather steep hill
09:00
where we'll try to find our next spot.
09:02
Although, it does look like the sun is fully overhead.
09:05
Not real sure that the conditions are gonna continue
09:08
to be in our favor.
09:10
Those logs look good. Let's see.
09:12
Eenie, meenie, miney, mo.
09:14
Catch a tiger by its toe.
09:16
If it hollers, let it go.
09:18
Eenie, meenie, miney, mo.
09:20
All right, we'll go for this one first.
09:22
Here we go.
09:25
Could this be our sixth salamander of the day?
09:28
(suspenseful music)
09:35
(speaking faintly)
09:38
Right here, salamander!
09:39
Oh, Mario, Mario, Mario!
09:40
What'd you got? - Red salamander.
09:42
- Are you sure? - Yep.
09:44
Come on, buddy. Look at that.
09:47
Wow!
09:49
Very similar looking to the mud salamander,
09:52
but many more spots
09:54
and it actually has a gold iris within its eye.
09:57
That's one of the easiest ways to tell this species
10:00
from the mud salamander.
10:02
Oh, that is a big one, very robust body structure.
10:05
And what's unique about this salamander
10:06
is it also has a very short tail
10:08
as compared to the mud salamander.
10:10
This salamander is not nearly
10:12
as vibrant as the mud salamander,
10:14
and the spotting pattern
10:15
that runs over the length of the body is much more dense.
10:19
Well, the sun's directly overhead,
10:20
the temperatures are beginning to climb,
10:22
which means our odds of finding salamanders
10:24
are not nearly as good as they were this morning.
10:27
But I say we did pretty good.
10:28
Several species in just a few hours.
10:30
So hopefully you guys enjoyed
10:31
this salamander scavenger hunt.
10:33
I'm Coyote Peterson.
