I'm Josh, and there's Chuck and Jerry's here too,
and it's short stuff.
Cute, cute little bug edition.
That's right.
We're talking about pill bugs, or potato bugs, or wood lice.
What?
Or for our English friends.
Chicky pigs, penny sows, or cheesy bugs?
I have no idea what
we're talking about, Chuck. We're talking about here in the
American South, at least, Rolly Polies. Oh, Rolly Polies. Is
that what you called them? Yeah, that's what I always called
them. It's funny, I was trying to look up a map of their range
in the United States. And all I could find was dialect maps
of what people called them around the United States. So I have no idea what their actual
range is, but I can tell you in the South, everybody calls them roly polies.
Well, if they call them something, that probably means they have them, right?
Yeah. For sure. I mean, we have them. I've seen them before with my own two eyes.
That kind of shows you the range. I got, oh, if it's named.
Boy, Chuck, I think I'm getting dumber by the month.
Oh, but you never know.
They might be like, hey, they don't exist in Washington State, but we still call them grungers.
Yeah, we like to say the word chiggy pigs.
But we're talking about the little round, well, not round, round if they're threatened, we'll get to that. But the little thing that you probably think is an insect that looks like a little prawn or an armadillo with legs.
And in fact, the scientific name is armadillium, armadillidium vulgarae.
Very nice.
Geez.
That's why people shortened it to chiggy pigs.
Yeah.
And that's a roly poly.
Yeah.
And actually, strangely enough, even though, like I said,
I've seen them with my own two eyes in Georgia,
they are from the Mediterranean initially.
But they spread all over the world.
You can find them all over the place
because they were basically carried over
through the plant trade, the international plant trade.
That's right. You want some plants? They're gonna come with some, well, they're gonna come with
insects, but I keep saying insect. They're not insects. Should we go ahead and spoil what these
things are? Yeah, totally. It's one of the facts of the short stuff. You take it. Oh, thank you. So they're not insects, Chuck. They're not mammals.
They're not birds.
They're crustaceans.
Yeah, I mentioned shrimp.
Cousins to crabs and lobsters and shrimp, yeah.
That's right.
And there are 12 species in the United States alone.
It says northern and central parts of the country,
but maybe they don't dwell in like the deep deserts,
who knows. But I know I see them all over the place here. They're the only crustacean that has
adapted to live entirely on land, and they breathe through gills, which is remarkable.
Yeah. So the fact that they have adapted to live on land, the only crustaceans that did,
that's another fact of the podcast. Just amazing stuff, right?
But technically it's a sub fact of the fact
that they're crustaceans, I guess.
Another fact of the podcast though is there's a word
for them turning into roly-poly, it's a tight little ball,
which, well, I guess marine biologists
have determined was an evolutionary response to predators or to keep their gills
moist. They curl up in a little ball, hence the name roly-poly, but there's a term for
that. And I think you should tell everybody what that is.
All right. It is conglobation.
Yeah. Now, had I said it, I would have said conglobulation, but that's not correct.
It's the better way to say it, but it's just not right.
Yeah. You love adding things.
Conglobation.
Fancy enough a word. That's Josh Clark, the Josh Clark way.
For sure.
So there's a lot of remarkable things here. We're gonna check off a couple of them and then take a break,
but one of them is they do not urinate.
They have a very high tolerance for ammonia.
So they don't urinate.
They excrete waste through the shells.
They eat all kinds of things in the garden,
but one thing that they eat is their own poo poo,
which is a practice called self car profigy.
Keprophogy.
Self-keprophogy.
Keprophogy.
Yeah, after an hour in there, didn't I?
Yeah.
They're poop eaters.
Yeah, they eat their own poop.
And it's like, yeah, it's gross, but it also makes sense because you don't necessarily
get all the nutrients out of your poop.
So if you eat your poop, you have another shot at extracting more
of the nutrients that were left over. Yeah, like you miss something. Try again. Yeah.
There's a piece of shrimp in there, ironically. They can drink from their mouth or they can
drink from their hind end. They have a little tube shaped structure in the back. And so it
doesn't matter if the parties in the front
or in the rear, they can still get their drink on.
That's funny.
The joke I came up with is that they can use them both
at the same time and share a milkshake with themself.
Oh, that's even better.
No, I think they're equally good.
Well, I just thought of mine.
That's not as good.
Well, mine's written down.
So technically yours is better because it's off the cup.
Well, you just made yours up too.
You just wrote it down.
True that. Unless did you workshop it yours up too. You just wrote it down. True that.
Unless did you workshop it over a couple of days? Yeah. You'd be so tired of hearing that joke.
Which one, you mean? Shut up. Should I say milkshake or shake?
How about one more factoid and then we'll take a break. Okay, yeah, they're crustaceans, but they also have a marsupial pouch, essentially.
Yeah, those mamas carry their little eggs around
for two to three months in their marsupium.
They hatch, and then sometimes even those little youngins
will go back in that pouch and say,
mama, I still wanna stick around for a little while
until I'm ready.
Hey, mama.
Like Elvis.
Okay, now it's time for a break because
the facts are coming so fast and hard that I'm crying tears out of my eyes right now, joy. All
right we'll be right back.

by multiple Latin stars, including J Balvin, Bad Bunny, Osuna, Antimotasha.
Explore the evolution of this dynamic genre and what makes it resonate globally.
How you consume Pregatong, how you share and distribute Pregatong, those are all an important
part of the story.
It's the way that the people are experiencing Pregatong along with the musicians.
Listen to El Fló as part of the Mike Ultura podcast network, available on the iHeart radio
app, Apple podcasts, or wherever you get your podcasts.
All right, we're back with some more amazing facts.
These little guys are arthropods, so they're gonna
molt, and if you ever see a little cheesy wog, what do they call them in England?
Cheesy wig? Chicky pigs? Chicky pigs? Or cheesy bugs, yeah, you're close. Cheesy bug?
And if you find one that's like, hey, that thing looks funny, looks like it's got
half a shell, it's because their shells are in two pieces, there's a front and a
back, they drop that back one first first so you may see one missing its back
And you just got to be just leave that little little fellow alone. Yeah, he's porcupigging it. Yeah
That's exactly
There's some other things you should know about them another reason to leave them alone and even to invite them into your garden as you'll see
They don't sting, they don't bite,
they don't carry diseases,
and not only do they not mess up your plants,
they actually help your garden grow even better,
because these guys are soil maniacs.
Yeah, they're champions of your composting efforts,
because they get in there, they have
what's called a detritivorous diet.
Is that how you would say it?
Well I would say detritivorous diet.
That it means they basically take anything that's from a decomposting plant or if there's
a dead animal or other poop, they can absorb all those nutrients,
poop it out themselves,
and they're just little composting machines,
which is pretty amazing.
But to me, one of the most amazing facts
is that they're into heavy metal.
Yeah, like big time, like-
Crocus.
Sabbath.
Dio.
Docken. Maiden White Lion Oh boo
God, what if we just named metal bands for the next six
minutes?
Quiet Riot.
Oh man. Bend your head. That's hair metal. It's still metal.
All right. It's the most metal of hair metal I would say
quiet Riot is at least some of their songs. Yeah, metal. All right. It's the most metal of hair metal, I would say quite right is at
least some of their songs. Yeah, I like quite right. Yeah, they're great. That's good stuff.
What about Testament, the other Christian metal band? I don't think I knew about them. Yeah,
there's Testament. That sounds familiar though. I'm pretty sure they were Christian. They talked
a lot about Christianity. Did they rock hard for Jesus? Oh, dude, pretty sure they were Christian. They talked a lot about Christianity
Did they rock hard for Jesus? Oh, dude, they rocked super hard. They were like the kind where you could be like
I'm not at all religious, but I still like testament. Yeah, kind of like my boys and striper Queen's Reich
They were weird, but they were still metal
All right, so they love heavy metal. They love all those bands except for white lion
All right, so they love heavy metal. They love all those bands, except for White Lion.
But what we really mean is they have a very unique ability
to eat zinc and lead and copper
and any other kind of like awful heavy metal
that might be out in the wild
and crystallize it in their bodies
and thrive in these heavily polluted awful areas.
They crystallize it in their guts
and can remediate it essentially.
Yeah, if you crystallize something,
you're essentially encasing it in glass
and it becomes inert as far as I can tell.
So I don't know if they poop it out afterward
and it's inert because it's been encased,
but whatever they're doing there,
they're, yeah, they're doing there,
they're remediating essentially super fun sites
of heavy metals.
If you just got a handful of them and said,
I'll see you in 50 years.
Yeah, absolutely.
So like you mentioned, they're great for your garden.
They may, I mean, the damage that they might be doing
is pretty minimal.
They might try and drink and get moisture from your plants and things, but they're not
the kind of land crustacean that's just gonna eat through all of your garden vegetables.
Right.
There are no land crabs.
No, not a land crab at all.
You got anything else about roly pollies?
No, this is short and sweet.
Well, I'm glad that we did a pretty good PSA
to let everybody know, leave the Roly Polys alone.
And short stuff is out.
