  • Hey it's me Destin, welcome back to Smarter Every Day.

  • Simple question here.

  • Do you know, like really know,

  • what a kangaroo pouch looks like?

  • Several years ago I was invited to Australia to help promote National Science Week

  • with my friend Chris who has a website called Science Alert.

  • As far as I knew kangaroo pouches look like,

  • well you know, your jean pocket, like a little flap.

  • We've all seen cartoons of kangaroos but is that what a kangaroo pouch looks like?

  • My wife and I flew over to visit Chris and right off the bat this happened.

  • - There's a kangaroo!

  • Look there he goes.

  • - He's gonna come our way.

  • (Destin) Oh man.

  • - He's gonna cut right across in front of us.

  • - Oh my goodness!

  • Seriously!

  • - You will see some roadkill, and now you'll know why.

  • (Destin) Not really smart, are they.

  • Man that is bizarre.

  • - On cue as demanded.

  • [laughs]

  • I called that in. I said I want a roo at the Chinese Embassy.

  • (Destin) Oh yeah that is the Chinese..

  • - 4:23.. Be there.

  • [laughter]

  • - And yeah that's pretty cool but it didn't feel like a wild kangaroo

  • so I asked Chris to take us to a local area called the Tidbinbilla Nature Preserve

  • where hundreds of kangaroos are known to hang out.

  • You rolling?

  • - Rolling.

  • - OK we spent all that time out in the wilderness and then we come back to grill some sausage and they're coming up to us,

  • so obviously we have to see if we can find the pouch.

  • - I'm not sticking my hand in there.

  • - Just try it.

  • - Did you see his nails? Like this..

  • - But it's.. They're on the ground. Look, go for it.

  • Look, you have a degree in biology and I don't.

  • - I think he does have a small one. I think.

  • - There you go.

  • - You want me to give him some more nibbles?

  • You're good, you're good.

  • [laughs]

  • Today we learn kangaroos do not have pouches.

  • Alright, I'm gonna sit this there...

  • Alright, let me.. I'm just gonna reach under here.

  • No no no, it's cool, it's cool dude.

  • No need to poop, no need to poop.

  • Here, I'm just feeling for your pouch

  • that's all we're doing here.

  • I'm very gentle.

  • I'm trying to get the pouch. I haven't..

  • - That ain't the pouch buddy.

  • - [laughs]

  • I feel ribs.

  • What've we got.

  • Bro, you're awesome.

  • I can't find a pouch. [laughs]

  • OK this is a..

  • Do males have pouches?

  • - I don't know.

  • - [laughs]

  • This is my logic.

  • Females have nipples and feed babies.

  • Female kangaroos have pouches and hold joeys.

  • I have nipples and I don't feed babies.

  • Therefore it's possible that male kangaroos have pouches

  • but don't hold joeys.

  • Even though I was touching this kangaroo directly

  • the geometry felt a little weird.

  • So the next day we're driving to Kangaroo Valley

  • I have a genius plan.

  • OK we're randomly walking up to a house and we're gonna ask about kangaroos.

  • And what was your name again?

  • - Angela.

  • - Angela, so Alan has told us something that's amazing about the kangaroo.

  • What is it Alan?

  • - Kangaroo is an amazing animal, it's unusual,

  • it's unique in the world, it's a furred animal,

  • four-legged and it's the only animal in the world that has its testicles in front of its penis.

  • - I guess that explains why the geometry felt weird.

  • If you know that, you have to know this.

  • We were trying to.. I had a kangaroo,

  • and he let me pat his belly.

  • I couldn't find a pouch.

  • Do male kangaroos have pouches?

  • - No they don't have a pouch.

  • - They don't. Only the females?

  • - Only the females.

  • - So.. How.. Are they born with the pouch?

  • - They're born with a pouch, yes.

  • - Really.

  • - Yeah they are. Well.. They develop a pouch.

  • They're born, they're minute, they're smaller than your little finger

  • and they're born through the vagina.

  • And then they climb up the front of the kangaroo on the fur.

  • She licks a track, they climb up and they go into the pouch.

  • - Really.

  • - Sometimes she'll have two or three.

  • Then he attaches to the nipple.

  • - To the teat.

  • - Yeah he grows on it.

  • And he can't be pulled off without tearing his mouth out

  • for about.. Oh I think it's around about two months.

  • And then he starts to develop fur,

  • and he becomes detached from the nipple.

  • And when he's about four months old he starts to pop his head out,

  • look around and so on.

  • - We went to a place called Josephine's Gallery & Kangaroo Orphanage,

  • which I thought was really cool

  • because Josephine and her husband Terry raise these kangaroos

  • that come to them from all over an area the size of Texas.

  • They have to basically recreate what it's like in a womb

  • in order to nurse these small kangaroos up to maturity.

  • I learned from Terry, the husband, that the female kangaroo has four

  • nipples on the inside of the pouch and even he wasn't sure if male

  • kangaroos had nipples or not.

  • - Little wobbly... There you go.

  • - So are all of yours females?

  • - Got all females at the moment, yep.

  • (Destin) Where's the pouch you said?

  • - It's there.

  • - Really.

  • - Tuft of fur there.

  • - Wow.

  • - Yes it's quite compact.

  • [background conversation]

  • - What you doing babe?

  • Oh you ready to go back to bed are you?

  • You looking for your pouch already?

  • Oh yes yes yes I know I know. Hohoho. In you go.

  • [laughter]

  • Every time we feed her she has that little bit of time down

  • and that'll just slowly increase as she gets a bit older.

  • So she's only been hopping around just over a week

  • she's been learning to stand, so she's doing pretty good aren't ya babe. Eh?

  • - So that's cute and all but we still haven't looked inside a kangaroo pouch.

  • So we went back to Sydney, we called up the big guns, Taronga Zoo.

  • Across the bay in Sydney, it's awesome.

  • We took a ferry, all kinds of Australian wildlife,

  • you take a cable car up to the top, overlooking the zoo

  • and then we schedule one-on-one time with Sam,

  • the zookeeper. Is that the proper term?

  • - That's right.

  • - Alright and this is Penny right?

  • - Yeah.

  • - And so you said..

  • Stay there Penny.

  • We're gonna go..

  • Where's your pouch?

  • Oop, there it is.

  • There it is. Oop!

  • Little present there.

  • Can you hold the pouch open with one hand?

  • - Sure. Let me just get some more sultanas.

  • - Sultanas are raisins right?

  • - Yeah.

  • - Alright.

  • That's the pouch.

  • Wow. Let me see if I can.

  • So its.. That's why I couldn't find it, it was very small.

  • So you can.. Man that's amazing.

  • So back in there, at the very back of it,

  • I can see. I probably can't see it on the uh..

  • Yeah look at that.

  • There's white and black spots in the back.

  • Thank you girl, I'm sorry.

  • - Get it?

  • - Yeah. So it's really small and it stretches out.

  • I thought it was.. As an American I always had the misconception

  • that it was like a pocket right here on the belly

  • because that's the way it is on cartoons.

  • Thank you for showing me that.

  • - No problem

  • - Bam! We just learned something.

  • I always thought kangaroo pouches were kind of like pockets on your pants.

  • They're not. They're way cooler than that.

  • Before I show you footage of my family feeding giraffes at Taronga Zoo

  • I want to mention the sponsor.

  • They made my quest for marsupial orifices possible.

  • Audible.com sponsors Smarter Every Day.

  • Just so you know I'm not lying here, I listen to all kinds of audio books.

  • That's my library.

  • You can go to audible.com/smarter and get any book you want for free.

  • audible.com/smarter, that easy.

  • You can get Smarter Every Day by listening to audio books.

  • I do it on my way to work.

  • Pretty cool way to get smarter.

  • Anyway, I listened to Ender's Game by Orson Scott Card

  • as we flew over the Pacific Ocean to Australia.

  • Really good book, but you can get whatever you want.

  • audible.com/smarter.

  • One more thing.

  • Um, thanks.

  • Thanks for watching a video about me running around Australia

  • trying to find a specific marsupial orifice.

  • That's really weird, and you're watching this whole video, so thank you.

  • Please consider subscribing if that added value to your life.

  • If not, have fun watching my family feed giraffes carrots.

  • I'm Destin, you're getting Smarter Every Day.

  • Have a good one.

  • What's the term?

  • - Prehensile.

  • - Prehensile, meaning they can direct it.

  • Prehensile.. wow.

  • - So it's very hand-like we say.

  • - Oh can we.. I want to hold and see if they can pull against me. Is that possible

  • or is that a bad thing to do?

  • Of course she gave me a small carrot to do it. [laugh]

  • - .. saliva you're getting there.

  • - Oh my goodness.

  • - I tried it.

  • - Yeah.

Hey it's me Destin, welcome back to Smarter Every Day.
