09:41You're probably the happiest because I don't like going to the gym.
09:44But this amount of flight is well within their normal limits.
09:50We caught these guys going like 60 miles an hour down the trails.
09:53Vâng, okay. And then how do you lấy the CO2?
09:57So I put a syringe in here.
09:59Yeah.
10:00Then this valve has been stopping all this up.
10:02Open the valve.
10:04Take the sample.

11:05I can learn how to identify them myself.
11:07This is one of the ones that's really hard to miss.
11:10OK, so it's called trachops.
11:12The common name for this is the fringed-lipped bat.
11:14Because he's got all these little rumps on his chin.
11:17But more common than that, people tend to refer to it as a frog-eating bat.
11:21Because this is notorious, these gigantic ears, he can hear the frogs.
11:25So that one's pretty easy.
11:28But the way this gets complicated is...
11:31Let's look at this one.
11:32So, I can tell right away, by looking at it, this beautiful bat with stripes on its face.
11:37Right.
11:38That this is a Dermanura.
11:39But the problem is that to tell what species it is, I have to look inside its mouth, behind its back molar.
11:47And we're talking about a tooth that's smaller than a grain of sand.
11:51So how many people have this weird skill that you have?
11:54You can look into the tiny molar in the back of its tiny mouth and identify it.
11:59Well, actually, in this group, a lot of people can do this now.
12:01A few years ago, no one could.
12:03The number of bats that get ID'd, studied, and released during Batathon is more than a thousand.
12:10I feel like almost any biological question or evolutionary question you want to ask about mammals, bats are a great model.
12:20Like, how have some bats evolved to live more than 40 years and stay healthy their whole lives?
12:27They not only live for a really long time, they also live really well for that time.
12:32Karen Sears recently made an astonishing discovery about aging in female bats.
12:38Female bats, in a lot of groups, actually maintain their fertility until really, really old ages, which for them is a really, really old age.
12:47Studying tissue samples collected at Batathon revealed that bats' ovaries function perfectly into old age, unlike those of humans or other mammals.
12:58So, as I like to think about it, bats that are essentially the equivalent to an 85-year-old human are still having babies.
13:06It's the normal thing for them to do. They're all doing it.
13:09All the while, while looking like they're 25 years old.
13:12So bats have figured out a way to live forever, stay young, and live that dream.
13:17These findings were really a holy shit moment for us.
13:21Jasmine is hoping her sugar research leads to a similar kind of moment.
13:27I do this really simple test, the glucose tolerance test.
13:31Essentially, you get a dose of sugar, and then at different time points later, you see what happens to that sugar in your blood.
13:39She extracts a tiny drop of blood from the bat's wing before and after feeding, and measures its blood glucose levels.
13:47How your blood sugar is changing over time is a readout for how well your body can handle that sugar.
13:56Jasmine found that nectar and fruit-eating bats are genetically adapted to stay healthy, even with four times the blood glucose level of someone with diabetes.
14:06Baby.
14:07And the bat can go back to the jungle after a nice little treat.
14:13So I like to think that the bats are really happy with the experiments that we get to do together.
14:20Because they'll get some sugar, which they love.
14:23Thank you.
14:25Jerika's bat has finished his workout.
14:31There we go.
14:32This is his reward.
14:33It also makes sure he has lots of energy to get home.
14:34So this is honey water.
14:35So this is going to be very yummy for a little friend.
14:36Gets him hydrated.
14:37Gives him lots of energy.
14:38There we go.
14:39Is that good?
14:40Okay.
14:41You can go now.
14:42There we go.
14:43Goodbye.
14:44Goodbye.

17:15Các bạn có thể tìm kiếm và tìm kiếm và tìm kiếm bản thân thế nào nhé.
17:22Nếu chúng ta tìm kiếm bản thân, chúng ta sẽ có thể tìm kiếm bản thân thế nào nhé.
17:31Chúng tôi đang tìm kiếm bản thân thế nào với Nghezelle và Nina,
17:35Ph.D. bản thân từ New York.
17:39Nghezelle grew up in Belize.
17:41Chí is the country's first bat scientist.
17:52It's great to have Ranger Melvin with us, since we're heading into the remote jungle.
18:01We're deep in the Maya forest, one of Latin America's great wild places.
18:08Nghezelle studies what bats eat, how flexible their diets are,
18:12and how well they adapt, especially as their jungle habitat disappears.
18:17There's spider monkeys up there, and they don't seem happy that we're here.
18:22This will definitely be our backup net, because we don't really want to stress them out too much.
18:27These are squeakers, they will protest the entire time.
18:30The leaf-nosed bats, you can see the nose is shaped like a leaf.
18:34It's always pleasant to catch them, because they're very cute.
18:35Oh, we got a bat.
18:36Oh yeah, we do.
18:37This is one of my target species.
18:38The common name is Little Yellow Shoulder Bat, because the males will have these yellow shoulder patches here.
18:42.
18:43This is one of my target species, the common name is Little Yellow Shoulder Bat, because the males will have these yellow shoulder patches here.
18:55Now we just wait for them to poop.
19:12You use the bat poop to figure out what their diets are?
19:27Mm-hmm.
19:28There's poop, thanks to the Little Yellow Shoulder Bat.
19:33So we extract the DNA from the feces, from the poop, and that DNA contains every single thing that they've eaten.
19:41And so we can compare that with a reference library that has the DNA of all these different plants, like in a library.
19:48What?
19:49So we compare what we got from the poop to what is in the reference library, and it will tell us exactly what they've eaten.
19:55All that from their poop.
19:56Yeah.
19:57You're sifting through poop for DNA.
19:58Exactly.
19:59Checking the Rolodex.
20:00Yeah.
20:02Can I come in?
20:03Yes, you have to lift our door.
20:05Great, thank you.
20:08This little Derminura, which is about smaller than a chicken.
20:11Oh, look at him!
20:12Look at him!
20:13Look at him!
20:14Oh, you got a mosquito there.
20:15Thanks.
20:16He's a very little one.
20:17I always thought that bats would eat things like that, mosquitoes, but this guy eats only fruit?
20:23Well, that's what I'm trying to find out, if they only eat fruit or if they can diversify their diet either by choice or because of necessity.
20:32We need to really understand how at risk they are if we remove the resources they eat.
20:38So, we don't want to re-catch this bat because it's quite a stressful process for the bat.
20:46So, we put some really bright nail polish on its back toes so that if we catch this bat again in the net, we can release it right away.
20:54Oh, that's really clever.
20:56Do you want to do the honors of painting this?
20:57I wouldn't mind.
20:58Okay.
20:59Okay, yeah.
21:00So, just lightly paint the toenails.
21:02I do my hair tones, check my nails.
21:05I'm opening my own salon.
21:08Suddenly, we get a critter alert from Nina just outside the tent.
21:13I saw a snake go off into this area.
21:17Belize has some pretty poisonous snakes, so...
21:20I would say we should move our station away.
21:23Yeah.
21:24Yeah, because it will be very hard to keep track of the snake once it's in all of that brush.
21:29So, the best thing for us to do right now would be to move our entire processing station,
21:33maybe process out the back of the truck now.
21:36Nothing gets in the way of bat research.
21:40Oh, this one's huge!
21:42This is the Jamaican fruit-eating bat.
21:45His teeth look a lot bigger, and he seems to be showing them to you.
21:52They have a very strong bite.
21:53This is the one we really want to wear the leather gloves for.
21:57I am not forgetting this night anytime soon.
22:04We've faced tonight spiders, snakes, a lot of kind of nerve-wracking stuff.
22:10Is it all worth it to you?
22:12I'm from Belize, so this is my home country.
22:16I grew up near all of this nature, and it's a part of me.
22:22I asked Glazel why this research matters to her.
22:25So, at daybreak, she took me to the edge of the forest to explain.
22:29Every year we come back, there's more and more land cleared.
22:32Like, this patch of land was forest just last year.
22:35This was all forest?
22:37It was all forest at one point, just recently.
22:39The jungle is disappearing, replaced by large-scale agriculture.
22:46What does clearing all of this jungle do to the bats?
22:50So, it's destroying a lot of roosting habitat and feeding habitat, for sure.
22:55We're trying to see how adaptable and resilient they are,
22:59because every organism has its limits.
23:02That's why, back at Batathon, there's work to do.
23:12So, once you pull through a little bit out, then you can kind of, like, support them a little bit.
23:17And I'm all in. I'm helping pitch a flight tent.
23:23Andrea?
23:25Do we want to try to attach ropes to the top point?
23:29Andrea Remmel and her mentor, Sharon Swartz, are going to photograph bats in flight, after dark, with super high-speed cameras.
23:38You guys study biomechanics, right?
23:40We do.
23:41Like, the way that bats move as they're flying through the air.
23:43Exactly.
23:44Okay, so where are the cameras going?
23:46We'll mount the cameras around the space on tripods.
23:50Okay.
23:51And then we'll point them into the space so that we're capturing some volume.
23:55We want to get kind of a 3D view of what the bats are doing so that we can reconstruct their movements later after we take the video.
24:02That's the way we can get insight into exactly how wing shape relates to what a bat can do.
24:09How form fits function, we find out right here.
24:12Exactly.
24:13Very cool.
24:14I cannot wait to see the flight tent in action.
24:19But first, I want to meet Brock Fenton, bat expert extraordinaire.
24:27Oh, good to see you.
24:28Hey, Brock.
24:29Glad you made it.
24:30How are you?
24:31I'm fine, and you?
24:32I'm doing well, thanks.
24:33Yeah.
24:34Oh, man, I am excited to get to talk to you.
24:36This guy is the OG bat-a-thon guy.
24:38Like, he started the thing.
24:40This is your book of bats.
24:42Yeah.
24:43And you are like a legend in this field because you are the person who started bat-a-thon.
24:48Yeah.
24:49I don't flim myself into holes in the ground like I used to, but I still have a hell of a good time working with bats.
24:57Brock has devoted his retirement to photographing bats here in Belize and around the world.
25:04Oh, that's a perfect shot.
25:06Yeah.
25:07Vampire bat.
25:08It was probably just shot here.
25:09Look at that big smile.
25:12Teeth at the front there.
25:13Yeah.
25:14So these are the front teeth here that he makes the bite with.
25:18Right.
25:19When you think about the legacy of bat-a-thon.
25:23Yeah.
25:24The impact that it's had.
25:25Yeah.
25:26How many different scientists have come through?
25:27Yeah.
25:28How do you feel about it all?
25:29I mean, I'm not saying I'm responsible for what they've done, but I may have given them a chance to do something that they wouldn't have otherwise done.
25:39Lamini is surrounded by farms owned by Mennonite families.
25:43One family is nice enough to let Caleb and Hugh from the University of Waterloo onto their farm to monitor bats in a cave.
25:50Not really out here.
25:51The moment of truth.
25:53Yep.
25:54Hold on for you.
25:55Oh, yeah.
25:56Awesome.
25:57High five.
25:58Yes.
25:59We got it.
26:00We have something in the range of 80 to 100 bats that are marked here with RFID tags or pit tags.
26:10And we've got an antenna set up at the entrance of the cave just here beside us.
26:14Caleb already activated the antenna during his last trip to Belize a few months ago.
26:19And when you're in Canada, you have no way to check on things.
26:23And so we just showed up and we're seeing that it's worked.
26:25And so that's awesome.
26:27The work is paying off.
26:28It means there's data.
26:29All right.
26:30Let's take a look.
26:31Look at that.
26:32Right up to today.
26:33Right up to today.
26:34Let's see what's here.
26:35Before 17th of April.
26:36Let's see still see there's a bunch of different bats.
26:39The data reveal several species live in this cave, including vampire bats.
26:46Vampire bats are so amazing.
26:47Like they're the bats that run on the ground.
26:49They drink blood and they get all filled up.
26:51And yeah, they're they make long term friendships.
26:53And they're just they're so spectacular.
26:56I love them.
26:58A lot of people think vampire bats are kind of creepy because they feed on the blood of mammals, including livestock.
27:06In Latin America, farmers treat them as pests.
27:10But Jacob and his family have come around after spending time with Caleb at the bat cave.
27:16Every time I'm here, they check in to see which bats are still here and how the bats are doing.
27:20And I think in general, they're just like happy to have them around.
27:23Oh no.
27:24Okay.
27:25It's okay?
27:26Yes.
27:27There we go.
27:28Perfect.
27:29I think maybe putting the harp trap like right here or here.
27:31So that way when they eventually escape, they escape into a trap.
27:35We're going to try to really stitch the cave together.
27:38So the bats have no opportunity besides to fly into our nets if they want to leave the cave tonight.
27:42But we're going to make sure we put stuff on the ground here and put stuff on the sides.
27:45Try to stitch everything right together so the bats just can't really have anywhere else to go.
27:50Otherwise, the vampire bats will crawl on the ground and run out through the holes and jump and fly away.
27:55So they're really smart.
27:56So we're going to outsmart them tonight.
28:15Hey guys.
28:16How's it going?
28:17How are you?
28:18Really well.
28:19Good.
28:20Just got a vampire bat right to the face.
28:22You got hit in the face right here?
28:24Yeah.
28:25So this is a vampire bat.
28:26Wow.
28:27Dude.
28:28This is awesome.
28:29Yeah.
28:30See how he's checking it out?
28:31He's not that scared.
28:32He's looking to see who you are.
28:34So calm.
28:35They're cute.
28:36Amazing, hey?
28:37Yeah.
28:38They're pretty cute.
28:39See how flat the nose is?
28:40Because they're not biting, right?
28:41They're actually putting their face right down and slicing.
28:44And that's how they make the incision.
28:45Right.
28:46If you kind of look at her teeth, see how they're actually turned a little bit to the side?
28:50Yeah.
28:51It's actually more for slicing than for biting.
28:53So these are like little razors.
28:54They're super, super, super sharp, like scalpels.
28:57You said there's multiple species in there?
28:59We have records of seven species in this cave.
29:02Um, why are you guys on that side of the screen?
29:06So as soon as they hit the net, we try to almost like catch them with the net and then
29:10just grab them out really quickly.
29:11Right.
29:12Okay.
29:13Just like that.
29:14And now there's like a creature at that time?
29:17Maybe?
29:18Shh.
29:19Oh my God.
29:22Isn't he awesome?
29:25So what kind of a bat is this?
29:29That's a bat.
29:32That's a golden bat.
29:35They eat lizards.
29:37The big nose leaf and the huge ears.
29:40They're just perfect hunters.
29:42Just up the trail, Hugh gathers details about each bat they catch.
29:59Hey guys.
30:01Can I sit in if I, if I mask up?
30:05For sure.
30:06Okay.
30:07Zero, four, two, four.
30:10We're just processing a bat that we caught a few minutes ago.
30:16That's a vampire bat.
30:21Oh cool.
30:22And so we got like a year's worth of data on them now.
30:25And so it's going to be really cool to be able to understand and shed light on the individuality
30:30of the animal and hopefully in the end some of this information can help us conserve them.
30:36Adult, female, non-reproductive species, tag.
30:41All right.
30:42Bye buddy.
30:43Thanks for hanging out with us.
30:45Okay.
30:49So which bats are hardest to catch would you say?
30:51Vampire bats are the hardest to catch.
30:53They're just so smart and they just figure it out really quickly.
30:57And they can run.
30:58They can run?
30:59They can run?
31:00Yes.
31:01They're the only bats they can.
31:02So there's somebody here I can talk to about this.
31:03Yes.
31:04I can see footage of bats running?
31:05Yes.
31:06On the treadmill.
31:07I'm so excited.
31:10I wanted to see some of them vampire moves.
31:13Hey there.
31:14Uh, Dr. Ken, Dr. Welch.
31:16So I tracked down Ken Welch at the University of Toronto.
31:20I was in the field last night and I met these people that said that there are videos of bats running
31:26and I had to go to the source and find out like what this is all about.
31:29Ken was at Batathon last year.
31:31Running vampires on a treadmill.
31:33What's your day job like?
31:35Well, I'm generally interested in how animals move and in particular what they use to fuel bat movement and exercise.
31:45This video is one of my favorites.
31:48It is just something we noticed the bats doing randomly when we were trying to work with them.
31:52They do this really cool sideways walk.
31:57This is amazing.
32:00We think what they're doing with that sideways motion is maybe circling around their prey animal.
32:06So these guys land on the ground and they sneak up.
32:09So we get, you know, moving around side to side is, yes, sizing up their target.
32:12Being like, what's the safest way to come up and nip the foot and lap up some blood but not get stomped to death by a huge cow.
32:20Wow, so these guys are little ninjas.
32:22That's amazing.
32:23Batathon scientists have even recorded bats swimming.
32:29Did you know they could do that?
32:36From how they move to how they age, it's like bats have superpowers.
32:41What we are finding in the research is that not only do bats have a really long lifespan, they also have a really long health span.
32:49That means that most bats as they age, they don't get cancer, they don't get inflammatory diseases like arthritis, they don't get heart disease.
32:58They don't show that same physiological deterioration that we see in humans.
33:03One of the key things we have to do to study aging bats is actually look in their tissues to see how aging is or is not happening.
33:11Karen collects tissue samples in Belize and analyzes them in her lab at UCLA.
33:17We would love to know what allows bats to live that long so that we could use it as a cheat sheet for humans and figure out how we might be able to make ourselves live longer.
33:26One avenue that my lab has been investigating with this whole bats living forever thing is DNA and the integrity of the DNA.
33:35And what we're finding is that unlike mice, humans, other animals we've looked at, the DNA of the bats stays pretty intact even as they get older.
33:45So it doesn't get a lot of damage to it.
33:48This makes me want to see bats in their home environment.
33:52So I'm tagging along with Elizabeth to another archaeological site.
33:56You're actually walking over a building.
34:00So this is a Mayan building underneath this dirt and trees.
34:06So where I'm taking you now is actually into a tunnel that has been cut into this Mayan ruin.
34:13And the bats have begun using it again.
34:19So they're using it like a cave.
34:21We're going to go in one at a time.
34:23And if we're lucky, the bats are going to be at the back of the cave.
34:27Put on your hard hat and mask up because we want to protect the bats from anything we might bring in there.
34:34Oh, wow. This is snug.
34:52Okay.
34:56Oh.
34:58Trying not to hit the roof.
35:00Okay.
35:02Oh, they're here again.
35:18Oh. Oh.
35:23Oh, my God.
35:25There's so many of them.
35:27It's like these guys have made a whole community.
35:30This is a colony of Nathalus bats.
35:32They're funnel-eared bats.
35:34And they're well-known insectivores.
35:37They've got really, really long, thin legs.
35:39And they're thought to make them really, really good at catching things like spiders.
35:48Elizabeth is a highly respected DNA detective.
35:51She tracks bats and other creatures when humans aren't around, using tools you wouldn't expect.
35:57So this is a very small fan, which acts like a vacuum, and filters air.
36:08And then I have pre-cleaned filters.
36:15And that's actually going to capture any material in the air.
36:18The bat detector is ready for action.
36:23And so as they move back and forth through the air, they're going to shed little tiny bits of themselves.
36:28Dead skin cells, hair follicles.
36:30We call this environmental DNA.
36:32And when they leave that behind in the air, what we're going to do is basically filter it through this device.
36:39So you've left a sampler running inside of there.
36:42What happens next?
36:43Well, we leave it running for about eight hours.
36:45And then we're going to go in and we're going to collect that little filter paper off the top.
36:49And then we're going to amplify and sequence a little tiny, tiny fragment of DNA, which can tell us the different species of bat.
36:56And so we're going to do that over and over again and build up a picture of how this particular tunnel was used and which species came and went.
37:03Right.
37:04While we were sampling them.
37:05So it's kind of like a security camera that figures out who's been in and out.
37:07Yeah, exactly.
37:08And so we get to know what they're doing when we're not there to disturb them.
37:12This groundbreaking work with environmental DNA can be applied on a much larger scale to monitor biodiversity all over the world.
37:21This is absolutely brilliant.
37:26There's action in the flight tent.
37:35Is there a bat in there already?
37:37There's a bat in there already.
37:38Sharon is holding the bat.
37:40And what we're going to do is release the bat.
37:43Right in front of those cameras?
37:44Right in front of the cameras.
37:45Okay.
37:46The cameras are high speed cameras.
37:47You really want to be able to slow down the movements of the bats, which are normally faster than the eye can see.
37:51We need our team members inside the tent to tell us when they're releasing the bat and to tell us when the bat has flown.
37:57And then we'll trigger from out here.
37:59Are you guys ready inside?
38:00We're ready.
38:01Okay.
38:02They're going to yell trigger.
38:03So wait to trigger until they tell us to.
38:06One, two, three.
38:12Trigger.
38:13Nice.
38:14You got it.
38:15There it is.
38:16That looks really good.
38:17Before you release the bat, I saw that you guys were doing something with the bat, right?
38:20What were you doing in there?
38:21We were putting white dots on the bat.
38:23It's really hard to know when you're looking at the video sometimes whether you're looking at like an elbow or a foot or a knee.
38:29And so we put white dots on the parts of the body that we care about.
38:32We really want to characterize how that wing shape is changing during flight.
38:35Right.
38:38So it sounds like the team inside is ready to fly another bat.
38:41Do you want to go in and help them out?
38:43Yes.
38:44Can I?
38:45Okay.
38:46Welcome, Anthony.
38:47Can you close that zipper?
38:48Sure.
38:49We don't want the bat to leave this flight fence.
38:54This is Mr. Artivius Luteratus, the greater fruit-eating bat.
38:59And this is one of the larger bats that we have here.
39:02We're going to pull the wing out so you can see the fingers.
39:06Right.
39:07It's a dot, dot, dot, dot.
39:09One on the elbow there.
39:10Or is that the shoulder?
39:11No, that's the elbow.
39:12You're exactly right.
39:13Elbow, okay.
39:14This is a great mammal hand.
39:15You know, this animal has almost every joint in its wing that you have in your hand.
39:20Mm-hmm.
39:21That's what makes them such incredible flyers.
39:25So, um, trigger team, are you guys ready to go for another flight?
39:30I'm ready out here.
39:31Okay.
39:32So, this is a pretty chompy bat.
39:34It's got really big teeth and powerful jaws.
39:37Three, two, one.
39:42Trick.
39:43Trigger.
39:44Oh.
39:45Well done.
39:46Did I say it right?
39:47You did it.
39:48I just said something.
39:49Did we get anything?
39:50Let's see.
39:51We're going to review.
39:52This is my first time as a bat scientist.
39:53That's beautiful.
39:54It was?
39:55Yay!
39:56Darren has studied bat wings for 35 years, revealing how their flight evolved separately
40:01from birds.
40:03Bird wings are stiff and feathered.
40:05Bat wings are flexible membranes, stretched over long jointed arm and hand bones with tiny
40:11muscles throughout.
40:13This lets bats constantly reshape their wings for aerobatic maneuvers.
40:18It might also explain why they hang upside down to rest.
40:23I mean, what would you do if your arms, legs, and butt were all connected by a giant oversized
40:29wing?
40:30Well, so it turns out that being tall is a real advantage when you're trying to catch
40:35that.
40:36Oh, so I'm catching him too.
40:37Okay.
40:38I don't want to hurt him.
40:39Yeah.
40:40I think if you just try to get him in the middle of the net, try not to bonk him on the
40:42head.
40:43Okay.
40:44Here we go.
40:45Three, two, one.
40:46Wow.
40:47Wow.
40:48Got him.
40:49Wow.
40:50Awesome.
40:51So we'll bring him back to exactly the area where he was netted so that he'll be really
40:59close to his home roost.
41:00Mm, okay, right.
41:01It'll be someplace that he knows really well.
41:06Great job.
41:08If there was a message that you guys could send out to the world about why they are
41:17maybe could love bats as much as you guys do, what would it be?
41:21People like whales and dolphins, and those are weird, slippery things that live in the
41:24sea.
41:25And all of the things we like about whales and dolphins is that they have families, they
41:29live for a long time, they're really intelligent.
41:31Those are all things that we know about bats.
41:32And as we learn more about bats, we find that they're more and more like whales and dolphins.
41:37And us.
41:38And us.
41:39And us.
41:40They're more like us than I think most animals are.
41:44And us.
41:45My week at bat-a-thon has, ahem, flown by.
41:49Time for one last glimpse of my new furry friends.
41:54And to say goodbye to an awesome group of scientists.
41:58Thanks.
41:59Everybody say lamb and eye.
42:01Lamb and eye.
42:02You don't have to say that, that's what that is.
42:08It's been great having you here.
42:09Well, thank you.
42:10It's been fun teaching you about the bats.
42:12I've really enjoyed learning about this.
42:13I feel like I've got a couple names down.
42:15There's, um, Artibius Intermedius.
42:17Yes.
42:18Mm-hmm.
42:19There's, um, Glosophagus.
42:20Glosophaga.
42:21Glosineterbat.
42:22There's Desdemona is a character from Shakespeare.
42:26Desmodus.
42:27Desmodus.
42:28The vampire bat.
42:29Right.
42:30That's pretty good when you've just learned these names recently.
42:32I'm not doing too bad.
42:33What was the most interesting thing you learned here?
42:35Ah, man.
42:36Oh.
42:37That's tough.
42:38You know, 1,500 species is massive.
42:40I thought there were, like, seven.
42:41Yeah.
42:42So that's a big surprise for me.
42:43And, um, and, you know, they're so unique, but there's such a range.
42:46You know, some are really cute and adorable and tiny, like the fruit bats.
42:49Yeah.
42:50And some are, um, more unique facially.
42:52I think that's what gets me coming back all the time.
42:54Because they're, they're all bats, but they're also so different.
42:57I would say that the biggest thing I learned was that a lot of people are kind of afraid of them.
43:01They're kind of nervous about them.
43:03But once you get up close to them, like, and you see their little hearts beating and you see that the little...
43:07The fur and the eyes that they watch you.
43:09Yeah.
43:10Like, they're, it's so much easier to empathize and connect with them than I thought.
43:13Just getting, I didn't expect how getting that close to them would affect me.
43:16It was, it was really lovely.
43:18Yeah.
43:19Say, Batty!
43:20Batty!
43:21Awesome.
43:22Well, thank you guys again from the bottom of my heart.
43:24It's been great.
43:25You guys have been awesome Bat Ambassadors.
43:27It's been a blast.
43:28It's been a blast.
43:29It's been a blast.
43:31I'm going to end it up here.
43:32I'm going to end it up here.
43:33I'm going to take care of you guys again from coming down and there.
