Axel Little, however, is a perpetual teenager, and it's achieved every teenager's dream of removing the need for grown ups. Ah, a bit like me. It lives his whole life in a state of arrested development, retain his gills and fully aquatic existence back to New York to find out more from Dr Darrell Frost, your mole salamander and you transform. It means you become air breathing. It means you're running around on the surface. And if if outside of the pond or lake is too dry to survive as an adult, it's a bad thing to transform because it's a death sentence when there's no going back to that, that's right. That by modality, to be able to be one of the other and optimize on the habitat is best to be in is a good thing, and it's It's done well for for the mole. Salamanders very deep in the genetic code, accidental still retain the ability to fully transform into adults on this is where it gets really weird because very occasionally this actually happens. I'm backing Mexico City in search of a boy. Lacks a lot around late. Such a milk. Oh, there's evidence of accelerators everywhere. But we've thrown hundreds of nets throughout the canals here and found very little but in face of fish species. Oh, my goodness. May look at this awful. Now I swear on my favorite pair of binoculars that this is our last day of hunting. Fisherman Roberto has got us into the Last Chance Saloon, a rowing course constructed on the edge of the canal system for the 1968 Olympic Games on dhe. Just seen my first wild axel bottle. I definitely just saw attacks a little. Yeah, just nothing Down right away. No doubt about it. Absolutely. Just definitely, definitely definitely is whether no, it's in the net. This is the question. I definitely just saw an axle. It'll rise unmistakable. I mean, I saw it. I saw its tail. I saw its head. I saw it take the air. Just happened to be I was What's the word Middle distancing? I was screened, savoring. I was just blankly staring the green thinking ways, the hope and then suddenly boom right in the middle of my vision. Question is, did the catch it? Please, Please, please let us let that be in the net. Very muddy. Good going. Hey, stop! You start. Is it in it? Yes. Way Haven't X a little way? Haven't accidental a rail. Life boiled accident. Awful. Oh, man, how do we get it out? Just about that. I can't believe that it always makes more accident. Let's put it well, It's a big one as well. Oh! Oh, I would kiss you, But you covered in golden eyes. It might be covered with filth, but it's love at first sight. I've got a nice little boiled. Excellent kills. It's absolutely astounding. Who would have thought it, Eh? We have been trolling acts. A little habitat was one sex, little habitat for days now, looking for them in all sorts of places that looked much more like me than this ever would. And here we have it. Oh, look, he broke. We brought a goldfish bowl with us. Pop it in there. Oh, my goodness me Finally, we have got at axe a little relief that they're here. The relief from itself that I've actually C one now seen one being pulled out. The water on the relief that there is with this net is a bit of hope. It is a tiny, tiny, tiny little bit of hope, but it is hope nonetheless. And we have to cling to hope for not just the axle little sight but our own. We need the extra little, like the excellent will needs us. 20 years I've been breeding these things every time I look in excellent. I wondered about where it lived in the wild. They live here in the 1968 Olympic rowing course. Vest in that cast, Vicky the best pointing great best accidental information one could have at hand. For two decades. This has been my weird creature, my favorite pet, my ultimate amphibian. And at last I've got my hands on a really wild Mexican axel Akel from Sochi. Milko, the heart of real axe. A little country. But Vicky is about to burst my bubble. She's not convinced that the rowing course counts as a world environment. It all. I tried to search it all over the whole ecosystem. This is not connected to the rest of the ecosystem on. As you point out, there's no agricultural lands here. So for me, it's like, this is not exactly what's going on in the rial thing. In the 180 kilometers an outsider. This is poem that, uh, fish. It was a very a very diplomatic answer. Vicki's point is valid. This isn't a natural wild environment, but the axle bottles don't know that. And they got here under their own steam. Nobody put them here, right? So I mean, they were in the other part of the Sochi Milken. They saw this area and they decided to invade this area. And they have been performing really, really well in general terms. So they are survivors. Basically, they survive in better conditions, and they can survive in this really battle condition, which means it doesn't mean that. Okay, then forget it. And then we can put everything to ravish. No, I mean, we have to take care about him. I can say, even if it is a relic population, that's that's that's colonized here, its own, its own. Under his own steam, it may be the only relic population left. Judging by the figures that you've been getting in your studies of elsewhere in such milk. Oh, so this could be it. This this may not be natural that this could be these two lanes that we can see. However long they are, it could be the future of acts a little. So for me, this is world enough. The fact that we've pulled an adult healthy looking ex a lot out of a rowing course is good enough for me. Whether it's a channel cut 1000 years ago or in 1968 doesn't matter. This is as close as you could get. Toe a wild acts a lot. My baby will go back to the lab to help with Lewis's research before being released Bank where he was caught, data he provides would be vital in understanding how Axel evals fit in to the wider Sochi Milko ecosystem.
