If you want to get to know them better first, check out their latest KZbin video saving lost frogs in Ecuador: planetwild.com/r/oddanimalspe...
This video discusses the history of frog pregnancy tests and chytrid fungus. Before at-home pregnancy tests existed, people used frogs to determine if they were pregnant. The use of frog pregnancy tests had incredibly terrible consequences for amphibians around the world. When these frogs were eventually released from their labs, they spread a deadly fungus, called "chytrid fungus" or Batrachochytrium dendrobatidis, across every continent. This caused amphibian populations to plummet across the world and many amphibians went extinct entirely. In telling this story, this video answers the following questions:
How were frogs used as pregnancy tests?
Were frogs used as pregnancy tests?
What is chytrid fungus?
How bad is chytrid fungus?
How did chytrid fungus spread?
How does chytrid fungus affect amphibians?

So in other words, the frog extinction wouldn’t happened if us human either 1: import them back to their homeland and release them or 2: Put them down since they’re considered invasive species to the other lands.

[@CormacHolland]

Unfortunately, our understanding of the ecological world was not as advanced as it is today. There are countless examples of introductions (both intentional and unintentional) across the planet having unforeseen impacts on their environment.

Here I am, a herpetologist, screaming “THE CHYTRID FUNGUS” at my screen at 6:16 Can I get my medal now? because I’m in massive college debt and I need something to show for it.

[@hopelessopus660]

So basically, we released frog plague 😢 Another story of humans thinking they know what they are doing and destroying nature and the beautiful variety of animals in it. 😢 In the end, we will end up in a desolate, barren world devoid of any diversity in its flaura and fauna, devoid of everything that once made it beautiful and most importantly devoid of all the qualities that made it livable for us and that will be the price for our hubris. The saddest thing is that we will deserve it too.😢

[@the_newt_nest]

To lull you into a false sense of security. Not only do they have fungus but they're vicious. If you have them in an aquarium, they'll eat all the other animals in the tank.

[@Malboop]

i knew about this for a while. been waiting to see a video like this, you did really well brother!

[@user-pf3cu4lo7u]

I had no idea thats how chytrid originally began spreading... i need to research this more. Insane

[@MermaidMakes]

Isn’t it crazy?! I studied herpetology in college... it really adds an extra heaping layer of misanthropy to your day. The Good news is, there’s some hope. If herpetologists act quickly enough, many amphibians can breed in captivity and eventually be reintroduced, and there are many studies being conducted to help find an ecologically safe solution. Look into the Golden Panamanian Frog, though. I wanted to get a tattoo of one, because to me they represent overcoming adversity, against all odds. When I saw some in an exhibit at the Atlanta zoo, I am not exaggerating when I say that I cried- because it meant that the population that the team collected were successfully breeding.

That was very interesting to listen to, thank you for your work!:D P.S. to be honest I'm really disappointed how many people here being not so polite about the video. Like, it's interesting from the view of science, why you need to comment "whо аsk"? The creator put a lot of effort in his videos to make them interesting but straight to the point at the same time. P.P.S. I may have some mistakes here, sorry for that, English is my third language I started to learn, so I'm not that good in it.
