What Animal Will Survive When Everyone Dies?

What Animal Will Survive When Everyone Dies?

Hey there and welcome to Life Noggin. Wouldn’t it be cool if there was something
that could survive space without a special suit? Well it turns out there is something that
awesome, and it’s called a tardigrade! They may sound like something you get when
you’re late for school, but these little guys are basically superheroes! Let’s find out why. Tardigrades, or more adorably known as water
bears and moss piglets, are a phylum of small invertebrates that are bilaterally symmetrical
and have four pairs of legs. They like to munch on things like plant cell
fluid and bacteria and try their best to avoid their predators, which can include other tardigrades! That’s right, some tardigrades are cannibals! Talk about trust issues. But just why are these little guys so scientifically
awesome? Well, it turns out that our moss piglet friends
are super resilient and can survive some pretty extreme conditions. They can handle super cold environments, like
ones colder than – 200 Celsius, and also ones as hot as around 150 Celsius! They can also survive extreme radiation, oxygen
depletion, and also severe pressures. Some scientists even think they will outlive
humanity! Tardigrades are also thought of as one of
the few lifeforms that can survive the harsh conditions of space since they have lived
at Low Earth Orbit. In 2007, samples of tardigrades were exposed
to a space vacuum and two different ultraviolet radiation spectral ranges. All of the tardigrade samples were exposed
to both ionizing solar and galactic cosmic radiation. The solar radiation negatively affected their
chance of survival, but amazingly, some of these little fellas were still able to survive! So how do they do it? It’s all thanks to a process called cryptobiosis. Through this, tardigrades practically stop
all metabolic processes and can survive for years in this state. They can dry up into a lifeless ball in what
scientists call a “tun”. They stay in this state until they come into
contact with water again. It’s basically the extreme version of playing
possum. I don’t know about you, but I’d love to
meet one of these superheroes. Oh… well that was easy. But I’d love for my human friends in the
real world to meet one too! Turns out you might be able to if you have
a good microscope. According to some sources, including the awesomely
named International Society of Tardigrade Hunters, if you want to see a tardigrade for
yourself, go out and find some lichen or moss and place it in a shallow dish. Let it soak in distilled water overnight and
in the morning, squeeze the moss over a transparent dish, like a Petri dish, to collect the water. With any luck, you might be able to examine
the water under a microscope and get to meet one of these awesome water bears! I’m going to name mine Heimlich. So what do you think about these little guys? Let me know your favorite fact about tardigrades
in the comments below and let me know of any other amazing animals you’d like to learn
more about! Make sure you come back every Monday for a
brand new video. As always, I’m Blocko and this has been
Life Noggin. Don’t forget to keep on thinking!

  1. Pretty much nothing can hurt the Tardigrade. They don't even have middle school bullies! What would you name your Tardigrade? Let me know down below. Thank you so much for watching! 💙 Loved this episode? You should probably check this one out:

  2. When earth ends: O.o
    People left on earth:

    Water bears left on earth 90000000000000000000000000000000000000*
    water bears:900000000000000000000000 of them*HI!

  3. If we want to live as flawless as this creature we will need to fuse to get ourself 95% human and 5% tardigrades

  4. At school, we looked at pond water under a microscope. We found the tiny bugs and plants, and even a group claimed to see a tardigrade.

  5. My science class went to go get water from a lake and found so many freaking water bears

  6. Consciousness is a fractal (independent of scale). There are many layers to consciousness, in many different forms. We are giants made out of trillions of conscious cells, yet part of One Ocean of Consciousness.
