You'd think that there are some features that, once an animal group evolved to have them, could never really go away, right? Well, Stefan is joined today by hosts from PBS Eons, Journey To The Microcosmos, and Bizarre Beasts to break down just how wrong that is! And yes, we will be talking about tardigrades.

    As a geology student, putting the line of symmetry down the middle of the bivalve instead of inbetween the shells hurts me a little bit, because its the main way we distinguish between bivalves and brachiopods
  • @adamphilip1623
    I gotta say I'm absolutely loving the refreshed style on scishow, it's great and the slightly longer videos and new hosts are great too!
  • @falcoskywolf
    What a fun crossover! Seems like Complexly is digging into more complexity with production!
  • Im liking the new style guys. The small mix of comedy into the knowledge is not only refreshing, as a science nerd I feel like it helps people who are here learning for the first time feel more comfortable and open to learning. So keep it up guys! Y'all are a great channel.

    A lot of people I’ve encountered never really progressed past the early stages of being a deuterostome.
  • @DarwinsTable
    Dude, that starfish thumbnail was already great. This headless rhino is just macabre.
  • "Multi-armed head" brought back memories of John Carpenter's The Thing. Evolution was a bit faster in this case though.
  • @halloweendad
    I remember hearing or reading about certain tube worms that have no digestive system. Not even a mouth or anus. They live near volcanic thermal vents and absorb nutrients straight through their skin.
  • The new format is wayyy more entertaining, may the algorithm gods bless Scishow!
  • @JenivieveSteve
    Loving the recent crossovers on the SciShow main channel. I was unaware there were more than just the SciShow spinoffs under the same company and am glad to know more now :)
  • @teresaellis7062
    The wandering head idea reminds me of the one type of vampire which looks human by day, but by night its ears turn into wings and the head flies around looking for a meal.
  • Stefan's acting in this was great. The personality in the script is also really good and refreshing.
  • @peterdore2572
    Im glad Scishow can still conjure up Great and Original Videos after so many years! I love to see the hosts interact like that. Very funny 😊
  • @TJtheBee
    I think the number one thing I’ve learned from this episode is that I never want to step into the ocean ever again.
  • @phionella7
    Im really enjoying the laid-back atmosphere at scishow and todays episode was an awesome collab of 4 of the best channels. ❤
  • @Nee96Nee
    It is so sad that this is the last year of Journy to the Microcosmos.
  • I was expecting to see tunicates on the list. They are some of the first chordates diverge from the rest of us. Their larval form is basically a free swimming fish, but when they mature they metamorphosize into basically a sea sponge and lose the ability to move, their heads and limbs, and most of their nervous system.
  • @KY_CPA
    I love this collaboration so much ❣️ We definitely need more mashups between the completely channels!
