      @Zeev tastefully used “bad” language is patently hilarious by every normalized standard of comedy. It’s an aspect of culture and can be a tool used to great effect. If you don’t like it, it’s your issue to grapple with not the artist’s.

      @Philip Spencer Fauci was not doing science he was doing “informed policy”. Science is what he did in his career before being appointed. He tried to be informed as best he could and tended to do the safe thing rather than the bold thing [in his estimation].

    I got a tarantula as a teenager without knowing anything about tarantulas and the first time it molted I honestly thought it died. It was late so I figured I’d deal with cleanup the next day. When I got home from school I picked up the molt and was like, that ain’t right, and the tarantula crawled out from under its log and was like Yo, whattup? Had dozens of pets of dozens of varieties and none were as gentle as that tarantula (Chilean Rose)

    • Panda Funkey says:

      that is so wholesome and cute x3

    • Adek says:

      When I got my first tarantula as a 12 yo (a B. smithi) I knew that they molt, how it looks like and how to notice an upcoming molt. But still when she had her first molt at my home it was at night while I was sleeping. Next day I look into the enclosure and see more legs than usual, so I was like ”wtf how are there two spiders all of a sudden?!”.

    • Scriblyn says:

      Omgg how does it feel to live my dream. Tarantulas are so beautiful

    • Nicolas Ruesch says:

      Same! I had a mexican painted tarantula when I was 15 yo. I was so sad when that happened. I thought it was my fault because I hadn’t taken good care of her.

    • _God _ says:

      I got a rose hair as my first tarantula too and after about 8 or 9 years of having her I got 3 more, a togo starburst baboon, green bottle blue, and a metallic pink toe

  4. A Laughing Wolf says:

    No matter how Zefrank’s narrator describes things, it always manages to be funny yet still informative at the same time, truly a one of a kind

  5. Alexis Condit says:

    I have a tarantula as a pet, they really are cute, and really beautiful. I used to be scared of spiders, but the more you learn about them, the more you appreciate how amazing they are.

    • celestialraevyn says:

      @Penny Trui I’m glad you’re trying your best not to kill them 🙂 you should watch videos of jumping spiders. It may sound scary to an arachnophobe but they’re actually adorable and extremely intelligent and lots of people have said that they’ve cured their arachnophobia from watching videos of them.

    • Penny Trui says:

      Cute???? My scary ass is like sorry nope I’m so terrified watching this 😳. Honestly, I’m trying to get rid of my fear of spiders but it’s so freaking hard that my hair immediately stands up when I see one. Right now I’m just working on not killing cellar spiders since they kill other spiders. I rather have tiny cellar spiders than big house spiders

    • sasparilla says:

      Regularly seeing and observing my friend’s tarantulas was supposed to alleviate my strong irrational arachnophobia but all that happened was my brain went “tarantula in a glass box? You’ve become unafraid of it, so it must not a spider. Cellar spider in the corner above the light? Fuckin PANIC”

    • Regunes says:

      kind of a shame they’re not developped enough to be real pet. Then again squids can go depression mod if you don’t stimulate them.

    • Some guy says:

      Yes, I’m so glad I get to see how derpy and majestic they are now that I’ve worked on my fear

  6. Michael Nash says:

    I am a veterinarian. One day I had a potential client call on the phone with quite a conundrum. He had a tarantula and he was, by his own admission, afraid of it. This guy wanted me to do an operation on his tarantula and remove its fangs because, as I mentioned earlier, he was scared of being bitten. I had to explain to him the several things wrong with that idea: 1) If this were to be done I don’t know how i would anesthetize the spider since they don’t have lungs for inhalant anesthesia and I certainly couldn’t inject the spider with valium. I don’t even know if valium will WORK on a spider but I know it would leave a very big leaky needle hole, plus I’d have to get the spider to hold still for it and, well, that wasn’t going to happen. I could have placed the spider in a tank of anesthetic gas but how to monitor it escaped me, as it doesn’t have the usual pulse and respiration, nor could I use a pulse oximeter on it. Even if it would work (which it wouldn’t) I didn’t have one small enough. There would be a very fine line between asleep spider and dead spider and one could become the other quite rapidly.

    2) In veterinary school we are, quite frankly, taught how to KILL arachnids and insects (ticks and fleas, respectively) rather than operate on them. I suppose I could have opened up a whole new category of service for people with pet arachnids, but I’m sure I’d soon get someone wanting me to de-venom sac their Deathstalker Scorpion and I’m not going there.

    Finally, the 3rd problem with the idea is that if I ‘defanged’ his spider it would very quickly starve to death because it couldn’t inject any venom in its prey. The guy sat quiet for a minute and then said, “I guess a tarantula won’t make a good pet for me if I’m afraid of it.” I agreed. He thanked me and hung up. That still ranks as one of the oddest telephone conferences I’ve ever had.

    • Sci Fi Secrets says:

      @Viktor Jönsson declawing cats…

    • Madeline Gott says:

      Defanging happens on accident occasionally, but the fact is even if you managed to defang his spider and he managed to help it eat (a very hands on process) by making a cricket soup for it to suck up, if it survived long enough to molt (aka grow) it would grow its fangs back!!

    • Femaiden says:

      i inherited a cat that had been declawed (i am not the one who declawed it) and i’m not arguing that declawing the cats is good. i’m just gonna say that my cat didn’t really seem to be in any pain at all? she went about and acted like a normal cat and often would go to the scratching post. .or more often go to the side of my couch and make the clawing motions like she was trying to scratch it up and her paws would just slide across it because she had no claws. . .it was as if she didn’t even know the claws were missing
      again, i would never do this on purpose to a cat, (edit : i was misinformed about what the actual procedure was). i googled it and yeah it does seem like they cut the first segment of bone phalanges off of each “finger” the cat has, because there are claw cells embedded in the bone, so they have to remove the entire bone to keep the claws from growing back and if they do it wrong then the claws grow back crooked and cause problems, but if they do it right, it’s a clean cut that heals. i dunno. i observed my cat and she never showed any signs of being in pain. she lived for 15 years.
      in the end, i agree trying to defang a spider is a bad idea, because how woild you even do that? may as well not even own a spider then.
      although i had often wondered what if someone had a pet cobra snake and defanged it?
      i do know that i read if you remove a scorpion’s stinger, then the scorpion can’t poop anymore amd it will die from constipation. . (i am pretty sure they don’t poop out their stinger?)
      dunno why people want deadly creatures as pets and then want to remove the parts that make them deadly. just get a harmless animal for a pet that has been bred to be harmless and docile towards humans then.
      but then again, maybe those type of people shouldn’t own a pet. there are a lot of people that have pets and aren’t responsible enough that they don’t even know how to care for them and shouldn’t have them

    • Metal Mama Sue says:

      @cam Exactly right. I’ve ALWAYS loved nature’s underdogs like snakes & reptiles. You would be astounded at how many people buy them without knowing sweet f*ck all about them.
      We’ve rescued turtles in tanks that were WAY too small and the owner didn’t know WHY the turtle kept banging against the sides of the tank, 🤦‍♀️ an Iguana that ‘wouldn’t eat’ because the owner thought cold blooded meant they LIKED the cold, instead of tropical warmth and humidity, I could go on & on.
      Perhaps what’s worse is the pet stores that sell them to people who have no clue, and don’t take time to educate & tell them what all they NEED to keep them happy and thriving.
      It’s honestly so wrong, pets of ANY kind are NOT disposable and it’s OUR responsibility to learn how to care for them properly so they live a long happy life.
      If you’re NOT willing to do that, you have NO business owning them.

    • Viktor Jönsson says:

      @The1nvisibleJeevas yeah, i believe so too, but people do in many cases mutilate their pets/livestock to make them more manageable

  7. Tarantula Collective says:

    Wow! You nailed this Episode. Hillarious and extremely informative. Amazing job! Thanks for letting me contribute footage and be a small part of this. 🖖💚🕷

  8. CalderaMan says:

    As someone who appreciates spiders, especially tarantulas, I love this. I also love that first Koalas didn’t give a f***, now crickets. What’s next?

  9. Arthur Taylor says:

    I’m arachnaphobic but this was still really interesting. I love these True Facts videos. Educational and entertaining! And the cricket song was just epic!!

  10. Justin D says:

    Let me tell you something. I am extremely terrified of spiders and bugs. Like seriously scared. However when I watch your videos about bugs and spiders, my fear goes away because you make things interesting and funny. I wish you were my teacher when I was in elementary school.
