    “Science is sort of a long, passive-aggressive argument about everything” is now my new favorite definition of science.
  • Chris Mayer
    I’m terrified of spiders, yet this webcast about Tarantulas is weirdly fascinating… how very odd 🕸️
  • "And of course the science hippies can't leave that alone" is such a quote for the ages.
  • tpg
    Even as someone who has owned multiple spiders and feels like i know just about everything necessary about them, this was a very entertaining and informative video, and I am always so happy to see good press about spiders of any kind. They're really some of my favorite animals and I wish more people would give them a chance

    I'm such an arachnophobe that I was once "trapped" in the bathroom for almost an hour until my husband came home to remove the spider that was perched on the door frame. And yet, Ze posts a spider video and I watch it, even while eating supper. Only ZeFrank could do that. Thrilled you've got sponsorship for your videos now!
  • I’m in a Box
    Gosh, I love these guys. I find them cute, I gave mine all cute names, Dido, Jumpy, Heisenberg, Icarus and Daedalus. Usually when people call them gross, I point them towards the GBB or the Caribena Versicolour. Or jumping spiders, they’re adorable!
  • I had a tarantula throw it’s hairs into my eyeball once, during a holiday weekend. Worst 3 days of my life. I started panicking about what to do but all I found was a news article and a medical journal entry 🫠

    The entire ophthalmologist office would not shut up about my case, a lot of them had no idea that could even happen to you. I ended up having 7 hairs removed from my eyeball itself and 8 from the surrounding area.

    Upsides? I’m no longer scared of getting lasik, and I ended up being a students thesis and teaching moment about why you never look inside a box with an angry tarantula in it. Ever.

    I had a Chilean Tarantula for 17 years. She was one of the kindest and easiest pets to ever take care of, even easier than owning a plant. RIP Rosy, may you eat your fill of crickets and worms in your heavenly hole.
  • GreenSun
    That tiny frog shown at the end lives in a interesting symbiotic relationship with tarantulas. The frog keep the burrow free from ants and parasites, and the tarantula provides shelter and protection for the little frog, so it's a win/ win situaton for both animals!
  • Randhal Rosie
    Zefrank! Your videos continue to bring me Joy and Knowledge!
  • StillMe
    Love your work. But how's Teddy doing? After your surgery I hope he's OK. Please let us know. Be well.
  • Remember when Zefrank was gone for a few years without any word?
    I'm so happy he came back, love these videos to death.
  • I'm always curious, especially when it comes to spiders and tarantulas and stuff: what is the evolutionary advantage to making reproduction so difficult?
  • I have arachnophobia. Five years ago, after I learned what manifested my fear of spiders, I felt that by 'flooding' my senses with images of spiders would help me tolerate and not freak out when I see these eight legged freaks, especially tarantulas. It took me a few days to work up the courage to view this video and honestly I found it comically informative entertainment. Not once did I creep out or flinched, but laughed. Thank you, Zefrank ❤🕷😊

    I've held plenty a tarantula, but never a Rose-Haired(something Rose, I believe it's Rose-Haired). They are the only tarantulas that make webs and they are the most aggressive. The other breeds are docile, like a curious little puppy. :D

    “Sort of like an upside-down version of the balcony scene from Romeo and Juliet, except they both have bongos and Juliet is potentially a pissed off cannibal” is the best analogy for tarantula courtship I’ve ever heard.

    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.
