Daddy Longlegs Risk Life … and Especially Limb … to Survive | Deep Look


The forest floor is a rough-and-tumble kind
of place. It’s best to stay above it all. This daddy longlegs does just that…on eight
flexible stilts. The end of each leg is multi-jointed. It works like a rope. And see the tip?…There’s a hook there. With every step, he’s grappling his way
over the obstacles in his path. Perfect for off-roading. Even better for climbing. This guy can handle just about anything you throw at him. Those front two legs are also used as feelers… For what’s around the next corner. So really, they only walk on six of their
legs, unlike spider, which daddy longlegs are NOT, by the way. Their closest cousins
are scorpions. Such precious tools require regular care and
grooming. But there’s a downside to having these long limbs. They’re easy for enemies to grab onto. And for that, this daddy longlegs has another
solution. He simply cuts his losses and walks away. We did not not pull that leg! Just the slightest grip, and he’ll drop it. He has a built-in mechanism to pinch it off
cleanly, losing only a drop of hemolymph. It’s called autotomy, the voluntary release
of a body part. That loose limb can create a life-saving distraction… But at a cost. Life without a leg is no cakewalk. Since the limb’s not coming back, the daddy
longlegs has to learn a new way to walk. Ignacio Escalante at UC Berkeley studies how
daddy longlegs do this. Here’s one that still has all eight legs. If it drops one of them… No problem. Escalante calls this movement “stotting.” If it drops a second leg, the daddy longlegs
starts “bobbing” to get around. Lose a third… and he still makes it happen. Don’t feel too bad for him. Even down to five legs, a daddy longlegs can
get back to its original speed in less than a day. In fact, most daddy longlegs deliberately
drop a couple legs in their lifetimes to escape certain death. No big deal — they just let it go. So really, there are second chances in life. And sometimes, a third and a fourth. Hey there, it’s Lauren. You know who’s afraid of creepy-crawly things

  1. I like to imagine all spiders as gentlemen…
    Human: Ah!! A spider!!
    Spider: oh, I am sorry my dear friend! I'll be on my way.
    Human: kill it! Kill it!!
    Spider: oh please don't, I just want..(squish.)

    🙁

  2. Let it Gooooooooo Let it gooooooooooo! That perfect leg is gonnnnnnnnnne! Here I staaaaaan…..((((((thud))))))))

  3. Scientist 1: Okay so today we're going to see how well a Daddy Longlegs walks when it loses a leg
    Scientist 2: Okay, so should I prepare any equipment?
    Scientist 1: No need. I brought my son. He rips bugs legs off better than any machine and it'll give him something to do.

  4. idk why, but the fake slimy, skittery ASMR sounds they always give these videos are annoying. I dont think spiders and bugs are constantly chattering their teeth and making slippery sounds while walking around. makes the vids seem childish

  5. I have these orange ones that run around outside my house, and they don't drop their legs no matter what. I tried to hold one of their legs and it never came off even when I pulled.

  6. Did u guys know that daddy long legs actually have the most poisonous venom in the world. But don’t worry, they can’t get through human skin, they use it to kill mosquitoes instantly

  7. Before when I was younger, I wasn’t able to comment. I asked my dad for permission. He said only for appropriate things, though. I would watch a lot of cartoons. I saw no comments, it was a little glitch. I commented saying something about having no comments and feeling bad. I also added I love unicorns to it. I now contemplate my little kid actions.

  8. You didn’t cover whether they have venom. I’ve heard time and time again that these critters have the strongest venom, but just don’t have a lot, neither the teeth to inject it. Is this true??

  10. I had this guy in our 1st Grade classroom who would capture spiders and make them fight to the death and the Daddy Long Legs was one of them, I think another one was named The Jumpy Spder kinda like Pokemon.

  11. Who else cracked up when that first one started stumbling after losing a limb?
    Ah…. I'm bad. I feel like I've just made fun of the disabled.

  12. Cellar spiders are often called daddy long legs. Opiliones/Harvest men are called daddy long legs. Crane flies are called daddy long legs. This video is showing Harvestmen, which are insects.

  13. I just wanted to say that a daddy long leg is basically a little dot with 8 pieces of black hair. Super cute and coolu could just grab it by their body ( if its not too small for you ) and scare people with it. >;3

  14. So what you're telling me is that there is a researcher out there deliberately pulling the legs of spiders. Which is a sign of sociopath…
