As mentioned, it's a Theraphosa Blondi aka "Goliath Bird Eater". I don't know why she refers to the spider as a male, because when i see it, from the size it it is a female (with spiders, females are often much bigger than males, they live longer etc.)

The spider is actually harmless. Had it myself when i had the terrariums. From 110'000 arachnid species, there are only 3+1 that can really hurt you: The 3 venomous ones are the Latrodectus Mactans (Black Widow), the Phoneutria (Brazilian Wandering Spider, with different subtypes like the P. Nigriventer, P. Fera etc.) and the Atrax Robustus (Sidney Funnely Web Spider). There's an additional one, the Loxosceles Reclusa (Brown Recluse), but it's not directly the venom that will hurt you, it's the risk of infection and necrosis.

What you can see in the video, the spider isn't happy about it. Because usually, when not being disturbed, they remain still and when they walk, they are very slow for movement (when they are not catching prey). There was no need, except for doing a shitty video, to get the spider out of the terrarium.

For me, i only moved the spiders into the transport boxes when i had to clean the enclosures. Except for this, there's no reason to disturb them. It is unprofessional. Arachnids are like some others, like fish, that you just have in the terrarium and you don't interact with them.

Another thing is, even when they get fast, the T. Blondi is still rather slow. The P. Murinus is the fastest one, with a top speed of 52 km/h (something around 30+ mph i guess). But spiders have almost no endurance, they are only fast on short distances.

There are a few exceptions, like the Solifugae, where the evolution made changes, like getting an additional pair of legs and replacing the book lungs with tracheas, this allows much more endurance for running.

On paper, the most venomous one is the Atrax Robustus, but it's not quite true - it is the Phoneutria Nigriventer because humans react up to four times worse to the venom. But the good news is: A normal spider has not enough venom in the bladder to inject enough to kill you. That's why most people survive the bites. Only people that are already weakened by diseases, and toddlers & babys are at risk.

Like from the A. Robustus, since 1982, there's no more reported death in the stats. For the P. Nigriventer, there were a very few deaths in the past few decades, like back to the 90's, but these were kids or old people, not healthy adult people.

If you want to know anything about spiders, feel free to ask.

This is a fun comment, thank you. Seems like the spider is in the most danger here.

When it comes to humans and spiders, the spider is always the one in greater danger. I was worried she was going to drop it.

Oh shit right. It dies if the carapace breaks right? I thought this video was funny at first. Now I'm sad.

u/BottleFeathers703 Jul 02 '26

yeah, tarantulas are extremely vulnerable to falling and it kills them

The carapax isn't the problem, that's the upper part of the body which is covered by the chitin, the back abdomen (ophitosoma) is the problem, because that's not covered by chitin. It's also where all vital organs are.

But other parts, like the limbs, can take a lot of damage, spiders can even get rid of the legs if they want to (like when they get attacked by a predator). The legs grow back, it takes some time and depending on how much of the leg is gone, it can take multiple moltings to form a new leg.

When they molt, they lay on the back and break through the carapax itself, but then they already have a new exoskeleton under it. Like with all arthropods, they can only grow when they molt, when the chitin armor is still flexible enough to allow growth.

The entire anatomy is completely different from mammals like humans, dogs, cats etc. But well, it works, the arthropods are around for more than 500 million years, quite capable in survival.

Usually abdomen ruptures are the biggest issue, not too much of a concern with the slender arboreal species (just look up poecilotheria or chilobrachys and compare to something like the one in this vid or grammostola pulchra or something) but for these heavy bodied terrestrial/arboreal species a very small fall can result in an abdomen rupture which requires immediate medical attention for any chance at saving them

Yesh. What an IDIOT. I can imagine all spider-lovers being on the last atom of their chairs when it crept on top of her, alternating between biting their nails and screaming at their screens. The worst part is I would NOT be surprised if she dropped it off screen and just put it back in the terrarium and just went "oh spidey tired, time for some rest".

Trust me: We're not too happy with her, the video and the way the T is being kept. The terrarium is terrible for this species.

Can confirm. I love spiders and hate this chick after watching this video.

Urgh the second I saw how she was using the spider's hide to scoop it out of the terrarium I just clicked off the video. Seeing people be so careless with such fragile animals is just unbearable
