Hello arachnid lovers and I apologize if I’m using the sub incorrectly, but I’m trying to think of a name for groups of spiders (specifically tarantulas and things of that nature) that don’t necessarily use venom to kill. I remember from science class in like middle school our teacher referring to tarantulas as something like old world/barbaric/ancient arachnids. Does this ring any bells? Am I totally off base? Any help would be much appreciated.

The size shrinked was about 1cm, is it dangerous for a pet or a person? Thanks in advance!

Calling any and all spider anatomy experts! I’m currently creating a universe with some spider-human creatures, aiming for maximum accuracy, and Google doesn’t seem to have the answers I’m looking for. Does anyone have a list of organs that humans have that spiders do not? Or vice-versa? Any other cool spider facts/abilities you think should be included in these characters (keeping in mind this is a horror/scifi)?

Thank you for your help!!

Genuine question, I know close to nothing about arachnid behaviour.

We recently visited a "arachnid and insect" travelling zoo. Part of it was that a guy was showing off various arachnids, insects and the odd snake. And he also let people hold them (in their open hands, without moving), often 30-40 people, including children as young as 3, in a row before switching out the animal.

Now, I know enough about the snakes to judge whether they are stressed or unfazed, and those were unfazed. But I can't really judge arachnid behaviour besides when they are threatening because they feel threatened.

He showed off at least 2 brachybalma smithi, a lasiodora parahybana and an emperor scorpion. The presenter at one point said about a smithi that he was doing shows with her for 7 years now.

The spiders were moving slowly, if at all. when not pushing them with his hand sideways, he grabbed them seemingly between their forward body and their abdomen. It was bright, which I think is a contributor because they are nocturnal? Either way they either didn't move or moved slowly. They didn't curl up or threatened. For the scorpion all I know is that his tail was rather raised and he moved a bit quicker, but was easily ushered sideways.

There were no incidents, and for my 6yo daughter it was an amazing experience, because she likes all animals. She was almost soothed by the spiders. But in retrospect, I am not sure how bad it it is for the animals.
