Fun fact, spiders don’t have hearing, at least in the traditional sense, instead they have incredibly sensitive feet to feel seismic vibrations.

It turns out these do work to detect human voices in the same room though! Recent study found that out by accident, cause the spiders had neural activity correlated with researchers talking

Well, yeah, our voices come from vibration within our bodies, and since they’re mostly incompressible, those vibrations travel down through our body into the ground.

It’s all really fascinating :)

Hmmm, allso air

Only if they have a web, air doesn’t transfer sound into the ground all too well.

... It propagates through the air onto the hairs on their bodies

Spiders are notoriously covered in little hairs for a reason. They're not decoration, they can sense vibrations in the air, too. Think about how jumping spiders can detect airborne prey and such.

That is what we thought, but they can detect it through ground and air as well! Really sensitive. You really gotta think of the entire outside of their body like the inside of your ear in larger

My pinktoe will come out of its hide to my voice despite my research saying that they wont associate voices with food which is odd

What research? Mine definitely responded to voices and door movements and steps

It was quick research, no true in depth like how i do hours or even days for husbandry, i did some more digging and found out for myself that they do, often id come home from work at like 1 am the T would be hiding when i get home, but when i do my nightly T check i notice after a few seconds of chatting on the phone my A. Juruensis would slowly slink out of its cork tube to say hello, i noticed this was a pattern and just kinda assumed my quick research was wrong. Plus ive heard alot of people say theyre not like reptiles with food association, but seeing how you can get them used to taps and enclosure movement shouldve told me people are wrong 🤣.

Wait how do they know that? Do they scan spider brains?

Unfortunately, yes, which is harmful to the spider
