My P. murinus hisses like crazy too! It's kinda cute, sometimes I disturb him (lightly blow on him) so I can hear it.

Here's the stridulation of a Ceratogyrus cornuatus as recorded by Tom from bighairyspiders.com.

When are the hissers generally angrier/more scared? When they hiss or when they rear?

 

[Bean]

The C. marshalli I have stridulates when she is in the defense posture.

So stritulating is a little freebe when it poses? So Ts never stitulate without posing?

 

[Fenris]

My P. murinus never stridulates unless in threat posture. You can see his chelicera moving up and down vigorously when he hisses. It's quite the intimidating site.

My 4.5" T. blondi can do it fairly audibly. My crawshai is still very small though.
