Ever since I've been in the hobby, I have always been fascinated by the tarantula foot (hence the username.) Feel free to post pics of you tarantula's tarsus pads! (What an odd thing to say :rofl:)

Cute! I don’t have any pics, but I think their feet are adorable. Like fluffy slippers. Love your pics and the drawing is fab. :D

does anyone know if they have the ability to retract the claws on their feet? Or are the claws fixed in place?

Yes, they can retract their claws, as you can see on my C marshalli in my first post. The feet of the A chalcodes and H gigas have the claws retracted too.

Also noticed that my lp has little spikes on her tarsal claws, anyone know what these are or what purpose they serve?
Biology of Spiders doesn't specify, but since many spiders' tarsal claws are serrated or bristled, I would theorize they help improve grip.

Biology of Spiders said:
Other autapomorphies of the Araneoidea are serrated bristles around the tarsal claws (used for grasping the silk thread; and a typical scaly surface structure of the cuticle.
Biology of Spiders said:
The middle claw is important for web spiders, because they use it to catch hold of the silk threads of their webs; in fact, only the middle hook and not the large main claws grasps the thread. The thread is pushed by the middle claw against serrated bristles situated opposite the claws. There it is held, snagged in the little notches of these bristles. To release the thread, the middle claw is lifted by the musculus levator praetarsi; the inherent elasticity of the thread simply causes it to spring back out of the clasp of the claw.
The ridges on the claws may be a vestigial feature:

Biology of Spiders said:
Two claws must be the derived condition. It is assumed that the third claw (middle claw) was reduced in several spider families during the transition from a life in a web to free hunting.
