Anatomy of the Fort Hall Baboon

[Stefan]

Hello there,

I have noticed that on my Fort Hall Baboon (Pterinochilus lugardi) There are two small spikes just below the spinnerets. They are small and seem to have no purpose. Does anyone know what they are?

Kind Regards,

Matthew

Hi,
They're a second pair of spinnerets. All tarantulas have 4 spinnerets: 2 big ones & 2 small ones.

That's a great picture. I have never seen this is any book. Also I have never seen it on my other tarantulas because there all black lol. Thanks for adding the picture.
