Lumps

[markholder42]

Hi all, not sure if this is the right place, I'm not great with tech.
I have a juvenile Mexican red knee, I've had her around a month. I have noticed two small lumps on the underside of her abdomen. They look like nipples but obviously they are not. Does anyone have any idea what they are?

The lumps you have noticed are her book lungs- it's how they breathe so you have no need to worry

They're the Ts book lungs.
Have a look at this http://www.priscillava.com/bbc-journey-inside-a-giant-spider.html. If you scroll down to Respiration it tells you how they work.

Oh no, how silly do I feel now? Been keeping spiders for years and knew about book lungs but never noticed them so pronounced before.
Thankyoy

Don't feel silly.. Always good to ask for help/advice or any questions about anything on here

Your not alone. When I saw my T's book lungs for the first time I was like, what the heck are these flappy thingies?
