Parasites?

[schnu]

So I recently bought wood. After working with it I noticed some small "canyons" (not sure how its called), anyway I was wondering if it may be some parasite that damaged the wood. Only one sort of wood (padauk) is affected by these "canyons". I would appreciate if someone could tell me if those are caused by some animals or what could be the cause?

Schnu,

 

It could just be the way the wood was milled.  I found the below doing a quick Google search for the species:

 

Has excellent decay resistance, and is rated as durable to very durable. Padauk is also reported to be resistant to termites and other insects.

I have turned several pens and cigar holders with padauk. To me, that's just how the wood is.

Thank you for the quick answers, the website is very interesting, I didn`t know about it. I was already worried that my little wood stock got insects in it. I guess I can go back to work then. It really is an interesting texture.
