There are just way too many burrowing tarantulas to answer this question. Assuming you are interested in the tarantulas you mentioned we can help you there.. but otherwise, you need to be more specific on the tarantula you are interested in. We could be here all day compliling a list of burrowers.What species should be considered terrestrial or burrowing? Pt murinus and C. fimbriatus for example, should be considered burrowing? What about T. blondi?
As long as most T's would use a retreat, what shlud them be considered?
