I would not say that. Take my Aphonopelma chalcodes for example. Burry has taken to digging a super deep burrow, and has sealed himself (unsexed) in the bottom of his encloser. He has made this large dome under the substrate, and I fine this amazing. This has been going on for about a week, and I am amused that Burry feels relaxed enough to do what he would in the wild.
