Our adult tuatara are officially in torpor! Tuatara do not hibernate, they enter a state of torpor, which is a state of inactivity to save energy during times of decreased temperature and food supply. We keep their burrows heated just to keep them from freezing, but they’ve evolved to survive harsh changes in temperature and will only breathe a couple of times in an hour during this state. Did you know you could put a tuatara in the fridge for six months and they would survive? Don’t worry, we wouldn’t put ours in the fridge!
