I was wondering what they did about the thoracic spiracles. It appears they insert auxiliary O₂ tubes directly into the spiracles. I wonder whether they tried closing them off entirely? Since the whole tracheal system is internally contiguous, I think it would be simpler to just seal the thoracic spiracles and rely on the abdominal ones.
