Question

Quizplus · Accepted Answer

The best choice to avoid being poisoned by noxious gases while inside a ball of dung is by closing the spiracles. Spiracles are the tiny openings on the skin of insects that allow for the exchange of gases (oxygen and carbon dioxide) between the environment and the insect's internal system. By closing these openings, the dung beetle can prevent the entry of harmful gases into its body while laying its eggs in the ball of dung.
