No, not all. Remember some arthropods are aquatic; the spiracle/trachea/tracheole system utilized by terrestrial insects is largely replaced by gills in marine arthropods.
Spiracles are the means by which insects breathe. They are openings in each side of the thorax and abdomen in most insects. They open into tubes called tracheae which carry oxygen to the tissues in the insect's body.
A spiracle on a stingray is used for breathing. It allows the stingray to draw in water and oxygen while buried in sand or sediment, providing a continuous supply of fresh water to the gills even when the stingray is partially buried.
Insects breathe via holes in their exoskeleton called spiracles. These are normally arranged in pairs, with one spiracle either side of the thorax, or each segment of their bodies. They do not have nostrils like we do.
