What are spriracles?

Answer 1

Spiracles are small openings found in the exoskeletons of certain arthropods and in the respiratory systems of some other organisms, such as fish and amphibians. In insects, spiracles serve as the entry points for air into the tracheal system, facilitating gas exchange. In fish, spiracles can assist with water intake, especially in species that rely on gills for respiration. Overall, spiracles play a crucial role in respiration and maintaining the organism's respiratory efficiency.
