Pleopodal lungs are an anatomical feature of terrestrial isopods and a component of their respiratory system. They are ancestrally derived from pleopodal gills, and they facilitate gas exchange on land. They perform a function similar to spiracles in insects.[1][2]
Pleopodal lungs are identifiable on woodlice as white patches on the lower five segments (the pleon) on the ventral side (underside). The number of pleopodal lungs varies by species: they may have up to five pairs, or only two pairs as in Porcellio laevis; a minority of species lack pleopodal lungs entirely.[1]
