Crayfish have gills for breathing underwater, but can also breathe air.

Are crayfish lungs or gills?

Mandira P. Crayfish is a member of aquatic arthropod class Crustacea and they possess gills for respiration.

How do crayfish breathe out of water?

Crayfish use gills for breathing, but can survive out of water for several hours. Crayfish are attractive, beautiful freshwater lobster-like creatures.

Note: To be precise, the gills are located on the outside of the body cavity in a space between the body wall and the carapace. The carapace does not fit tightly against the body of the crayfish, there is a space between the body and the carapace so water can circulate through the gills.
