Slaters Pillbugs and Woodlice: Isopoda

Terrestrial isopods called pillbugs and woodlice are found in moist situations in a variety of habitats, including deserts. A few blind species live in ant nests. They are usually found under rocks, logs, tree barks, or other objects. Slaters are found along rocky seashores splashed by ocean waves. They also spend time in the water. Others prefer shallow waters associated with oceans, such as bays and estuaries (EHS-chew-AIR-eez). However, most species live in the ocean. There, parasitic species feed on the blood of fish and other crustaceans, such as barnacles, crabs, and shrimps.
