What is the description of a woodlice?

Woodlice, commonly known as pillbugs or sowbugs, are small crustaceans typically found in damp environments. They have a segmented, oval body covered by a hard exoskeleton, which can range in color from gray to brown. Unlike insects, they have seven pairs of legs and are known for their ability to roll into a ball when threatened. Woodlice primarily feed on decaying organic matter, playing an important role in the ecosystem as decomposers.
