Where did rolly pollies come from?

Rolly pollies, also known as pillbugs or armadillidiids, are terrestrial crustaceans that are believed to have evolved from marine ancestors. They are thought to have adapted to life on land around 300 million years ago, during the Carboniferous period. Their ability to roll into a ball as a defense mechanism is a key characteristic that helps them survive in terrestrial environments. Today, they are commonly found in moist habitats worldwide.
