Underneath moist logs and decaying leaves live a multitude of creatures, several of which may be terrestrial isopods, commonly known as sowbugs, woodlice, pillbugs, and slaters.
Some species are able to roll themselves into a ball to conserve moisture or as a defence mechanism. There are over 10,000 species of isopod worldwide with around 4,500 species found in marine environments, mostly on the seabed, 500 species in fresh water and another 5,000 species on land.The order is divided into eleven suborders.he majority of crustaceans are aquatic and the isopods are one of the few groups of which some members now live on land. The only other crustaceans which include a small number of terrestrial species are amphipods (like sandhoppers) and decapods (crabs, shrimp, etc.).
