Armadillidium (/ ɑːr m ə d ɪ ˈ l ɪ d i ə m /) is a genus of the small terrestrial crustacean known as the woodlouse. Armadillidium are also commonly known as pill woodlice, leg pebbles, pill bugs, roly-poly, or potato bugs, and are often confused with pill millipedes such as Glomeris marginata.

Armadillidium vulgare, the common pill-bug, potato bug, common pill woodlouse, roly-poly, slater, doodle bug, or carpenter, is a widespread European species of woodlouse. It is the most extensively investigated terrestrial isopod species. [ 2 ]
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda.Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals.
Reinforced thermoplastic pipe (RTP) is a type of pipe reinforced using a high strength synthetic fibre such as glass, aramid or carbon. It was initially developed in the early 1990s by Wavin Repox, Akzo Nobel and by Tubes d'Aquitaine from France, who developed the first pipes reinforced with synthetic fibre to replace medium pressure steel pipes in response to growing demand for non-corrosive ...
Basic body regions of the woodlouse. The woodlouse has a shell-like exoskeleton, which it must progressively shed as it grows. The moult takes place in two stages; [35] the back half is lost first, followed two or three days later by the front. This method of moulting is different from that of most arthropods, which shed their cuticle in a ...
Cubaris murina, commonly known as the little sea isopod or little sea roly poly, is a species of woodlouse in the family Armadillidae. It is found in North America, Africa, South America, Australasia , tropical Asia, and the Pacific Ocean .
Metal bellows are created by rolling annular corrugations into a smooth extruded or welded pipe. In 1946, Dreyer developed a multi-walled joint that was designed to accommodate axial movements as well: the axial expansion joint .
