Woodlice
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. This makes them quite unique among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment. Woodlice have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments like those of the genus ''Ligia''. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (:wiktionary:conglobate, conglobate) as a defensive mechanism or to conserve moisture; others have partial rolling ability, but most cannot ...

Hemilepistus Reaumuri
''Hemilepistus reaumuri'' is a species of woodlouse or isopod that lives in and around the deserts of North Africa and the Middle East, "the driest habitat conquered by any species of crustacean, not including insects which are now known to be crustaceans (see pancrustacea)". It reaches a length of and a width of up to , and has seven pairs of legs which hold its body unusually high off the ground. The species was described in the ' after the French Campaign in Egypt and Syria of 1798–1801, but was first formally named by Henri Milne-Edwards in 1840 as ''Porcellio reaumuri''. It reached its current scientific name in 1930 after the former subgenus '' Hemilepistus'' was raised to the rank of genus. ''Hemilepistus reaumuri'' occurs at great population densities and fills an important niche in the desert ecosystem. It feeds on plant leaves, obtains most of its water from moisture in the air and sand, and is in turn an important prey item for the scorpion '' Scorpio maurus''. '' ...

Isopod
Isopoda is an Order (biology), order of crustaceans. Members of this group are called isopods and include both Aquatic animal, aquatic species and Terrestrial animal, terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of Antenna (biology), antennae, seven pairs of jointed limbs on the Thorax#In_arthropods, thorax, and five pairs of branching appendages on the Abdomen#In other animals, abdomen that are used in Respiration (physiology), respiration. Females brood their young in a pouch under their thorax called the Brood pouch (Peracarida), marsupium. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are Grazing (behaviour), grazers or filter feeders, a few are Predation, predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or the bottom of freshwater body of water, bodies of water, but some Taxon, taxa can swim for short distance. Terre ...

Armadillidiidae
Armadillidiidae is a family (biology), family of woodlice, a terrestrial animal, 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. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters, potato bugs, curly bugs, butchy boys, and doodle bugs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, ''Armadillidium vulgare'', was introduced to New England in the early 19th century and has become widespread throughout North America. Common names Ecology and behavior Pill bugs in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as ''Volvation, conglobation''. Conglobation has evolved independently in se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcheta
''Mesoniscus'' is a genus of woodlice, placed in its own family, Mesoniscidae, and section, Microcheta. It contains two species – ''Mesoniscus alpicolus'' and ''Mesoniscus graniger'' – that live in Central and Eastern Europe, mostly in and around caves. Distribution ''Mesoniscus'' is restricted to Central Europe and the Balkan Peninsula; the ranges of its two species do not overlap. ''Mesoniscus alpicolus'' is found in Lombardy and the Northern Calcareous Alps. In Austria, its range extends from the near Innsbruck to the eastern edge of the , although it is also found in isolated pockets of Triassic and Silurian–Devonian limestone in Styria. ''Mesoniscus graniger'' has a wider distribution than its congener; it is found in much of the Carpathians, including the Bihor and Banat mountains, and in the Dinaric Alps and Julian Alps. It is also found in the Caves of Aggtelek Karst in Hungary Hungary is a landlocked country in Central Europe. Spanning much of the Pa ...

Armadillidae
Armadillidae is a family of woodlouse, woodlice (Oniscidea; terrestrial crustaceans), comprising around 80 genera and 700 species. It is the largest family of Oniscidea, and one of the most species-rich families of the entire Isopoda. Most of the armadillidae taxa are not monophyletic. Armadillids generally have a strongly convex body shape, with some rather shallowly convex. Like members of the woodlice family Armadillidiidae, armadillids are capable of enrolling into a sphere (conglobation), and are commonly known as pill bugs. Some species, however, have secondarily lost their conglobation ability. For example, a species exist in which the males lack the inner face of the coxal plates and are therefore unable to conglobate. Armadillids differ from the Armadillidiidae in that the antennae are fully enclosed within the sphere. Species of Armadillidae occur in a variety of habitats including forests, savannas, and arid regions. Armadillids occur natively in the Afrotropics, A ...

Crustacean
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans ( oligostracans and multicrustaceans). The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ligia
''Ligia'' is a genus of isopods, commonly known as rock lice or sea slaters. Most ''Ligia'' species live in tidal zone cliffs and rocky beaches, but there are several fully terrestrial species which occur in high-humidity environments. Ecology Coastal ''Ligia'' species exhibit a mixture of terrestrial and marine characteristics, drying out easily, needing moist air and proximity to water to retain water. While they have gills and can exchange gas under water, they only do so when escaping terrestrial predators or being dislodged by wave action. They do not move swiftly in the water and are open to marine predation. They are well adapted to rocky surfaces and avoid sand, which opens them to terrestrial predation and desiccation. Taxonomy It has been suggested that ''Ligia'' is more closely related to marine isopods than it is to true woodlice Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from lou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizidium Tiberianum
''Schizidium'' is a genus of woodlice, found from Greece to Iran. Description It has a convex body, and is capable of volvation (rolling into a ball) without leaving fissures. It has small eyes with several ocelli. Its telson The telson () is the hindmost division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment (biology), segment of the arthropod body, or an additional division that is not a true segm ... is triangular and its uropods are similar to those of '' Armadillidium''. The first joint of the antenna is remarkably small, being only about half as long as the second. Ecology The species of the genus appear in three varieties: Fully epigeal (land-living) species, mostly moving around at night and hiding under stones during the daytime, these species are fully pigmented; endogeal species, which mostly live interstitially, are generally depigmented with reduced sizes and eyes, and cave-dwelling spe ...
