Polyzonium germanicum, also known as the Kentish pinhead [1] is a species of millipede within the genus Polyzonium and family Polyzoniidae.
Polyzonium germanicum is a distinctive looking arthropod with a very small triangular shaped head. [1] P. germanicum can range from 5mm to 18mm in length. [1] Unlike most millipedes this species hatches with 4 pairs of legs, as opposed to the usual 3 pairs that most other millipede species hatch with. [2] P. germanicum possesses a brownish orange body. [1] P. germanicum possess ozadenes, however they are not present in the first 5 body segments of the organism. [3] These ozadenes will secrete an irritant monoterpene substance to discourage predators. [3]
Polyzonium germanicum has an extensive range throughout Europe, where it inhabits both Temperate and Mediterranean climates. The species has been recorded within the countries of: Albania, Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Italy, Latvia, Lithuania, Moldova, Montenegro, North Macedonia, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, United Kingdom and Ukraine. [4] [5]
Polyzonium germanicum is a species associated with woodland habitats where it has been recorded to live in mixed deciduous and coniferous woodlands on chalk soils. [1] The species has also been known to live in areas of mature coppices of Castanea sativa and Corylus avellana . [1] Populations are highest in woodland and forest habitats containing coarse woody debris. [6]
In Slovakia P. germanicum has been recorded living in beech forests at 700–1100 meters above sea level. [6]
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of Eumillipes persephone, which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures.
Centipedes are predatory arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful stings, injecting their venom through pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs.
Pauropoda is a class of small, pale, millipede-like arthropods in the subphylum Myriapoda. More than 900 species in twelve families are found worldwide, living in soil and leaf mold. Pauropods look like centipedes or millipedes and may be a sister group of the latter, but a close relationship with Symphyla has also been posited. The name Pauropoda derives from the Greek pauros and pous or podus, because most species in this class have only nine pairs of legs as adults, a smaller number than those found among adults in any other class of myriapods.
Myriapods are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial.
The speckledblack salamander, previously known as just the black salamander, is a species of salamander in the family Plethodontidae. It is endemic to the U.S. state of California. Its natural habitats are temperate forests and temperate grassland. It is threatened by habitat loss.
Polydesmida is the largest order of millipedes, with more than 5,000 species, including all the millipedes reported to produce hydrogen cyanide (HCN). This order is also the most diverse of the millipede orders in terms of morphology. Millipedes in this order are found in all regions of the world other than Antarctica.
Shebenik National Park is a national park in eastern Albania adjacent to the border with North Macedonia. It encompasses 34,507.9 hectares (345.079 km2) and is specifically marked by a mountainous landscape supplied with glacial lakes, valleys, dense coniferous and deciduous forests and alpine meadows and pastures. Elevations in the park vary from 300 metres to over 2,200 metres above the Adriatic at the peak of Shebenik and Jabllanica, hence the name. It dwells a number of endangered species that are fast becoming rare in Southern Europe, including the brown bear, gray wolf and balkan lynx. The abundance in wildlife can in part be explained by the variety of vegetation types and remote location.
Sphaerotheriida is an order of millipedes in the infraclass Pentazonia, sometimes known as giant pill millipedes. They inhabit Southern Africa, Madagascar, South and Southeast Asia, Australia and New Zealand. Like the Northern Hemisphere pill millipedes of the order Glomerida, these millipedes can roll into a ball when disturbed. When they are rolled-up, most sphaerotheriidans reach a maximum size of a cherry or golf ball, but some species from Madagascar can even reach the size of an orange. When rolled-up, predators are unable to unravel giant pill millipedes since the margins of their second and last dorsal plates fit perfectly into one another, creating a sealed ball. A few giant pill millipede species are able to produce sound, the only millipedes known to do this. This order of millipedes is also unique in that some African species are used for medicinal purposes.
Xystodesmidae is a family of millipedes in the suborder Leptodesmidea within the order Polydesmida. The family Xystodesmidae was created by the American biologist Orator F. Cook in 1895 and named after the genus Xystodesmus. This family includes more than 390 known species distributed among 62 genera. Many species, however, remain undescribed: for example, it is estimated that the genus Nannaria contains over 200 species, but only 25 were described as of 2006. By 2022, 78 species in Nannaria have been described.
The greenhouse millipede, also known as the hothouse millipede, short-flange millipede, or garden millipede, is a species of millipede in the family Paradoxosomatidae that has been widely introduced around the world, and is sometimes a pest in greenhouses.
Glomeris connexa is a species of pill millipede within the genus Glomeris and family Glomeridae.
Trachysphaera is a genus of dwarf pill millipedes in the order Glomerida. Just over 30 species are known, making it the third most species-rich genus of Glomerida. Trachysphaera species are patchily distributed throughout Europe and western Asia, extending from Spain to Caucasia. Members of this genus are tiny, with modified appearances resembling that of calcareous stones.
Polyzonium is a genus of millipedes belonging to the family Polyzoniidae and order Polyzoniida.
Geophilus osquidatum is a species of soil centipede in the family Geophilidae found in western Europe, from mainland Spain through western France to Britain and Ireland, though it's also been recorded in Italy, Czech Republic, and Germany. Males of this species have 51 to 57 pairs of legs; females have 53 to 63 leg pairs. This species grows up to 30 millimeters and is bright yellow with a darker reddish head. Because of this, it's often confused with G. flavus and G. gracilis. Its subspecies, G. osquidatum porosum, was found synonymous with G. flavus. In Britain, G. osquidatum is found in a wide range of habitats including woodland, grassland, and coastal shingle as well as gardens and waste ground.
Geophilus richardi is a species of soil centipede in the family Geophilidae. This centipede is found in France and Monaco in the Western Alps and on the Italian mainland, Sicily, Sardinia, and the Ionian Islands. This species is notable as one of only two in the family Geophilidae to include centipedes with as few as 29 leg pairs.
Trachysphaera lobata, also known as the sand pill millipede, is a species of pill millipede within the genus Trachysphaera and family Glomeridae.
Telekia speciosa, also known as the heart-leaved oxeye or yellow oxeye, is a species of flowering plant within the family Asteraceae.
Schendyla is a genus of soil centipedes in the family Schendylidae. These centipedes are found in the west Palearctic region. This genus was described by Danish entomologists Vilhelm Bergsøe and Frederik Vilhelm August Meinert in 1866. This genus now includes more than 20 species.
Petaserpes rosalbus is a species of millipede within the family Polyzoniidae. It is one of six recognised species within the genus Petaserpes. The species is native to North America, where it can be found living within the state of Virginia. P. rosalbus has been recorded to inhabit mountainous habitat at elevations up to 762 meters above sea level.
Devilliea tuberculata is a species of flat-backed millipedes in the family Xystodesmidae. Like other members of the genus Devillea, this species is limited to caves. This millipede has been found in several caves in the Alpes-Maritimes department of France. This species is notable as the first millipede in the order Polydesmida found to feature more than the 20 segments usually found in this order.
