Limacomorpha
Glomeridesmida is an order of millipedes in the infraclass Pentazonia containing 2 families and at least 31 species. Glomeridesmida is the only living order of the superorder Limacomorpha. Glomeridesmidans are small (less than ) and somewhat flattened, and unlike other orders of Pentazonia, are unable to roll into a ball. Ocelli (eyes) are absent. Adult females in this order have 36 pairs of legs and 21 segments, counting 20 tergites plus the anal shield. Male specimens in this order are rare, unknown for all species in the family Termitodesmidae, and known for only a small number of species in the family Glomeridesmidae. Descriptions of mature males in at least three species (''Glomeridesmus spelaeus'', ''G. siamensis'', and ''G. marmoreus'') report 35 pairs of legs, including a pair of telopods, and 20 segments, one fewer than the 21 segments found in adult females. The description of an adult male of another species (''G. indus''), however, reports 37 pairs of legs, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Millipedes
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 the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery 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. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentazonia
Pentazonia is a taxonomic infraclass of millipedes containing the pill-millipedes (Oniscomorpha) which can roll into a ball and the order Glomeridesmida which cannot. Defining traits (apomorphies) include divided sternites, a labrum with single median tooth, and an enlarged pygidium on the hind-most body segment. Pentazonia is in the dominant millipede subclass Chilognatha which have a calcified exoskeleton and modified sperm-transferring legs in males. In contrast to the Helminthomorpha – the other Chilognathan infraclass, the sperm-transferring legs are located on posterior body segments and known as ''telopods''. Pentazonians are relatively short-bodied, with between 13 and 21 body segments. The Pentazonia contains one extinct order, Amynilyspedida Pill millipedes are any members of two living (and one extinct) Order (biology), orders of millipedes, often grouped together into a single superorder, Oniscomorpha. The name Oniscomorpha refers to the millipedes' resemblance t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troglomorphic
Troglomorphism is the morphological adaptation of an animal to living in the constant darkness of caves, characterised by features such as loss of pigment, reduced eyesight or blindness, and frequently with attenuated bodies and/or appendages. The terms troglobitic, stygobitic, stygofauna, troglofauna, and hypogean or hypogeic, are often used for cave-dwelling organisms. A 2012 study by a team from the National University of Singapore found that reductive changes in freshwater cave crabs evolved at the same rate as constructive changes. This shows that both selection and evolution have a role in advancing reductive changes (e.g smaller eyes) and constructive changes (e.g larger claws), making troglomorphic adaptations subject to strong factors that affect an organism's morphology. Troglomorphism occurs in molluscs, velvet worms, arachnids, myriapods, crustaceans, insects, fish, amphibians (notably cave salamanders) and reptiles. To date no mammals or birds have been found to liv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museum Koenig
The Alexander Koenig Zoological Research Museum (German: ''Zoologisches Forschungsmuseum Alexander Koenig'', abbreviated ZFMK) is a natural history museum and zoological research institution in Bonn, Germany. The museum is named after Alexander Koenig, who donated his collection of specimens to the institution. The museum was opened in 1934 and is affiliated with the Leibniz Association. On 1 September 1948 the museum saw the opening of the Parlamentarischer Rat, the organ to create the German constitution. The actual proceedings happened in the nearby Pädagogische Akademie, the later Bundeshaus. History The museum was founded by the private scholar Alexander Koenig (1858–1940) as a private institute for zoological research and public education. Alexander Koenig, who was born in 1858 as the son of the wealthy merchant Leopold Koenig, began to collect birds and mammals as a boy. He later studied zoology and received a doctorate in natural history in 1884. In the following yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vietnam
Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland Southeast Asia, with an area of and population of 96 million, making it the world's sixteenth-most populous country. Vietnam borders China to the north, and Laos and Cambodia to the west. It shares maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City (commonly known as Saigon). Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle America (Americas)
Middle America is a subregion in the middle latitudes of the Americas. It usually includes Mexico, the 7 countries of Central America, and the 13 island countries and 18 territories of the Caribbean. Together with Northern America, they form the continent of North America. Colombia and Venezuela of South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while Bermuda and The Guianas are infrequently included. Geography Physiographically, Middle America marks the territorial transition between Northern America and South America, connecting yet separating the two.Gonzalez, Joseph. 2004"Middle America: Bridging Two Continents"(ch. 17).

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Commensalism
Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; parasitism, where one is harmed and the other benefits, and parasitoidism, which is similar to parasitism but the parasitoid has a free-living state and instead of just harming its host, it eventually ends up killing it. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fishes.
