Heteropoda Maxima
The giant huntsman spider (''Heteropoda maxima'') is a species of the huntsman spider family ''Sparassidae'' found in Laos. It is considered the world's largest spider by leg span, which can reach up to . Description The colouration is yellowish-brown with several irregularly distributed dark spots on the rear half. The legs have wide dark bands before the first bend. Like all huntsman spiders, the legs of the giant huntsman spider are long compared to the body, and twist forward in a crab-like fashion. Apart from its size, the ''H. maxima'' can be distinguished from other species of ''Heteropoda'' by genital characteristics. On males, the cymbium is at least three times longer than the tegulum. The female is distinguished by a characteristically shaped epigyneal field with two anterior directed bands, and the course of their internal ducts. The giant huntsman spider is the largest member of the family Sparassidae, boasting a leg-span, and body-length. The largest known mem ...

Peter Jäger
Peter Jäger is a German people, German arachnologist, and current Head of Arachnology at the Naturmuseum Senckenberg, Senckenberg Research Institute and Natural History Museum in Frankfurt, Germany. He has named several spiders after celebrities; in 2008, he named ''Heteropoda davidbowie'' after British singer David Bowie, and ''Heteropoda ninahagen'' after German singer Nina Hagen. In 2013, he named ''Bowie monaghani, Ctenus monaghani'' (currently in the genus ''Bowie (spider), Bowie'') after actor Dominic Monaghan, to honor his work in the documentary series ''Wild Things with Dominic Monaghan''. In 2020, Jäger named a new genus and species of huntsman spiders from Madagascar after Greta Thunberg. The new spider is named ''Thunberga greta''. In 2022, he named 54 species of huntsman spiders from across Asia under the new genus ''Bowie (spider), Bowie'' in commemoration of the musician David Bowie 75th's birthday, the second time the musician's name was honored.

Cerbalus Aravaensis
''Cerbalus aravaensis'' is a huntsman spider found in the southern Arava Valley of Israel and Jordan. The species was first described by Gershom Levy of the Hebrew University of Jerusalem in 2007, though news agencies later reported it in 2010 as a new discovery (with a slightly different spelling) by a team of biologists from the University of Haifa. The spider has a leg span of , making it the largest member of the family Sparassidae in the Middle East. Males have a body length of , while females' body length is . Habitat ''Cerbalus aravaensis'' lives in sand dunes, and partly stable sands at the edge of salt marshes. It is nocturnal and is most active in the hotter summer months. It constructs underground dens with hinged, trap-door like operculum made of sand and glue, in order to disguise the entrance from predators. Conservation The Sands of Samar, the last remaining sand dunes in the southern Arava region of Israel and home to ''Cerbalus aravaensis'', are disappearing ...

Endemic Fauna Of Laos
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolarachne
''Mongolarachne'' is an extinct genus of spiders placed in the monogeneric family Mongolarachnidae. The genus contains only one species, ''Mongolarachne jurassica'', described in 2013, which is presently the largest fossilized spider on record. The type species was originally described as ''Nephila jurassica'' and placed in the living genus ''Nephila'' which contains the golden silk orb-weavers. Subsequently it was determined to be stem-orbicularian, i.e. a relative of the group Orbiculariae, which contains the family Nephilidae, but also several other families, such as Theridiidae, Theridiosomatidae or Uloboridae. The species is known only from the Middle Jurassic Jiulongshan Formation, part of the Daohugou Beds, near the village of Daohugou in Ningcheng County, northeastern China and the Yixian Formation. A second putative species, '' Mongolarachne chaoyangensis'', was described in 2019, but it was subsequently shown to be a forgery based on a fossil crayfish. Jorg W ...

Goliath Birdeater
The Goliath birdeater (''Theraphosa blondi'') belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass () and body length (up to ), and second to the giant huntsman spider by leg span. It is also called the Goliath tarantula or Goliath bird-eating spider; the practice of calling theraphosids "bird-eating" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one eating a hummingbird. Despite the spider's name, it rarely preys on birds. Physical description These spiders can have a leg span up to , a body length of up to and can weigh up to .Goliath Bird-Eating Spider , Arkive Birdeaters are one of the few tarantula species that lack tibial spurs, located on the first pair of legs of mos ...

Latrodectus
''Latrodectus'' is a broadly distributed genus of spiders with several species that are commonly known as the true widows. This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders. However, the diversity of species is much greater. A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows" (southern black widow ''Latrodectus mactans'', western black widow ''Latrodectus hesperus'', and northern black widow ''Latrodectus variolus''). Besides these, North America also has the red widow ''Latrodectus bishopi'' and the brown widow ''Latrodectus geometricus'', which, in addition to North America, has a much wider geographic distribution. Elsewhere, others include the European black widow (''Latrodectus tredecimguttatus''), the Australian redback black widow (''Latrodectus hasseltii'') and the closely related New Zealand katipō (''Latrodectus katipo''), several differ ...

Greater Mekong Subregion
The Greater Mekong Subregion, (GMS) or just Greater Mekong, is a trans-national region of the Mekong River basin in Southeast Asia. The region is home to more than 300 million people. It came into being with the launch of a development program in 1992 by the Asian Development Bank that brought together the six Asian countries of Cambodia, China (specifically Yunnan Province and the Guangxi Zhuang Autonomous Region), Laos, Myanmar (Burma), Thailand, and Vietnam. The Greater Mekong holds irreplaceable natural and cultural riches and is considered one of the world's most significant biodiversity hotspots. The region is an important food provider and the site of many large-scale construction projects with social and economic implications. Regional cooperation For more than two decades, the six countries of the Greater Mekong Subregion have been working together under an economic cooperation program to realize their vision of a prosperous, integrated, and harmonious subregion.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparassidae
Huntsman spiders, members of the family Sparassidae (formerly Heteropodidae), are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places (forests, mine shafts, woodpiles, wooden shacks). In southern Africa the genus ''Palystes'' are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related. More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas. Several species of huntsman spider can use an unusual form of locomotion. The wheel spider (''Carparachne aureoflava'') from the Namib uses a cartwheeling motion which gives it its name, while ''Cebrennus rechenbergi ...
