Nipponopsalis Abei
Nipponopsalididae is a family of harvestmen with three described species in one genus, ''Nipponopsalis'', which is found in East Asia. Name The genus name ''Nipponopsalis'' is a combination of ''Nippon'', meaning Japan, where the genus was first discovered, and the ending of the harvestman genus ''Ischyropsalis'', which comes from the Greek "psalis" (scissors), referring to the long chelicerae. Description They range in body length from 2.3 to 4.1 mm. The carapace is domed, with a large, low ocularium, and rather large eyes. The pedipalps and legs are very long and slender, and the chelicerae are longer than their body and heavily sclerotized. These chelicerae are superficially similar to those found in some Ischyropsalidioids, although this is a case of convergence. The cheliceral fingers exhibit 2 forms of teeth: narrow diaphanous teeth in the middle, and courser teeth distally. The opisthosoma is generally poorly sclerotized, and the ''corona analis'' is incomplete. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelicerae
The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly to pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, and are used to inject venom into prey or a perceived threat. In ''Pisaurina mira'', also known as the nursery web spider, the chelicerae are utilized to snatch the prey once it becomes within reach, facilitating the "sit-and-wait ambush predator" behavior. Both pseudoscorpions and harvestmen have structures on their chelicerae that are used for grooming (papillae in pseudoscorpions, cheliceral teeth in Opiliones). Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and 3-segmented chelate chelicerae. Jackknife chelicerae The jackknife chelicera is subchelate (with ...

Urup
Urup ( ja, 得撫島, Uruppu-to; russian: Уру́п, Urúp, ain, ウルㇷ゚, Urup) is an uninhabited volcanic island in the Kuril Islands chain in the south of the Sea of Okhotsk, northwest Pacific Ocean. Its name is derived from the Ainu language word for salmon trout. It was formerly known as Company's Land. Geography and climate Urup has a roughly rectangular shape, measuring along its long axis and approximately along its narrow axis. It is the fourth largest of the Kuril Islands, with an area of . The highest point is Gora Ivao at . The strait between Urup and Iturup is known as the Vries Strait, after Dutch explorer Maarten Gerritsz Vries, the first recorded European to explore the area. The strait between Urup and Simushir is known as Bussol Strait, after the French word for "compass", which was the name of one of La Pérouse's vessels. This French mariner explored the area of the Kuril Islands in 1787. Urup consists of four major groups of active or dormant stra ...

Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amami Ōshima
, also known as Amami, is the largest island in the Amami archipelago between Kyūshū and Okinawa. It is one of the Satsunan Islands. The island, 712.35 km2 in area, has a population of approximately 73,000 people. Administratively it is divided into the city of Amami, the towns of Tatsugō, Setouchi, and the villages of Uken and Yamato in Kagoshima Prefecture. Much of the island is within the borders of the Amami Guntō National Park. In 2021, it was listed as part of the serial UNESCO World Heritage Site of Amami-Ōshima Island, Tokunoshima Island, northern part of Okinawa Island, and Iriomote Island. History It is uncertain when Amami Ōshima was first settled. Stone tools indicate settlement in the Japanese Paleolithic period, and other artifacts, including pottery, indicate a constant contact with Jōmon, Yayoi and Kofun period Japan. The island is mentioned in the ancient Japanese chronicle '' Nihon Shoki'' in an entry for the year 657 AD. During the Nara peri ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids. At present, the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvestmen
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Altho ...
