Geosesarma Larsi
''Geosesarma larsi'' is a species of small land-living highland crab found in western Sarawak, Borneo Borneo (; id, Kalimantan) is the List of islands by area, third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java Isl .... Adults have a carapace width of 12–15 mm and are of a purplish-red colour, which distinguishes them from other ''Geosesarma'' species in Borneo. The species is threatened by the loss of their small habitat. ''Geosesarma larsi'' is named after the German photographer and naturalist Lars Fehlandt, who discovered this species during an expedition in December 2016.

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting " tail" ( abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarawak
Sarawak (; ) is a state of Malaysia. The largest among the 13 states, with an area almost equal to that of Peninsular Malaysia, Sarawak is located in northwest Borneo Island, and is bordered by the Malaysian state of Sabah to the northeast, Kalimantan (the Indonesian portion of Borneo) to the south, and Brunei in the north. The capital city, Kuching, is the largest city in Sarawak, the economic centre of the state, and the seat of the Sarawak state government. Other cities and towns in Sarawak include Miri, Sibu, and Bintulu. As of 2021, the population of Sarawak was estimated to be around 2.45 million. Sarawak has an equatorial climate with tropical rainforests and abundant animal and plant species. It has several prominent cave systems at Gunung Mulu National Park. Rajang River is the longest river in Malaysia; Bakun Dam, one of the largest dams in Southeast Asia, is located on one of its tributaries, the Balui River. Mount Murud is the highest point in the state. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo (; id, Kalimantan) is the List of islands by area, third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The list of divided islands, island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the ...

Sesarmidae
The Sesarmidae are a family of crabs, previously included in the Grapsidae by many authors. Several species, namely in ''Geosesarma'', '' Metopaulias'', and '' Sesarma'', are true terrestrial crabs. They do not need to return to the sea even for breeding. Genera The family contains these genera: *''Aratus'' *'' Armases'' *'' Bresedium'' *'' Chiromantes'' *'' Clistocoeloma'' *'' Contusarma'' *'' Cristarma'' *'' Danarma'' *'' Episesarma'' *'' Fasciarma'' *''Geosesarma'' *'' Guinearma'' *'' Haberma'' *'' Karstarma'' *'' Labuanium'' *'' Leptarma'' *'' Manarma'' *'' Metagrapsus'' *'' Metasesarma'' *'' Metopaulias'' *'' Miersarma'' *'' Migmarma'' *'' Muradium'' *'' Namlacium'' *''Nanosesarma'' *'' Neosarmatium'' *'' Neosesarma'' *'' Orisarma'' *'' Parasesarma'' *''Perisesarma'' *'' Platychirarma'' *'' Pseudosesarma'' *'' Sarmatium'' *'' Scandarma'' *''Selatium'' *'' Sesarma'' *'' Sesarmoides'' *''Sesarmops'' *'' Stelgistra'' *'' Tiomanum'' *'' T ...

Freshwater Crustaceans Of Asia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fr ...

Crustaceans Described In 2018
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, 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 emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their l ...
