Geosesarma Malayanum
''Geosesarma malayanum'' is a species of small red crab found in Malaysia. It is famous for its relationship with pitcher plants; as such, it is classified as a nepenthephile. ''G. malayanum'' is known to visit ''Nepenthes ampullaria'' plants and raid the pitchers of their contents. It uses its claws to crush and consume the drowned prey. However, the crabs are reportedly trapped by pitchers in Brunei Brunei ( , ), formally Brunei Darussalam ( ms, Negara Brunei Darussalam, Jawi alphabet, Jawi: , ), is a country located on the north coast of the island of Borneo in Southeast Asia.

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 in fresh w ...

Malaysia
Malaysia ( ; ) is a country in Southeast Asia. The federation, federal constitutional monarchy consists of States and federal territories of Malaysia, thirteen states and three federal territories, separated by the South China Sea into two regions: Peninsular Malaysia and Borneo's East Malaysia. Peninsular Malaysia shares a land and maritime Malaysia–Thailand border, border with Thailand and Maritime boundary, maritime borders with Singapore, Vietnam, and Indonesia. East Malaysia shares land and maritime borders with Brunei and Indonesia, and a maritime border with the Philippines and Vietnam. Kuala Lumpur is the national capital, the country's largest city, and the seat of the Parliament of Malaysia, legislative branch of the Government of Malaysia, federal government. The nearby Planned community#Planned capitals, planned capital of Putrajaya is the administrative capital, which represents the seat of both the Government of Malaysia#Executive, executive branch (the Cabine ...

Pitcher Plants
Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar. Types The term "pitcher plant" generally refers to members of the Nepenthaceae and Sarraceniaceae families, but similar pitfall traps are employed by the monotypic Cephalotaceae and some members of the Bromeliaceae. The families Nepenthaceae and Sarraceniaceae are the most species-rich families of pitcher plants. The Nepenthaceae contains a single genus, ''Nepenthes'', containing over 100 species and numerous hybrids and cultivars. In this genus of Old World pitcher plants, the pitchers are borne at the end of tendrils that extend from the midrib of an otherwise unexceptional leaf. Old World pitcher plants are typically characterized as having ...

Nepenthephile
''Nepenthes'' infauna are the organisms that inhabit the pitchers of ''Nepenthes'' plants. These include fly and midge larvae, spiders, mites, ants, and even a species of crab, ''Geosesarma malayanum''. The most common and conspicuous predators found in pitchers are mosquito larvae, which consume large numbers of other larvae during their development. Many of these animals are so specialised that they cannot survive anywhere else, and are referred to as ''nepenthebionts''. The complex relationships between these various organisms are not yet fully understood. The question of whether infaunal animals "steal" food from their hosts, or whether they are involved in a mutually beneficial (symbiotic) association has yet to be investigated experimentally and is the source of considerable debate. Charles Clarke suggests that mutualism is a "likely situation", whereby "the infauna receives domicile, protection and food from the plant, while in return, the infauna helps to break ...

Nepenthes Ampullaria
''Nepenthes ampullaria'' (; Latin ''ampulla'' meaning "flask") is a very distinctive and widespread species of tropical pitcher plant, present in Borneo, the Maluku Islands, New Guinea, Peninsular Malaysia, Singapore, Sumatra, and Thailand.McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole. Catalano, M. 2010. '' Nepenthes della Thailandia: Diario di viaggio''. Prague.McPherson, S.R. & A. Robinson 2012. '' Field Guide to the Pitcher Plants of Peninsular Malaysia and Indochina''. Redfern Natural History Productions, Poole. ''Nepenthes ampullaria'', unlike other members of its genus, has evolved away from carnivory and the plants are partly detritivores, collecting and digesting falling leaf litter in their pitchers.Moran, J.A., C.M.

''Nepenthes of Borneo'' is a monograph by Charles Clarke (botanist), Charles Clarke on the Nepenthes, tropical pitcher plants of Borneo.Clarke, C.M. 1997. ''Nepenthes of Borneo''.

Grapsoidea
The Grapsoidea are a superfamily of crabs; they are well known and contain many taxa which are terrestrial (land-living), semiterrestrial (taking to the sea only for reproduction), or limnic (living in fresh water). Another well-known member with a more conventional lifestyle is the Chinese mitten crab, ''Eriocheir sinensis''. The delimitation of the Grapsidae and Plagusiidae is in need of revision; the latter at least is not monophyletic. The same apparently holds true for several genera in the Sesarmidae. The closest living relatives of the Grapsoidea are the Ocypodoidea The Ocypodoidea, or ocypoid crabs, are a superfamily of crabs, named after the genus '' Ocypode''. It contains over 300 extant species in these eight families: * Camptandriidae Stimpson, 1858 * Dotillidae Stimpson, 1858 * Heloeciidae H. Miln .... In fact, they seem to be paraphyletic with respect to each other and it seems warranted to merge the Ocypodoidea into the Grapsoidea. References Exter ...

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. ...
