Somanniathelphusa Zanklon
''Somanniathelphusa zanklon'' is a species of endangered freshwater crab considered to be endemic to Hong Kong. Ecology and behavior The lifecycle of ''S. zanklon'' is similar to most true freshwater crabs, in which they brood over planktonic larvae, and release their juveniles at the onset of the rainy season. It is naturally omnivorous, with records of it eating seeds of the '' Bauhinia variegata'' tree, as well as various species of freshwater snails. It is preyed upon by both native wild carp, as well as invasive goldfish and tilapia, which have been introduced to their environment through human intervention. Habitat and range It prefers living in slow moving streams or lowland marshes, was originally described from specimens from the lower Lam Tsuen River and the So Kwun Wat area of Hong Kong. Studies have shown that is tolerant to organic pollution, and can be found in irrigation ditches around the New Territories The New Territories (N.T., Traditional Chin ...

Freshwater Crab
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight family (biology), families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic crustacean larvae, larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemism, endemic to small areas. As a result, a large proportion are endangered species, threatened with extinction. Systematics More than 1,300 species description, described species of freshwater crabs are known, out of a total of 6,700 species of crabs across all environments. The total number of species of freshwater crabs, including undescribed species, is thought to be up to 65% higher, potentially up to 2,155 species, although most of the additional species are currently unknown to science. They belong to eight families, each with a limited distribution, although various crabs from other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hong Kong
Hong Kong)., Legally Hong Kong, China in international treaties and organizations. is a special administrative region of China. With 7.5 million residents in a territory, Hong Kong is the fourth most densely populated region in the world. Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War. The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained a 99-year lease of the New Territories in 1898. Hong Kong was occupied by Japan from 1941 to 1945 during World War II. The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems. Originally a sparsely populated area of farming and fishing villages,. the territory is now one of the world's most signific ...

Plankton
Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. fresh water, Freshwater plankton are similar to marine plankton, but are found in lakes and rivers. Mostly, plankton just drift where currents take them, though some, like jellyfish, swim slowly but not fast enough to generally overcome the influence of currents. Although plankton are usually thought of as inhabiting water, there are also airborne versions that live part of their lives drifting in the at ...

Wet Season
The wet season (sometimes called the rainy season or monsoon season) is the time of year when most of a region's average annual rainfall occurs. Generally, the season lasts at least one month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M. Benders-Hyde (2003)World Climates.Blue Planet Biomes. Retrieved on 2008-12-27. Some areas with pronounced rainy seasons will see a break ...

Bauhinia Variegata
''Bauhinia variegata'' is a species of flowering plant in the legume family, Fabaceae. It is native to an area from China through Southeast Asia to the Indian subcontinent. Common names include orchid tree (though not belonging to the family Orchidaceae) and mountain ebony. Description ''Bauhinia variegata'' is a small to medium-sized tree growing to tall and in diameter, deciduous in the dry season. The leaves are obcordate shaped, long and broad, rounded, and bilobed at the base and apex. The flowers are conspicuous, bright pink or white, diameter, with five petals. Pollens are elongated, approximately 75 microns in length. The fruit is a seedpod long, containing 10–15 seeds each. The seedpod dries completely on the tree, and when mature begins to twist into a helix or corkscrew shape, (see below), ultimately exploding open—with a very audible "clack"—to deliver its seeds into the environs. The anatomy of the stem was studied by taking transverse section. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpbelly
The sharpbelly or wild carp, sharpbelly, or common sawbelly (''Hemiculter leucisculus''), is a tropical freshwater and brackish water fish belonging to the family Xenocyprididae. It originates in large streams and reservoirs in mainland China, Taiwan, Hong Kong, Korea, and the Amur River basin. It has become established as an exotic species in several other countries, including Iran, Afghanistan, and the former Soviet Union, where it has displaced local species. It was originally described as ''Culter leucisculus'' by S. Basilewsky in 1855, and has also been referred to as ''Chanodichthys leucisculus'' and ''Hemiculter leucisculus warpachowskii'' in scientific literature. The fish reaches a size up to long, and is native to fresh and brackish water habitats with a pH of 7.0, a hardness of 15 DH, and a temperature of . It is green-gray on the back, and white in the belly. The bulk of its diet includes zooplankton, insects, crustaceans, algae, and detritus. It is of minor commer ...

Goldfish
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of the order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America and Australia. Native to China, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, where several distinct breeds were developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, oran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nile Tilapia
The Nile tilapia (''Oreochromis niloticus'') is a species of tilapia, a cichlid occurring naturally in parts of Africa (such as its namesake Nile River) and the Levant, though numerous introduced populations exist outside its natural range. This current wide range is caused by its high commercial value as a food fish, where it is marketed as mango fish (not to be confused with the mango tilapia, or ''Sarotherodon galilaeus''), nilotica, or boulti, along with many other names, both local and foreign. Due to its value, the Nile tilapia is widely aquacultured across the world due to its hardiness and a mode of reproduction conducive to mass rearing, namely mouthbrooding, and various attempts have been made to increase production yields, including hybridization with other tilapias. Description The Nile tilapia reaches up to in length, and can exceed . As typical of tilapia, males reach a larger size and grow faster than females. Wild, natural-type Nile tilapias are brown ...

Hong Kong Golf Club
The Hong Kong Golf Club is a private golf club. It is home to the Hong Kong Open, a tournament co-sanctioned by the European and Asian Tours. Founded in 1889 as the Royal Hong Kong Golf Club, the club originally played in Happy Valley, a location shared with many other activities. As the club expanded, the need for a more permanent home was addressed with the building of a small 9-hole course at Deep Water Bay, before the club eventually moved to its current location in Fanling, most of which is leased from the Hong Kong government.Agence France-Presse (7 August 2013)"Elite Hong Kong golf club could be bulldozed for flats" ''Bangkok Post''. According to the club annals, the Deep Water Bay location opened in 1898; and the 18-hole Old Course was completed in 1911. To expand the facility, in 1968, the club negotiated the lease of around 30 acres of land at Beas River with which it expanded the Eden Course into a full 18-hole championship course.
