Macrognathus Zebrinus
''Macrognathus zebrinus'', the zebra spiny eel, is a species of spiny eel endemic to Myanmar, specifically known from the Irrawaddy River, Sittaung River and Salween River and may also occur in Indonesia. It was originally described as ''Mastacembelus zebrinus'' before being moved to the genus ''Macrognathus'' in 1984 and 1986. It is pale brown with deeper color in the back and dusky stripes throughout the body (this is more distinct with the young) and has scales on its snout. In 1888, pioneer ichthyologist Francis Day once noted that he thought ''Macrognathus pancalus'' (although smaller) and ''M. zebrinus'' were one species; he also described it as yellow with vertical blue stripes with striped and spotted fins. It has also been introduced to Singapore and is now an established species, known from four reservoirs Kranji, Lower Peirce Lower may refer to: *Lower (surname) *Lower Township, New Jersey *Lower Receiver (firearms) *Lower Wick Gloucestershire, England See als ...

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbl ...

Kranji Reservoir
Kranji Reservoir (Chinese: 克兰芝蓄水池; ) is a reservoir in the northern part of Singapore, near the Straits of Johor. It was a former freshwater river that flowed out into the sea that was dammed at its mouth to form a freshwater reservoir. It can also be classified as an estuary. The dam has a road bridging the two banks, and now prevents the sea from coming in, and is home to a marsh. The former Kranji River has three main tributaries - Sungei Peng Siang, Sungei Kangkar and Sungei Tengah. Historical Significance Although known as a place for fishing and picnicking, the Kranji Reservoir Park is a historical site. A war memorial plaque tells visitors of the historical and violent past of this place. It was here that the Battle of Kranji took place. The Japanese army invaded Kranji in their plan to take Singapore during the Second World War. Kranji Reservoir Park In 1985 it became permissible to fish in the Kranji Reservoir Park. The Park now has two fishing areas, named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrognathus
''Macrognathus'' is a genus of eel-like fish of the family Mastacembelidae of the order Synbranchiformes. These fish are distributed throughout most of South and Southeast Asia. ''Macrognathus'' species feed on small aquatic insect larvae as well as oligochaetes. Appearance and anatomy Most ''Macrognathus'' species attain in length, but a few surpass this size, with the largest being ''M. aral'' at up to . ''Macrognathus'' are mostly similar to ''Mastacembelus''. However, they differ in a more modified rostrum, which may be slightly to significantly larger and longer than those found in ''Mastacembelus''. This serves not only to find food but also to help gather food. In the aquarium A number of species of this genus are popular aquarium fish. These include the lesser spiny eel, ''Macrognathus aculeatus'', the spotfinned spiny eel, ''Macrognathus siamensis'', as well as others. Species According to FishBase, there are currently 25 recognized species in this genus. Accor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans
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 th ...

Tubifex
''Tubifex'' is a cosmopolitan genus of tubificid annelids that inhabits the sediments of lakes, rivers and occasionally sewer lines. At least 13 species of ''Tubifex'' have been identified, with the exact number not certain, as the species are not easily distinguishable from each other. Reproduction ''Tubifex'' worms are hermaphroditic: each individual has both male (testes) and female (ovaries) organs in the same animals. These minute reproductive organs are attached to the ventral side of the body wall in the celomic cavity. In mature specimens, the reproductive organs are clearly found on the ventral side of the body. Copulation and cocoon formation Although the ''Tubifex'' worms are hermaphrodites, the male and female organs become mature at different times; thus self-fertilization is avoided, and cross-fertilization is encouraged. Two mature ''Tubifex'' worms undergo copulation by joining ventral and anterior surfaces together with their anterior ends pointing opposite d ...

Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lower Seletar Reservoir
Lower Seletar Reservoir (Chinese: 实里达蓄水池下段 ; ms, Takungan Air Seletar Bawah) is a reservoir located in the northern part of Singapore, to the east of Yishun New Town. The reservoir has a surface area of 3.6 km², and a capacity of 9.5 million m³. The mean depth of the reservoir is 2 m, with a maximum depth of 5.5 m. The shoreline length is 14.3 km. History Lower Seletar Reservoir was constructed under the Sungei Seletar/Bedok Water Scheme, completed in 1986. The scheme involved the damming of Sungei Seletar to form Lower Seletar Reservoir, the creation of Bedok Reservoir from a former sand quarry and the construction of Bedok Waterworks. Its unique feature was the construction of nine stormwater collection stations to tap the storm runoffs of the surrounding urbanised catchments. Eight of these collection stations are ponds at Yishun, Tampines, Bedok and Yan Kit. Present In 2004, Public Utilties Board (PUB) allowed sailing at Lower Seletar Reservo ...

Spiny Eel
The name spiny eel is used to describe members of two different families of fish: the freshwater Mastacembelidae of Asia and Africa, and the marine (and generally deep sea) Notacanthidae. Both are so-named because of their eel-like shape and sturdy fin spines. These two families are not related: the Notacanthiformes belong to the Superorder Elopomorpha, whose members are characterized by having leptocephalus larvae. The freshwater Mastacembelids do not share this characteristic and are popular specimens in the aquarium trade Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture. Origins of fishkeeping Fish have .... Mastacembelid Spiny eels originate from three places.
