Nemacheilus Masyae
The arrow loach (''Nemacheilus masyae'') is a species of ray-finned fish in the genus ''Nemacheilus''. Information ''Nemacheilus masyae'' or the "arrow loach", can be found in a freshwater environment within a benthopelagic depth habitat. They are native to a tropical climate. The average length of the ''Nemacheilus masyae'' as an unsexed male is about . The body of this species is a light colour with dark splotches that can be found on its side. It can be identified by its elongated slim body. The arrow loach is known to be found in the areas of Asia, western Malaysia, Peninsular Thailand, the Meklong, part of the Mae Nam Chao Phraya basins, and the Mekong Basin. It is known to occur in shallow forest rivers and steams. They prefer a slow current of clear to slightly turbid water, with a muddy or sandy bottom. As far as their diet goes, this species feeds on insects, larvae, and invertebrates that live in the water. The females of this species are somewhat larger and of a bigge ...

Hugh McCormick Smith
Hugh McCormick Smith, also H. M. Smith (November 21, 1865 – September 28, 1941) was an American ichthyologist and administrator in the United States Bureau of Fisheries. Biography Smith was born in Washington, D.C. In 1888, he received a Doctor of Medicine from Georgetown University; then, in 1908, a Doctor of Law from the Dickinson School of Law at Dickinson College. He began working for the United States Fish Commission (formally, the United States Commission on Fish and Fisheries) in 1886 as an assistant. He directed the scientific research center there from 1897 to 1903. From 1901 to 1902, he directed the Marine Biological Laboratory at Woods Hole, Massachusetts. At the same time, he was on the faculty at Georgetown, teaching medicine from 1888 to 1902 and histology from 1895 to 1902. From 1907 to 1910, Smith led the scientific party aboard the U.S. Bureau of Fisheries (successor organization of the U.S. Fish Commission) research ship during her two-and-a-half-year exp ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Phraya
The Thai nobility was a social class comprising titled officials (''khunnang'', ) in the service of Thai monarchy, the monarchy. They formed part of a hierarchical social system which developed from the time of the Ayutthaya Kingdom (14th century – 1767), through the Thonburi Kingdom, Thonburi (1767–1782) and early Rattanakosin Kingdom, Rattanakosin (1782 onwards) periods. Reforms by King Chulalongkorn ended the system around the end of the 19th century, though noble titles continued to be granted until the abolition of absolute monarchy in Thailand, abolition of absolute monarchy in 1932. Thailand, Thai noble titles comprise a rank and a title, which denote the holder's post or office. Unlike in European aristocracies, Thai noble titles were not inherited, but individually granted based on personal merit. Nevertheless, familial influence was substantial, and some families were able to accumulate large amounts of wealth and power, especially during the 17th to 19th centuries. H ...

Daphnia
''Daphnia'' is a genus of small planktonic crustaceans, in length. ''Daphnia'' are members of the Order (biology), order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their Saltation (gait), saltatory swimming style resembles the movements of fleas. ''Daphnia'' spp. live in various aquatic environments ranging from acidic swamps to Fresh water, freshwater lakes and ponds. The two most commonly found species of ''Daphnia'' are ''Daphnia pulex, D. pulex'' (small and most common) and ''Daphnia magna, D. magna'' (large). They are often associated with a related genus in the order Cladocera: ''Moina'', which is in the Moinidae group instead of the Daphniidae, and is much smaller than ''D. pulex'' (roughly half the maximum length). Appearance and characteristics The body of a ''Daphnia'' species is usually long, and is divided into Segmentation (biology), segments, although this division is not visible. The hea ...

Artemia
''Artemia'' is a genus of aquatic crustaceans also known as brine shrimp or '' sea monkeys''. It is the only genus in the family Artemiidae. The first historical record of the existence of ''Artemia'' dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. ''Artemia'' populations are found worldwide, typically in inland saltwater lakes, but occasionally in oceans. ''Artemia'' are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity (up to 25%). The ability of the ''Artemia'' to produce dormant eggs, known as cysts, has led to extensive use of ''Artemia'' in aquaculture. The cysts may be stored indefinitely and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans ...

Fish Described In 1933
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
