Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934 he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men developed a friendship which continued after this trip and Hemingway sent speci ...

Temperament
In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes. Some researchers point to association of temperament with formal dynamical features of behavior, such as energetic aspects, plasticity, sensitivity to specific reinforcers and emotionality. Temperament traits (such as Neuroticism, Sociability, Impulsivity, etc.) are distinct patterns in behavior throughout a lifetime, but they are most noticeable and most studied in children. Babies are typically described by temperament, but longitudinal research in the 1920s began to establish temperament as something which is stable across the lifespan. Definition Temperament has been defined as "the constellation of inborn traits that determine a child's unique behavioral style and the way he or she experiences and reacts to the world." Classification schemes Many classification schemes for tempera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba' ...

Gourami
Gouramis, or gouramies , are a group of freshwater anabantiform fishes that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. All living species show parental care until fry are free swimming: some are mouthbrooders, like the Krabi mouth-brooding betta (''Betta Simplex''), and others, like the Siamese fighting fish (''Betta splendens''), build bubble nests. Currently, about 133 species are recognised, placed in four subfamilies and about 15 genera. The name Polyacanthidae has also been used for this family. Some fish now classified as gouramis were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae. As labyrinth fishe ...

Plecostomus , often incorrectly called "bristlenose pleco"
{{Animal common name ...
Plecostomus, pleco, or plec is the common name of several species of freshwater loricariid catfish commonly sold as aquarium fish. These include: *''Hypostomus plecostomus'' *''Hypostomus punctatus'' *''Pterygoplichthys multiradiatus'' *''Pterygoplichthys pardalis'' *''Panaqolus maccus'' It is also used as part of the common names of various similar species of loricariids. The superficially similar loach Beaufortia kweichowensis is also sometimes known as the "butterfly plec", despite not being closely related to the Loracariidae. See also * Loricariidae * Ancistrus ''Ancistrus'' is a genus of nocturnal freshwater fish in the family Loricariidae of order Siluriformes, native to freshwater habitats in South America and Panama.

Loach (fish)
Loaches are fish of the superfamily Cobitoidea. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidea comprise about 107 genera divided among 9 families. Etymology The name Cobitoidea comes from the type genus, ''Cobitis'', described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. However, its origin predates modern zoological nomenclature and derives from a term used by Aristotle to refer to "small fishes that bury... like the gudgeon." Description Loaches display a wide variety of morphologies, making the group difficult to characterize as a whole using external traits. They range in adult length from the 23 mm (1 in) miniature eel-loach, ''Pangio longimanus'', to the 50 cm (20 in) imperial flower loach, ''Leptobotia elongata'', with the latter weighing up to 3 kg (6.6& ...

Danio
''Danio'' is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms. Taxonomy The name ''"danio"'' comes from the Bangla name ''dhani'', meaning "of the rice field". ''Danio'' was described in the early 19th century by Francis Hamilton. Two of the species included by him in the genus, still remain valid—''D. dangila'' and ''D. rerio''. About a century later (1916) and with many more species described in the meantime, the genus was split; the larger species into ''Danio'' and the smaller species into the genus ''Brachydanio''.Spence, R., Gerlach, G., Lawrence, C. & Smith, C.

Rainbowfish
The rainbowfish or Melanotaeniidae is a family of small, colourful freshwater fish found in northern and eastern Australia, New Guinea (including islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia), Sulawesi and Madagascar. The largest rainbowfish genus, ''Melanotaenia'', derives from the ancient Greek ''melano'' (black) and ''taenia'' (banded). Translated, it means "black-banded", and is a reference to the often striking lateral black bands that run along the bodies of those in the genus ''Melanotaenia''. Characteristics The Melanotaeniidae is characterised by having their distal premaxillary teeth enlarged. They have a compressed body with the two dorsal fins being separated but with only a small gap between them. There are 3–7 spines in the first dorsal fin while the second has 6–22 rays, with the first ray being a stout spine in some species, the anal fin has 10–30 rays and, again, the first may be a stout spine in some species. The lateral line is either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barb (fish)
A barb is one of various ray-finned fish species in a non-phylogenetic group, with members in the family Cyprinidae, and especially the genera ''Barbus'' and '' Puntius'', but many others also. They were formerly united with the barbels in the subfamily Barbinae but that group is paraphyletic with the Cyprininae. If the Labeoninae are recognized as distinct, many small African "barbs" would probably, however, warrant recognition as a new subfamily. The root of the word "barb" is common in cyprinid names of European languages, from the Latin ''barba'' ("beard") (COD): * ''barb'' from Catalan * ''barbi'' from Finnish * ''barbo'' from Spanish * ''barbeau'' from French * ''barbo'' from Italian and many others. This is in reference to the barbels which are prominently seen around the mouth of many "barbs". Genera Genera that contain species with common names including "barb": * '' Barbichthys'' * ''Barbodes'' * ''Barboides'' * ''Barbonymus'' – tinfoil barbs * '' Barbopsis ...

Water Hardness
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.World Health OrganizatioHardness in Drinking-Water 2003 Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of multivalent cations such as calcium and magnes ...

Bala Shark
The bala shark, ''Balantiocheilos melanopterus'', also known as the tricolor shark, tricolor sharkminnow, silver shark, or shark minnow, is a fish of the family Cyprinidae, and is one of the two species in the genus ''Balantiocheilos''. This species is not a true shark, but is commonly so called because of its torpedo-shaped body and large fins. Distribution The bala shark occurs in the Malay Peninsula, Sumatra, and Borneo. Previous records further north in the Mekong and Chao Phraya River is due to confusion with the recently described and possibly extinct '' B. ambusticauda'' (although the presence of any ''Balantiocheilos'' in the Mekong is questionable). Appearance and anatomy These fish have a silver body with black margins on their dorsal, caudal, anal, and pelvic fins. They have big eyes to find and catch their prey. The bala shark will grow to a maximum length of . Habitat and ecology Bala sharks are found in midwater depths in large and medium-sized rivers and lakes. T ...
