Hugh M
Hugh is the English-language variant of the masculine given name , itself the Old French Old French (, , ; ) was the language spoken in most of the northern half of France approximately between the late 8th Hugo'', a short form of Continental Germanic Germanic name, given names beginning in the element "mind, spirit" (Old English ). The Germanic name is on record beginning in the 8th century, in variants ''Chugo, Hugo, Huc, Ucho, Ugu, Uogo, Ogo, Ougo,'' etc. The name's popularity in the Middle Ages ultimately derives from its use by Franks, Frankish nobility, beginning with Duke of the Franks and Count of Paris Hugh the Great (898–956). The Old French form was adopted into English from the Norman England, Norman period (e.g. Hugh of Montgomery, 2nd Earl of Shrewsbury d. 1098; Hugh d'Avranches, 1st Earl of Chester, d. 1101). The spelling ''Hugh'' in English is from the Picard variant spelling ''Hughes (given name), Hughes'', where the orthography ''-gh-'' takes the role ...

Tropical Fish
Tropical fish are fish found in aquatic tropical environments around the world. Fishkeepers often keep tropical fish in freshwater and saltwater aquariums. The term "tropical fish" is not a taxonomic group, but rather is a general term for fish found in such environments, particularly those kept in aquariums. Aquarium fish Tropical fish is a term commonly used to refer to fish that are kept in heated aquariums. Freshwater tropical fish are more commonly kept than saltwater tropical fish due to the common availability of fresh water sources, such as tap water, whereas salt water is not commonly available and has to be recreated by using fresh water with sea salt additions. Salt water has to be monitored to maintain the correct salinity because of the effects of evaporation. Freshwater tropical aquariums can be maintained by simply topping up with fresh water. Tropical fish are popular choices for aquariums due to their often bright coloration, which typically derives from b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danio
''Danio'' is a genus of small freshwater fish in the family (biology), family Cyprinidae found in South Asia, South and Southeast Asia, commonly kept in aquarium, aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbel (anatomy), barbels. Species of this genus consume various small aquatic insects, crustaceans and worms. Taxonomy The name ''"danio"'' comes from the Bengali language, Bangla name ''dhani'', meaning "of the rice field". ''Danio'' was described in the early 19th century by Francis Buchanan-Hamilton, 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.

Danionidae
The danionins are a group of small, minnow-type fish belonging to the family Danionidae. Species of this group are in the genera clades ''Danio'' and '' Devario'' (which also includes ''Chela'', ''Laubuka'', ''Microdevario'', and ''Microrasbora'' genera), based on the latest phylo-genetic research by Fang et al in 2009. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Fishes of the ''danio'' clade tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Species within the ''devario'' clade tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.

Langkawi
Langkawi, officially known as Langkawi, the Jewel of Kedah (), is a duty-free island and an archipelago of 99 islands (plus five small islands visible only at low tide in the Strait of Malacca) located some 30 km off the coast of northwestern Malaysia and a few kilometres south of Ko Tarutao, adjacent to the Thailand, Thai border. Politically, it is an administrative list of districts in Malaysia, district of Kedah, with Kuah as its largest town. Langkawi was developed as a tourist destination in the 1980s, and Pantai Cenang is the island's most popular beach and tourist area. Etymology The name ''Langkawi'' is thought to have existed by the early 15th century, although in the 16th century the island of Langkawi was also marked on maps variously as Langa, Langka, Lansura, and Langapura. There are many suggestions for the origin of the name of Langkawi. According to one interpretation, ''Langkawi'' means island of the reddish-brown eagle, a Brahminy kite in colloquial M ...

Tail
The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso. In vertebrate animals that evolution, evolved to lose their tails (e.g. frogs and hominid primates), the coccyx is the homologous vestigial of the tail. While tails are primarily considered a feature of vertebrates, some invertebrates such as scorpions and springtails, as well as snails and slugs, have tail-like appendages that are also referred to as tails. Tail-shaped objects are sometimes referred to as "caudate" (e.g. lobes of liver#Caudate lobe, caudate lobe, caudate nucleus), and the body part associated with or proximal to the tail are given the adjective "caudal (anatomical term), caudal" (which is considered a more precise anatomical terminology). Function Animal tails are used in a variety of ways. They provide a source of thrust for aquatic locomotion for fish, cetaceans and cr ...

Gill
A gill () is a respiration organ, respiratory organ that many aquatic ecosystem, aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (: branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamella (surface anatomy), lamellae (folds) contain blood or Coelom#Coelomic fluid, coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including Mollusc, molluscs, crustaceans, insects, fish, a ...

Spawn (biology)
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: * Bony fishes * Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) * Amphibians (such as frogs, toads, salamanders, newts) * Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, birds, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Francis George Kerr
Arthur Francis George Kerr (1877–1942) was an Irish medical doctor. He is known particularly now for his botanical work, which was important for the study of the flora of Thailand. He encouraged other botanists to collect plant specimens in Thailand, in particular Emily Collins A number of plant species are named after him, including '' Dipterocarpus kerrii'', '' Hoya kerrii'', '' Loranthus kerrii'', '' Nepenthes kerrii'', ''Platanus kerrii'' and '' Rafflesia kerrii''. Also several plant genus honour his name including '' Kerriochloa'', '' Kerriodoxa'', '' Kerriothyrsus'', and also the genus ''Afgekia'' which is an abbreviation of his names. He also originated some botanical names, for example, the genus name '' Dimetra'' (Oleaceae Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct.Peter S. Gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1931
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 ...
