Francis Talbot Day (2 March 1829 – 10 July 1889) was an army surgeon and naturalist in the Madras Presidency who later became the Inspector-General of Fisheries in British Raj, India and British rule in Burma, Burma. A pioneer ichthyologist, he Species description, described more than three hundred fishes in the two-volume work on ''The Fishes of India''. He also wrote the fish volumes of the Fauna of British India series. He was also responsible for the introduction of trout into the Nilgiri hills, for which he received a medal from the French Acclimatisation society, Societe d'Acclimatation. Many of his fish specimens are distributed across museums with only a small fraction deposited in the British Museum (Natural History Museum, London), an anomaly caused by a prolonged conflict with Albert Günther, the keeper of zoology there. Biography Day was born in Maresfield, East Sussex, the third son of William and Ann Elliott née Le Blanc. The family estate included two thousa ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, 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 (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

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.

Nuptial Tubercles
Nuptial tubercles or breeding tubercles (also called pearl organs or nuptial efflorescence) are noticeable skin roughness or horny nodules that form on male fish during breeding. They are made of keratin, the same material as hair, hooves, and fingernails. Use and description These tubercles are dermal structures present in 15 families of fish belonging to 4 orders of Actinopterygii – Salmoniformes, Gonorhynchiformes, Cypriniformes and Perciformes are used in the courtship and reproduction process. They consist of partially or fully keratinised cells that form in certain regions, used to stimulate females during courtship. Their development is stimulated by hormones secreted by the pituitary and adrenal glands, and is induced shortly before the breeding season and discarded after. In some species, at least, there is a correlation between the level of androgens present in the endocrine system and the volume and complexity of tubercle growth. They normally form on the he ...

Cyprinid Fish Of Asia
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used to identify speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
