''Dawkinsia chalakkudiensis'' is a species of cyprinid fish endemic to the Chalakkudy River, Kerala Kerala ( , ) is a States and union territories of India, state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile ..., India in the Western Ghats where it can be found in well-vegetated upper reaches of rivers. This species can reach a length of TL. It resembles the related '' D. denisonii'', but the colours of ''D. chalakkudiensis'' are less intense. This fish along with ''D. denisonii'' is also known as Miss Kerala due to its bright color band and shiny scales. It is endangered by the international pet trade, habitat alteration, fisheries, and invasive fish. The presence of a black marking in the dorsal-fin identifies this species from ''D. denisonii''.

Cyprinid
Cyprinidae is a Family (biology), family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barb (fish), barbs and barbel (fish), barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate, vertebrate animal family overall, with about 1,780 species divided into 166 valid genus, 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 Process (anatomy), bony process of the skull. The ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Chalakkudy River
Chalakudy River or Chalakudy Puzha is the fifth longest river in Kerala, India. The river flows through Thrissur district, Palakkad district and Ernakulam district of Kerala. The total drainage area of the river is 1704 km2. Out of this, 1404 km2 lies in Kerala and the rest in Tamil Nadu. The length of the river is 145.5 km. Though Chalakudy River in strict geological sense is a tributary of the Periyar river, for all practical purposes it is treated as a separate river by Government and other agencies. The river has gained its name since it flows along the banks of the Chalakudy Town, the major settlement along the course of the river. It is perhaps the most unpolluted and pristine river in the state and even in India due to the limited amount of industries and wastage disposal around it. Chalakudy River and its basin area were one of the most affected rivers during the 2018 Kerala floods. Origin Though the river has its origin in the Anamalai region of Tamil ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

Denison Barb
The Denison barb, Denison's barb, Miss Kerala, red-line torpedo barb, or roseline shark (''Dawkinsia denisonii'') is an endangered species of cyprinid fish endemic to the fast-flowing hill streams and rivers of the Western Ghats in India. It is commonly seen in the aquarium trade; pet collection caused it to become endangered and is its single major threat. Physical characteristics The fish is characterized by a torpedo-shaped body with silver scales, a red line running from their snout, through the eye, back towards the middle of the body; and below the red line, a black line that runs the length of the fish to the tail. As they mature, a distinctive green/blue marking on top of the head develops. This species reputedly reaches a length of TL, but typically will only reach . They are active shoaling fishes. The species was described by Francis Day and named after Sir William Denison. Habitat and threats Denison barb is endemic to the Achenkovil, Pamba and Chaliyar river ...

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dawkinsia
''Dawkinsia'' is a genus of cyprinid fishes from freshwater in South India and Sri Lanka. It was split off (i.e., reclassified) from genus '' Puntius'' in 2012. Etymology ''Dawkinsia'' is named after the evolutionary biologist Richard Dawkins in recognition of his "contribution to the public understanding of science, particularly, of evolutionary science". Dawkins describes this as "a great honour". Description Adults typically measure SL. They do not have rostral barbels but might have maxillary barbels. Juveniles have a colour pattern consisting of three black bars on body; this persists to adult stage in some species. Adults have a black, horizontally elongate blotch on the caudal peduncle. Species These are the currently recognized species in this genus: * '' Dawkinsia apsara'' ( Katwate, Marcus Knight, Anoop, Raghavan & Dahanukar, 2020) (mascara barb) * '' Dawkinsia arulius'' ( Jerdon, 1849) (Arulius barb) * '' Dawkinsia assimilis'' (Jerdon, 1849) * '' Dawkinsia aus ...
