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. [1]
Dawkinsia is named after the evolutionary biologist Richard Dawkins in recognition of his "contribution to the public understanding of science, particularly, of evolutionary science". [2] [1] : p.80 Dawkins describes this as "a great honour". [3]
Adults typically measure 8–12 cm (3.1–4.7 in) 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. [1] : p.80
There are currently eleven recognized species in this genus: [4]
Barbus is a genus of ray-finned fish in the family Cyprinidae. The type species of Barbus is the common barbel, first described as Cyprinus barbus and now named Barbus barbus. Barbus is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part.
Puntius is a genus of small freshwater fish in the family Cyprinidae native to South Asia and Mainland Southeast Asia, as well as Taiwan.
The Arulius barb is a tropical cyprinid fish native to the Kaveri River basin of south east India. Other common names include Tamiraparani barb, Silas barb and longfin barb.
Pethia stoliczkana is a fresh water tropical cyprinid fish native to the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Laos, Thailand, China and Sri Lanka.
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.
Barbinae are a subfamily of fish included in the family Cyprinidae. The taxonomy for this group has not been entirely worked out as some genera historically considered within it are still considered incertae sedis with respect to being a member of the family, and may be included here, while others may be moved to other subfamilies.
Dawkinsia filamentosa, the filament barb, or poovali paral is a species of barb. Young fish have barely any color and black spots. They start having more color at three months old. The fish is a swift swimmer. Males are larger than females and they fertilize eggs by swimming into the cloud of eggs. The species is most commonly found in coastal floodplains near the Southwest Indian states of Kerala, Tamil Nadu and Karnataka. This species is also known as blackspot barb.
Labeo dussumieri is fish in genus Labeo known to occur in west-flowing rivers of the Western Ghats. Earlier Sri Lankan population was considered as the same species as L. dussumieri, recent phylogenetic and physiological differences suggest that Sri Lankan population is a distinct species, Labeo heladiva..
Dawkinsia assimilis is a species of ray-finned fish in the genus Dawkinsia. It is endemic to the southern Western Ghats especially to the Southwest Indian states of Karnataka and Kerala. They are known as Mascara Barb. Filament barbs are a group of small freshwater fishes found in the rivers of peninsular India and Sri Lanka. There are nine species known under the genus Dawkinsia. These barbs are popular among aquarium hobbyists as an ornamental fish and are also collected from rivers and bred for trade.
The Dharna barb is a species of ray-finned fish in the genus Puntius. It is endemic to India.
Puntius kelumi is a species of cyprinid fish in the genus Puntius. It is found in Sri Lanka.
The Channa barb, is a species of cyprinid fish endemic to India where it occurs in hill streams in forested areas. This species can reach a length of 19.6 centimetres (7.7 in) TL. This species is also found in the aquarium trade. This species is the only member of its genus.
Dawkinsia singhala is a species of ray-finned fish in the genus Dawkinsia. It is found in Sri Lanka. The genus Dawkinsia is named after evolutionary biologist Richard Dawkins.
Dawkinsia srilankensis, the blotched filamented barb, is a species of ray-finned fish in the genus Dawkinsia. This species is endemic to the Kalu River in Sri Lanka and it is in imminent danger of going extinct due to tailings from upstream mines and potentially also capture for the aquarium trade. It was bred recently in the Dehiwala Zoological Gardens.
Rohan David Pethiyagoda is a Sri Lankan biodiversity scientist, amphibian and freshwater-fish taxonomist, author, conservationist and public-policy advocate.
Pethia is a genus of small freshwater fish in the family Cyprinidae native to South Asia, East Asia and Mainland Southeast Asia. Some species are commonly seen in the aquarium trade. The name Pethia is derived from the Sinhalese "pethia", a generic word used to describe any of several small species of cyprinid fishes. Most members of this genus were included in Puntius, until it was revised in 2012.
Haludaria is a genus of cyprinids native to freshwater habitats in the Western Ghats of India. Originally the genus was named DravidiaPethiyagoda, Meegaskumbura & Maduwage, 2012 which is preoccupied by the dipteran genus DravidiaLehrer, 2010.
Dawkinsia rohani is a species of ray-finned fish in the genus Dawkinsia. It is endemic to the Western Ghats and inhabits the hill streams of Kanyakumari District in Tamil Nadu draining into the Arabian Sea.
Tor malabaricus, the Malabar mahseer, is a fish, a species of mahseer native to southwestern India.
Dawkinsia uttara, the northern filament barb, is a species of freshwater fish belonging to the family Cyprinidae.
