Lepidophagy
Lepidophagy is a specialised feeding behaviour in fish that involves eating the scales of other fish. Lepidophagy is widespread, having evolved independently in at least five freshwater families and seven marine families. A related feeding behavior among fish is pterygophagy: feeding on the fins of other fish. Species Lepidophagy, or scale-eating, has been reported in a range of fish, including: '' Chanda nama'' (family Ambassidae), '' Plagiotremus'' (family Blenniidae), ''Terapon jarbua'' (family Terapontidae), a few '' Ariopsis'' and '' Neoarius'' species (family Ariidae), '' Pachypterus khavalchor'' (family contentious - variably in Schilbeidae, Bagridae, or Horabagridae), '' Macrorhamphoides uradoi'' (family Triacanthodidae), several pencil catfish (family Trichomycteridae), some piranha, '' Exodon paradoxus'', '' Probolodus'', '' Roeboides'' and '' Roeboexodon'' species (order Characiformes), '' Cyprinodon desquamator'' (family Cyprinodontidae), along with both '' Perissodu ...

Trichomycteridae
Trichomycteridae is a family of catfishes commonly known as pencil catfishes or parasitic catfishes. This family includes the candiru fish (''Vandellia cirrhosa''), feared by some people for its alleged habit of entering into the urethra of humans. They are one of the few parasitic chordates. Another species is the life monsefuano (''Trichomycterus punctulatus'') which was important to the Moche culture and still an important part of Peruvian cuisine.FondazioneslowfoodLife monsefuano.Retrieved 28 April 2017. This family is prohibited from being imported into various parts of the United States. Taxonomy The Trichomycteridae comprise about 42 genera and 286 species described. It is the second-most diverse family of the superfamily Loricarioidea. Numerous species still remain undescribed, such as the human-biting candiru. The monophyly of Trichomycteridae is well-supported. The family is divided into eight subfamilies. The only subfamily that is not monophyletic is th ...

Chanda Nama
The elongate glassy perchlet (''Chanda nama'') is a species of freshwater fish in the Asiatic glassfish family Ambassidae, the only species in the genus ''Chanda''. It is native to an area of south Asia from Pakistan to Burma, in the Indomalayan realm. The elongate glassy perchlet reaches a maximum total length of . The species inhabits canals, ponds, streams, and flooded rice paddies, in both fresh and brackish water, and is found in particular abundance during the rainy season. The species feeds on mosquito larvae and worms and also eats the scales of other fishes (lepidophagy), the species may have potential use in controlling malaria and parasites. The fish are harvested and sold for food in local markets. Several other species of family Ambassidae were formerly classified in genus ''Chanda,'' including the well-known Indian glassy fish, ''Parambassis ranga'', the "glassfish" of the aquarium trade; and the highfin glassy perchlet, ''Parambassis lala'', once considered t ...

Feeding
Eating (also known as consuming) is the ingestion of food. In biology, this is typically done to provide a heterotrophic organism with energy and nutrients and to allow for growth. Animals and other heterotrophs must eat in order to survive – carnivores eat other animals, herbivores eat plants, omnivores consume a mixture of both plant and animal matter, and detritivores eat detritus. Fungi digest organic matter outside their bodies as opposed to animals that digest their food inside their bodies. For humans, eating is more complex, but is typically an activity of daily living. Physicians and dieticians consider a healthful diet essential for maintaining peak physical condition. Some individuals may limit their amount of nutritional intake. This may be a result of a lifestyle choice: as part of a diet or as religious fasting. Limited consumption may be due to hunger or famine. Overconsumption of calories may lead to obesity and the reasons behind it are myriad, however, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schilbeidae
Schilbeidae is a family of catfishes native to Africa and Asia. These fish tend to swim in open water. Schilbid catfishes usually have dorsal fins with a short base and a spine, but '' Parailia'' lack a dorsal fin altogether. Most species also possess an adipose fin. The base of the anal fin is very long. There are usually four pairs of barbels. Several species lack anal fin Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported o ...s. The family name is sometimes spelled Schilbidae in scientific literature.

Cyprinodon Desquamator
''Cyprinodon desquamator'' is a scale-eating species of pupfish in the genus ''Cyprinodon''. It is endemic to hypersaline interior lakes on San Salvador Island, Bahamas. It coexists alongside two other closely related ''Cyprinodon'' species '' C. brontotheroides'' and '' C. variegatus''. Together, these three species represent a recent adaptive radiation, each having moved into a difference niche within their specialized environment. Each of these species are defined by distinct trophic adaptations that have affected various aspects of their functional morphology, behavior, strike kinematics, and reproductive coloration. ''Cyprinodon desquamator'' has enlarged adductor muscles, a small in-lever to out-lever ratio for rapidly closing its large lower jaw, and an elongated body for quickly performing scale-removing strikes on ''Cyprinodon'' and ''Gambusia'' species. This species spawns during the spring and summer, although it appears to be commoner in the summer. The males guard b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Characiformes
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Probolodus
''Deuterodon'' is a genus of characins from river basins in southern and southeastern Brazil (Rio Grande do Sul to Espírito Santo), with a single species of uncertain taxonomic status, ''D. potaroensis'', from Guyana. These are small fish that reach up to in total length. They are omnivores with a specialized mouth structure that allows them to scrape algae and debris off bedrock. Species formerly considered members of the genera ''Probolodus'' and ''Myxiops'' were considered to be members of ''Deuterodon'' by modern researchers, following a thorough phyletic review of several characid genera in 2020, though '' Myxiops'' was revalidated later. Species The following 22 species are recognized in the genus ''Deuterodon'': * '' Deuterodon burgerai'' (Zanata & Camelier, 2009) * '' Deuterodon giton'' (Eigenmann, 1908) * '' Deuterodon hamatilis'' (Camelier & Zanata, 2014) * '' Deuterodon hastatus'' (Myers, 1928) * '' Deuterodon heterostomus'' (Eigenmann, 1911) * '' Deuterodon iguape ...

Exodon Paradoxus
The bucktooth tetra (''Exodon paradoxus'') is the only member of the genus ''Exodon'' and is a freshwater fish of the characin family (family Characidae) of order Characiformes. It is native to the Amazon Basin and Guyana. Though first described in 1845, it was not imported and distributed by the aquarium trade until 1932. This species has a typical elongated tetra appearance; it is light tan in colour with two distinct black spots (one before the tail and another below the dorsal fin). The dorsal fin is bright red. The appellation "bucktooth" does not describe the fish's appearance, since Bucktooth tetras show no signs of having teeth. It grows to a maximum overall length of approximately 12 cm (4.7 in). The fish's natural diet consist of small invertebrates, other fish, and plants. It is not a safe tank mate for fellow tetras, because it will eat small fish, nor is it a safe tank mate for larger species, because it is a notorious lepidophage. Bucktooth tetra are b ...

Piranha
A piranha (, or ; ) is any of a number of freshwater fish species in the subfamily Serrasalminae, of the family Serrasalmidae, in the order Characiformes. These fish inhabit South American rivers, floodplains, lakes and reservoirs. Although often described as extremely predatory and mainly feeding on fish, their dietary habits vary extensively, and they will also take plant material, leading to their classification as omnivorous. Etymology The name originates from Old Tupi '' pirãîa'', being first attested in the 1587 treatise ' by Portuguese explorer Gabriel Soares de Sousa. ''Piranha'' first appears in 1869 in English literature, likely borrowed from Portuguese. Taxonomy and evolution Piranhas belong to the family Serrasalmidae, which includes closely related omnivorous fish such as pacus. Traditionally, only the four genera '' Pristobrycon'', '' Pygocentrus'', '' Pygopristis'', and '' Serrasalmus'' are considered to be true piranhas, due to their specialized teeth. H ...
