Lepidophage
Lepidophagy is a specialised feeding behaviour in fish that involves eating the Scale (zoology), 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 Fish fin, fins of other fish. Species Lepidophagy, or scale-eating, has been reported in a range of fish, including: ''Chanda nama'' (family (biology), family Ambassidae), ''Plagiotremus'' (family Blenniidae), ''Terapon jarbua'' (family Terapontidae), a few ''Ariopsis (fish), Ariopsis'' and ''Neoarius'' species (family Ariidae), Pachypterus khavalchor (family Pachypteridae), 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 ''Perissodus'' species ...

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 ...

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. The monophyly of Trichomycteridae is well-supported. The family is divided into eight subfamilies. The only subfamily that is not monophyletic is the largest one, Trichomycterinae. A large cla ...

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 bre ... [...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 single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
