These fish have villiform (brush-like) teeth on the upper and lower jaws. The snout is relatively short. The eyes are relatively large, with a diameter equal to or greater than the distance between nares. The anal fin originates at the isthmus (the strip of flesh on the ventral surface between the gill covers).
Eigenmannia is a genus of fish in the family Sternopygidae (glass knifefishes) native to tropical and subtropical South America (south to the Río de la Plata Basin), and Panama. [ 1 ] [ 2 ] They are typically found in slow-flowing streams, along the edge of large rivers, in deep river channels and in floodplains, and the genus also includes E ...
The appendix on the body has black lines running through the bottom of the sides, with the most intense line running on the anal fin. Like all members of its order, it is distinguished by its ability to produce electric fields. This is achieved by discharging an electric organ in the tail. [2]
Knifefish may refer to several knife-shaped fishes: The Neotropical or weakly electric knifefishes, order Gymnotiformes, containing five families: Family Gymnotidae (banded knifefishes and the electric eel) Family Rhamphichthyidae (sand knifefishes) Family Hypopomidae (bluntnose knifefishes) Family Sternopygidae (glass and rat-tail knifefishes)
The clown featherback (Chitala ornata), also known as the clown knifefish and spotted knifefish, is a nocturnal species of tropical fish with a long, knife-like body. This knifefish is native to freshwater habitats in Cambodia, China, Hong Kong, Laos, Macau, Thailand, and Vietnam, [2] but it has also been introduced to regions outside its native range. [1]
Kryptopterus vitreolus is a small, transparent-bodied, freshwater-dwelling catfish with two long sensory barbels. Standard lengths for mature fish may range up to 8 cm (3.1 in), but usually only reach around 6.5 cm (2.6 in) in total length. [2] Their bodies are transparent because, like all catfish, they lack scales.
English: Electroreception of capacitative and resistive objects in glass knifefish. The fish emits a continuous wave from its electric organ; the signal detected by its electroreceptors is modified by the electrical properties of the objects around it.
The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, cranchiid, cranch squid, or bathyscaphoid squid. [2] Cranchiid squid occur in surface and midwater depths of open oceans around the world. They range in mantle length from 10 cm (3.9 in) to over 3 m (9.8 ft), in the case of the colossal ...
