Mormyromast, a type of electroreceptor found only in mormyrid fishes Further information: Electroreception and electrogenesis Elephantfish possess electric organs that generate weak electric fields , and electroreceptors ( ampullae of Lorenzini , knollenorgans , and Mormyromasts) that detect small variations in these electric fields caused by ...
Bronze figurine of Oxyrhynchus fish, Late Period-Ptolemaic Egypt The Medjed was a sacred fish in Ancient Egypt. At the city of Per-Medjed, better known as Oxyrhynchus, whose name means "sharp-nosed" after the fish, archaeologists have found fishes depicted as bronze figurines, mural paintings, or wooden coffins in the shape of fishes with downturned snouts, with horned sun-disc crowns like ...
Mormyromast, a type of electroreceptor found only in the skin of Mormyrid fishes These fish have two types of tuberous electroreceptor: [ note 2 ] the Knollenorgan [ 43 ] and the Mormyromast . [ 44 ] [ 45 ] Both organs are found in adult individuals, where they are lightly covered by epithelial cells and skin, while their sensitivity ranges ...
The subfamily Mormyrinae contains all but one of the genera of the African freshwater fish family Mormyridae in the order Osteoglossiformes.They are often called elephantfish due to a long protrusion below their mouths used to detect buried invertebrates that is suggestive of a tusk or trunk (some such as Marcusenius senegalensis gracilis are sometimes called trunkfish though this term is ...
Mormyrops is a genus of weakly electric fish in the family Mormyridae from freshwater in Africa. They are characterized by an elongate head measuring twice as long as high, and no teeth on the palate or the tongue. [1]
Mormyrus longirostris, commonly referred as the eastern bottle-nosed mormyrid, is a medium-sized ray-finned fish species belonging to the family Mormyridae. It was originally described by Wilhelm Peters in Monatsberichte der Akad. Wiss. Berlin , 1852.
Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. The Latin name petersii is probably for the German naturalist Wilhelm Peters. The fish uses electrolocation to find prey, and has the largest brain-to-body oxygen use ratio of all known vertebrates (around 0.6). [2]
Hyperopisus is a monospecific genus of freshwater ray-finned fish belonging to the family Mormyridae, the elephantfishes.The only species in the genus is Hyperopisus bebe. [2]
