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 ...
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 ...

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]
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 ...

The Cornish jack, Mormyrops anguilloides, is a species of weakly electric fish in the family Mormyridae, native to quiet waters in much of Sub-Saharan Africa.The largest species in its family, the Cornish jack is a nocturnal group hunter of smaller fishes, using electricity to locate its prey and communicate with other members of its group.
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.
