Peters' elephant-nose fish ("
petersii"; syn. "
brevicaudatus" Pellegrin, 1919, "Mormyrus petersii" Günther, 1862) is an African freshwater elephantfish in the genus "
". Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. As the Latin name "petersii" confirms it is named after someone called "Peters" (probably Wilhelm Peters), although the apostrophe is often misplaced and the common name given as "Peter's elephantnose fish". It uses electrolocation to find prey, and has the largest brain-to-body oxygen use ratio of all known vertebrates (around 0.6).
The blunt-jawed elephantnose, "
tamandua", is an elephantfish in the genus "
". Other names in English include worm-jawed mormyrid. It is found in murky waters in West Africa. The fish is brown or black with a long elephant-like snout and the mouth is located near the end of this probiscis. Its diet consist of worms, small fish, and insects.
The most common fish species of Lake Chilwa are Barbus paludinosus, Oreochromis shiranus chilwae, Clarias gariepinus, Alestes (or Brycinus) imberi and
The longnose stonebasher ("
longibarbis") is a species of fish in the Mormyridae family. It is found in Burundi, the Democratic Republic of the Congo, Kenya, and Tanzania. Its natural habitats are rivers, freshwater lakes, freshwater marshes, and inland deltas.
The EOD waveform takes two general forms depending on the species. In some species the waveform is continuous and almost sinusoidal (for example the genera "Apteronotus", "Eigenmannia" and "Gymnarchus") and these are said to have a wave-type EOD. In other species, the EOD waveform consists of brief pulses separated by longer gaps (for example "
", "Gymnotus", "Leucoraja") and these are said to have a pulse-type EOD.
The non-cichlid native fish include African tetras ("Brycinus"), cyprinids ("Enteromius", "Garra", "Labeo", "Labeobarbus", "Rastrineobola" and "Xenobarbus"), airbreathing catfish ("Clariallabes", "Clarias" and "Xenoclarias"), bagrid catfish ("Bagrus"), loach catfish ("Amphilius" and "Zaireichthys"), silver butter catfish ("Schilbe intermedius"), "Synodontis" squeaker catfish, "Nothobranchius" killifish, poeciliids ("Aplocheilichthys" and "Micropanchax"), the spiny eel "Mastacembelus frenatus", elephantfish ("
", "Hippopotamyrus", "Marcusenius", "Mormyrus", "Petrocephalus", and "Pollimyrus"), the climbing gourami "Ctenopoma muriei" and marbled lungfish ("Protopterus aethiopicus").
Weakly electric fish generate a discharge that is typically less than one volt in amplitude. These are too weak to stun prey and instead are used for navigation, object detection (electrolocation) and communication with other electric fish (electrocommunication). Two of the best-known and most-studied examples are Peters' elephantnose fish ("
petersi") and the black ghost knifefish ("Apteronotus albifrons"). The males of the nocturnal "Brachyhypopomus pinnicaudatus", a toothless knifefish native to the Amazon basin, give off big, long electric hums to attract a mate.
