Ivindomyrus is a genus of elephantfishes native to rivers in Middle Africa. [1]
There are currently two recognized species in this genus: [1] [2]
The family Mormyridae, sometimes called "elephantfish", are freshwater fish in the order Osteoglossiformes native to Africa. It is by far the largest family in the order with around 200 species. Members of the family can be popular, if challenging, aquarium species. These fish are also known for having large brain size and unusually high intelligence.
Peters's elephant-nose fish is an African freshwater elephantfish in the genus Gnathonemus. 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", 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.
Gnathonemus is a genus of elephantfish in the family Mormyridae.
Hippopotamyrus is a genus of elephantfish in the family Mormyridae.
Marcusenius is a genus of elephantfishes native to Africa. Its members are highly diverse in size, with the smallest species reaching less than 15 cm (6 in) and the largest more than 1 m (3.3 ft).
Mormyrus is a genus of fish in the family Mormyridae.
Pollimyrus is a genus of elephantfishes native to Africa.
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. The genus includes the largest member of the mormyrid family, the cornish jack at up to 1.5 m (4.9 ft) in length.
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. They can also be called tapirfish.
The Steindachner's Angolan mormyrid is a species of elephantfish in the family Mormyridae being the only member of its genus. It is found only in the coastal river basins in Angola in Africa. It reaches a length of about 10 cm (4 in).
The Bebe mormyrid is a species of elephantfish in the family Mormyridae. It is the only species in its genus and is divided into two subspecies. This species is known from many rivers in the northern half of Africa, ranging from the Senegal to the Nile basin. It reaches a length of 51 cm (20 in).
Henry's mormyrid is a species of freshwater elephantfish in the family Mormyridae and the only member of its genus. It occurs in coastal river basins in West Africa, ranging as far southeast as the Kouilou-Niari River in Middle Africa. It reaches a length of about 29 cm (11 in).
Myomyrus is a genus of elephantfish in the family Mormyridae. Its members reach about 25–30 cm (10–12 in) in length and are restricted to the Congo River Basin in Africa.
Oxymormyrus is a small genus of elephantfish in the family Mormyridae. Its members reach about 25–27 cm (10–11 in) in length and are restricted to the Congo, Campo, Kouilou-Niari, Nyanga and Ogowe river basins in Middle Africa.
Paramormyrops is a genus of elephantfish in the family Mormyridae from Africa.
Petrocephalus is a genus of fish in the family Mormyridae. All the fish species of this genus are endemic to Africa.
Stomatorhinus is a genus of small elephantfish in the family Mormyridae.
Electrocommunication is the communication method used by weakly-electric fish. Weakly-electric fish are a group of animals that utilize a communicating channel that is "invisible" to most other animals: electric signaling. Electric fish communicate by generating an electric field that a second individual receives with its electroreceptors. The fish interprets the message using the signal's frequencies, waveforms, delay, etc. The best studied species are two freshwater lineages- the African Mormyridae and the South American Gymnotiformes. While weakly-electric fish are the only group that have been identified to carry out both generation and reception of electric fields, other species either generate signals or receive them, but not both. Animals that either generate or receive electric fields are found only in wet or aquatic environments due to water's relatively low electrical resistance, compared to other substances. So far, communication between electric fish has been identified mainly to serve the purpose of conveying information such as:
Medjed was a species of the family elephantfish worshipped at Oxyrhynchus in ancient Egyptian religion. These fish were believed to have eaten the penis of the god Osiris after his brother Set had dismembered and scattered the god's body. A settlement in Upper Egypt, Per-Medjed, was named after the fish and is now better known under its Greek name Oxyrhynchus.
Cryptomyrus is a genus of mormyrid fish native to Gabon.
