Hippopotamyrus is a genus of elephantfish in the family Mormyridae.
There are currently 11 recognized species in this genus: [1] [2]
Some of the species within this genus have rather restricted distribution. For example, H. longilateralis occurs only in the Kunene River of southern Africa. [3]
The Mormyridae, sometimes called "elephantfish", are a superfamily of weakly electric 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 have a large brain size and unusually high intelligence.
Gnathonemus is a genus of elephantfish in the family Mormyridae.
Graham's stonebasher is a species of ray-finned fish in the family Mormyridae. It is found in Kenya, Rwanda, Tanzania, and Uganda. Its natural habitats are rivers, swamps, freshwater lakes, freshwater marshes, and inland deltas. It is threatened by habitat loss.
Marcusenius is a genus of the elephantfish group 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 ray-finned fish in the family Mormyridae. They are weakly electric, enabling them to navigate, to find their prey, and to communicate with other electric fish.
The dark stonebasher is a species of ray-finned 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.
Brienomyrus is a genus of small elephantfish in the family Mormyridae from Africa. Usually available in the pet trade, these fish are commercially referred to as baby whales or baby whalefish.
Campylomormyrus is a genus of elephantfish in the family Mormyridae.
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).
Ivindomyrus is a genus of elephantfishes native to rivers in Middle Africa.
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.
Paramormyrops is a genus of elephantfish in the family Mormyridae from Africa.
Petrocephalus is a genus of ray-finned 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.
The Mormyroidea are a superfamily of fresh water fishes endemic to Africa that, together with the families Hiodontidae, Osteoglossidae, Pantodontidae and Notopteridae, represents one of the main groups of living Osteoglossiformes. They stand out for their use of weak electric fields, which they use to orient themselves, reproduce, feed, and communicate.
