Paramormyrops is a genus of elephantfish in the family Mormyridae from Africa.
There are currently 11 recognized species in this genus: [1] [2]
Sarotherodon is a genus of oreochromine cichlids that are native to the northern half of Africa, with a single species, S. galilaeus, also ranging into the Levant. A couple of species from this genus have been introduced far outside their native range, and are important in aquaculture. Most other species have small ranges and some are seriously threatened. They mainly inhabit fresh and brackish water, but a few can live in salt water. Species in this genus, as well as those in several other oreochromine and tilapiine genera, share the common name "tilapia" and historically they were included in the genus Tilapia.
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 freshwater ray-finned fishes belonging to the family Mormyridae, the elephantfishes. The fishes in this genus are found in subsaharan Africa.
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.
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.
Boulengeromyrus is a monospecific genus of freshwater ray-finned fish belonging to the family Mormyridae, the elephantfishes. The only species in the genus is Knoepffler's elephantfish. It occurs only in the Ivindo River and the Ntem River basins of Gabon and Cameroon. It reaches a maximum length of about 41 cm (16 in).
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.
Ivindomyrus is a genus of freshwater ray-finned fish belonging to the family Mormyridae, the elephantfishes. These fishes are found in 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 hopkinsi is a species of freshwater electric fish. It was discovered in the Ivindo River in Gabon, in west-Central Africa by Dr. Carl D. Hopkins of Cornell University. It is distributed throughout the Ivindo River basin of Gabon and the Ntem River basin of Cameroon. Described originally as a Brienomyrus in 1985 it was transferred to Paramormyrops in 2007. The electric discharge has two phases: a head-positive phase followed by a head-negative phase. The mean duration of the EOD is 2.8 ms for females, 2.96 for males. The Fourier transform of the EOD peaks at 536 Hz for females, 468 for males. Both male and female EODs have a head-negative voltage bump about 5 to 6 ms after the main head positive phase (arrows).
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.
Coptodon is a genus of cichlids native to fresh, brackish and coastal marine waters in Africa with C. zillii also found in the Middle East. It is the only genus in the tribe Coptodonini. Formerly included in Tilapia, this genus and tribe was separated in 2013. Despite the change in genus, Coptodon spp. are still referred to by the common name tilapia. Several species are important in local fisheries and a few are aquacultured.
Cryptomyrus is a genus of mormyrid fish native to Gabon.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
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.
