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.
There are currently three recognized species in this genus: [1] [2]
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.
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. 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.
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 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).
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.
Knoepffler's elephantfish is a species of elephantfish in the family Mormyridae being the only member of its genus. 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).
Campylomormyrus is a genus of elephantfish in the family Mormyridae.
Genyomyrus donnyi is a species of elephantfish in the family Mormyridae being the only member of its genus. It occurs only in the Congo River basin in Middle Africa. It reaches a length of about 45 cm (1.5 ft).
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 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.
