Mormyromast, a type of electroreceptor found only in mormyrid fishes Further information: Electroreception and electrogenesis Elephantfish possess electric organs that generate weak electric fields , and electroreceptors ( ampullae of Lorenzini , knollenorgans , and Mormyromasts) that detect small variations in these electric fields caused by ...
Mormyromast, a type of electroreceptor found only in the skin of Mormyrid fishes These fish have two types of tuberous electroreceptor: [ note 2 ] the Knollenorgan [ 43 ] and the Mormyromast . [ 44 ] [ 45 ] Both organs are found in adult individuals, where they are lightly covered by epithelial cells and skin, while their sensitivity ranges ...

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 (around 0.6). [2]
Mormyrus longirostris, commonly referred as the eastern bottle-nosed mormyrid, is a medium-sized ray-finned fish species belonging to the family Mormyridae. It was originally described by Wilhelm Peters in Monatsberichte der Akad. Wiss. Berlin , 1852.
The Sudd stretches from Mongalla to just outside the Sobat River confluence with the White Nile just upstream of Malakal as well as westwards along the Bahr el Ghazal.The shallow and flat inland delta lies between 5.5 and 9.5 degrees latitude north and covers an area of 500 kilometres (310 mi) south to north and 200 kilometres (120 mi) east to west between Mongalla in the south and Malakal in ...
The Cataracts of the Nile are shallow lengths (or whitewater rapids) of the Nile river, between Khartoum and Aswan, where the surface of the water is broken by many small boulders and stones jutting out of the river bed, as well as many rocky islets. In some places, these stretches are punctuated by whitewater, while at others the water flow is ...
