How Do Elephant Nose Fish Use Electricity? Elephant-nose fish are in the family Mormyridae, and are known as weakly electric fish. They move slowly through murky streams and lakes in Africa, using an electrosensory system to detect the minute electrical pulses emitted by their invertebrate prey.
How do elephant nose fish produce electricity? Over half of all vertebrates are fish. Elephantnose fish solve this problem by navigating their environment with an electric sense. Modified muscle cells near the fish’s tail act as an electric organ that emits electric signals and generates a weak electric field around the fish.
What does the elephant nose fish use to sense its prey? As an electric fish, the elephant-nose fish has two specialized systems that help it sense its surroundings — a passive system attuned to the minute electric signatures of everything living in its environment, including prey, and an active system that voluntarily emits brief pulses of electricity.
Are elephant nose fish smart? With its tiny brain (and no cortex), the elephantnose fish (Gnathonemus petersii)* achieves performance comparable to that of humans or other mammals in certain tasks, according to zoologists at the University of Bonn and a colleague from Oxford.
