Elephantfish

The family Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), native to Africa.

These fish are also known for having large brain size and unusually high intelligence.

Elephantfishes possess electric organs and are thus notable for their ability to generate weak electric fields that allow the fishes to sense their environment in turbid waters where vision is impaired by suspended matter.

The generation of these electric fields and their use in providing the fishes with additional sensory input from the environment is the subject of considerable scientific research, as is research into communication between and within species.

Elephantnose fish are usually found in murky waters. Although it would be difficult for us to find our way around in their preferred habitat, these fish have developed a special sense that helps them see.
