A new study published in Science Advances explores the unique evolutionary processes among certain genes in certain fish species that allowed them to develop electric organs (think: the electric eel).

Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish ...

Research from the University of Adelaide has found that some species of fish will have higher reproductive capacity because of larger sex organs, under the more acidic oceans of the future. "The ...

Scientists have been studying a fish sensory organ to understand cues for collective behavior which could be employed on underwater robots. Scientists, led by University of Bristol, have been studying ...

A new study explains how small genetic changes enabled electric fish to evolve electric organs. The finding might also help scientists pinpoint the genetic mutations behind some human diseases.
