On mating and function of associated electric pulses in Clarias macrocephalus (Günther 1864): probing an old puzzle, first posed by Charles Darwin

Shedding light on the function of weak episodic electric emission, the authors propose that the modification of electrogenic structures evolved towards increasing the efficiency of direct bodily impact. As extant clariids exhibit intermediate features between non-electric and strongly electric catfishes, Clarias should be considered a “serviceable transition,” which Charles Darwin deemed a possible intermediate form between these two groups.
