Answer 1

Answer:

Notably, de Santana's team discovered that E. voltai can discharge up to 860 Volts of electricity -- significantly more than the 650 Volts generated by E. electricus. This makes the species the strongest known bioelectric generator, and may be an adaptation to the lower conductivity of highland waters, he says.
