The black ghost knifefish, a type of electric creature found in the Amazon basin of South America, has inspired researchers to develop new aquatic technology that could be used to study coral reefs, repair damaged deep-sea oil rigs or investigate sunken ships.
Mechanical Amazonian fish could pave way for highly agile underwater robots.
