The reason why Ankang fish can live in the deep sea is that they have a light on them. That lamp gives them convenience when they are walking or looking for food. However, Ankang fish are not born with lights, and lights will grow from small fish until love happens to them. An American scientist explained with his own experiment that it is because the ankang fish in love has a blind spot. With the deepening of love, the blind spot is getting bigger and bigger, so that both eyes can't see the road ahead. How can you live without seeing the road? We had to arrange a lamp on their backs to illuminate them. It is bioluminescence, not bioelectric current, and electric eel belongs to bioelectric current.
