Transfer of symbiotic luminous bacteria from parental Leiognathus nuchalis to their offspring
It is suggested that most of L. nuchalis offspring typically hatch and develop apo-symbiotically and at least 45 d after hatching, juveniles can be infected with symbiotic luminous bacteria from the light organ of adult fish, and thereby gain the ability to produce light.
