Abstract

Sex reversal is common in the animal kingdom, yet nothing has thus far been known about it in amphioxus. The present study showed that female amphioxus reared in the laboratory was sexually reversed into the male, but not vice versa. This is the first report on the existence of sex change in the cephalochordate.
