Abstract: Sex change occurs in a variety of animals, including fish, echinoderms,crustaceans, molluscs and polychaete worms. Here we show that the relative timing of sex change is surprisingly invariant across all animals: 91–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their maximum size. This suggests that there is a fundamental similarity across all animals, from a 2-mm-long crustacean to a 1.5-mlong fish in the underlying forces that select for sex change.
