Evolution of Sex Change in Fish
Evolution of Sex Change in Fish Ambakisye-Okang Dukuzumurenyi 36 Views • 5 years ago

Sequential hermaphroditism occurs when an organism changes sex at some point in its life. It’s seen in a few species of gastropods and plants, but mostly fish, like napoleon wrasse, clownfish, groupers and marine angelfish. This transformation involves the complete restructuring of their gonads, as well as changes in their morphology and behaviour. For these fish, sex change is a usual part in their life cycle, and it’s one that carries adaptive advantages.
