In BBC Wildlife Magazine I write about the awesome fish I studied for my PhD: the Humphead Wrasse, aka Maori or Napoleon Wrasse.

They live remarkable lives on coral reefs across the Indian and Pacific Oceans, where they change sex, gather together in huge shoals to spawn and form hunting alliances with other species. Sadly, they’re becoming increasingly rare. Like the elephants of the sea, they’re being hunted towards extinction because of the price ticket on their heads. Napoleon Wrasse continue to be a delicacy in Asian seafood restaurants, where diners pay top prices, even their lips are a delicacy.
