Lake people, sirens and mermaids are also widespread all over the world, although they look very different in appearance. They have their own language and yet, like centaurs, they have rejected the status of persons and, at their own request, are classified as animals. The oldest recorded in history were known as sirens in Greece and in the warmer waters of the beautiful mermaids, which often appear in Muggle literature. Scottish and Irish are not so beautiful anymore.
