A portrait of a Siren

Sirens in the Harry Potter universe were the earliest recorded race of merpeople. They lived in Greece. Like most merpeople that live in warm water, sirens were exceptionally beautiful as compared to colder water merpeople like the Selkies and Merrows of Scotland and Ireland. It is believed that these merpeople used their singing voices to lure unwavering sailors into the water like in Muggle legend.
