Is a siren a different name for a mermaid?
No, a Siren is a mythical bird-woman from Greek mythology, they
sing a mesmerizing song that hypnotizes sailors so they meet there
doom. A mermaid is a woman with the upper body of a human, and a
fish, eel, dolphin or snake tail, and they were a part of almost
every country's myths and tales, they even date back to the Stone
Age!
J I hope this helped.
