What is sirens greek name?

In Greek mythology, Sirens were women with the body of a large bird and the head of a woman. They were not harpies, although several depictions give them similarities to harpies. They appeared as beautiful women to sailors, and would sing beautiful songs, so the sailors would steer their ships toward them. The Sirens lived on a rocky island though, so whenever sailors passed, they would steer their ship toward the Sirens and the ship would crash and sink on the rocks. If you listened to the songs and got away alive, however, they were supposed to make you wiser.

The Greek hero Odysseus (called Ulysses by the Romans) wanted to hear their songs, so he tied himself to the mast and plugged his crew's ears with wax.

Sirens are often associated with mermaids.
