"Wasn't this creature indirectly mentioned in the Percy Jackson Series by Rick Riordan? In the second book when they go to that place to rescue grover. Or it might have been directly mentioned...
Anyhow, in the book it is said that people who are not aware of the mythical creatures or something, refers to it as the Burmuda Triangle. It's got to do with the weird disappearance of ships and planes and such in the midst of three rocky islands. Percy Jackson goes to the sea of monsters to rescue his friend, and also ends up saving or retrieving the legendary golden fleece.

It is a very good series and I would recommend it to anyone who likes Greek mythology. :)"
