What is the offspring of goddess siren?

In mythology, sirens are often depicted as enchanting creatures that lure sailors to their doom with their singing. They do not typically have offspring in the classical sense, as they are often considered to be part of the natural world rather than traditional deities with progeny. However, in some interpretations and adaptations, sirens may have offspring that inherit their alluring qualities. These offspring may be portrayed in various ways in modern literature and media, but specific lineage is not well-documented in classic mythology.
