The Seven Sirens are the members of this species that rule over the island. The other sirens that have been shown are the army of soldiers that work for them. They can either take the appearance of merfolk or some other form of aquatic life. It is unknown if all male (soldier) sirens are crustacean like beings or are hiding under armor hiding their true appearance. They appear in the Flying Fortress level.
- In ancient Greek Mythology sirens were actually partially songbirds and would sing to attract sailors into crashing their ships onto the rocky coasts of their island in order to drown them. But because they live near the sea they are always confused as a species either related to merfolk or some other form of aquatic beings. While Sirens and Mermaids are a distinct species in Shantae, both species are creatures based that are part aquatic life because of the modern interpretations of sirens.
- Some similarities may stay the same such as; both mythological sirens and Shantae sirens having their own island, one of the sirens being responsible for sinking one of the NPC's ships, and being dangerous murderous creatures. The final level being an airborne domain owned by the sirens could be a reference to how mythological sirens were flying beings but this could be coincidental.
