Dive Into These 31 Mermaid Movies

Siren (Emmy Perry) thinks she's just an ordinary girl, but how could she be with a name like Siren? As she nears her 12th birthday, she realizes she can control water. As she starts to question her existence, she befriends Adam (Jack Grazer), who seems friendly enough, but Siren's friend Crystal (Nikki Hahn) isn't so sure. Siren soon finds out she is half mermaid and will begin her transformation on her 12th birthday. Every three years from then on, she has to return to the water to survive. Crystal, who is also part mermaid, warns her of mermaid hunters who might be out to get them.
