Rita Santos is a supporting character in the series Mako Mermaids, played by Kerith Atkinson.

In the trailer Rita is revealed to be principal of the Suncoast High and also a Mermaid.


At first glance, Rita seems to be the totally normal land person. But she has a secret: she's actually a mermaid. When she was younger, Rita swam with the pod off Mako Island. But she fell in love with a land person, Harry. She used to sneak off and get legs to spend time with him - until the pod discovered what she was up to. She became a pariah. So Rita made the decision to leave the pod and forged a life for herself with Harry among the land people.

Although Harry passed away, Rita has been successful on land and is now the principal of the local high school. She has survived and protected her true identity by keeping a somewhat cool and distant outer image.

Although a bit lonely sometimes, Rita has more or less adapted to her life. That is until three young mermaids turn up and ask for help. Rita is torn - she gave up mermaid life, and she doesn't want three reckless young mermaids blowing her cover. But Rita can't turn them away. As she becomes their mermaid mentor and guide, Rita discovers that although there are complications, the mermaids bring companionship and laughter back into her life. She might even start to enjoy the craziness![1]

Mermaid PowersEdit

Rita possesses the ability to transform into a mermaid ten seconds after at the touch of water. She turns back into a human a few minutes after she is out of the water and when the water on her has fully dried. Once her body is completely dry, her human form reverts back to what she appeared to be before her mermaid transformation.  She has the ability to swim at super speed of 600km/h, hold their breath for more than fifteen minutes, and possibly dive at a depth lower than any ordinary human being.
