Ms. Taylor is Cleo and Lewis' science teacher in Season 3. She made five total appearances. She nearly discovered the mermaids' secret when she caught Lewis doing the experiment with the water from the Moon Pool and thought that it was a project.

Ms. Taylor suggested Lewis to apply for a scholarship to American Marine Biology Institute. Lewis did that, but didn't think he would get chosen, but he did.

Ms. Taylor also was in charge of handing out diplomas to students at the graduation.
