Two people in mermaid costumes swim underwater.

You may have thought mermaids were the stuff of cartoons and fairytales, but you’d be wrong about that. For some, it’s a career path.

The trailer above for Netflix‘s documentary MerPeople, made by the producers of Queer Eye, follows a range of people working professionally as mermaids, auditioning for the intense (and very real) training before putting on shows as part of what is apparently a half a billion dollar industry.

Like the idea of it? Well, you can always get some lessons yourself.

MerPeople drops on Netflix on May 23.
