If you're a big fan of mermaids, then you'll definitely want to check out Freeform's latest series, Siren, which tells the story of what happens when these half-women, half-fish creatures enter human society. You may be surprised, however, to find out that these creatures are more murder-maid than mermaid.

Siren's mermaids are fierce, apex predators of the ocean, and you most definitely do not want to find yourself in the water with them since you may just realize humans aren't quite as close to the top of the food chain as you expected. But that's just the circle of life and no reflection of the mermaids' moral intent.

"I have to clarify that we are not evil mermaids," says Sibongile Mlambo, who plays one of the mermaids."We're predators. It's just like a lion or a shark. If you happen to be in their territory and we happen to be hunting in the water, you will be hunted."

As for when they're not in the water, that's an entirely different scenario. The mermaids may not be cuddling up to humans, but they're not going to disembowel you, necessarily, once they've got two legs. As for transitioning to those legs, that's its own painful drama.

"It's a complete bone fusion, bone-breaking," series star Eline Powell tells TV Guide. "There's evolution [from fish to human] going on in a ten minute window, so it's painful and harsh."

That begs the question, of course, if transforming from a mermaid to human is so painful for them, what on earth could drag them out of the depths to make that process worth it?

Siren's two-hour premiere airs Thursday, March 29 at 8/7c on Freeform.
