Could you survive the real Twilight Zone?

You're traveling deep beneath the ocean's surface, where faint lights flicker and toothy grins flash. Your mission is to survive these depths and journey to the surface after sundown to feed. And as a hatchetfish, almost every other deep-sea creature is trying to eat you. Can you complete the quest? Philip Renaud and Kenneth Kostel share how to survive the ocean's Twilight Zone. [Directed by Cris Wiegandt, narrated by Addison Anderson].
