Picture an ocean world so deep and dark it feels like another planet—where creatures glow and life survives under crushing pressure. This is the midwater zone, a hidden ecosystem that begins 650 feet (200 meters) below the ocean surface and sustains life across our planet. It includes the twilight zone and the midnight zone, where strange and delicate animals thrive in the near absence of sunlight.
