We inhabit a world in motion, but much of that world remains hidden because it happens too quickly or too slowly for humans to perceive. Take, for example, the nearly instantaneous attack of a velvet worm's slime cannon, or the almost imperceptibly slow march of battling coral colonies. The "Lens of Time" series invites viewers to time travel into the secret realms experienced by other organisms. Each episode is guided by scientists who have developed methods and technologies that allow them to capture and study stunning behaviors and structures that would otherwise remain invisible.
