July 28, 2006—If you think you know the meaning of "night life," then you haven't gone scuba diving off the Florida Keys after dark.

Twilight on an Atlantic coral reef is like rush hour, when spiny lobsters crawl out of the crevices, porcupine fish are ready to get pumped up, and reef squid go out in search of dinner.

Join adventurous divers as they take in the evening show that is the ocean at night.
