The ‘Living Lights’ Bioluminescence of Beautiful Saint Croix

This is the ultimate Die fröhliche Wissenschaft (Joy of the Mind) for a night-time researcher.

St. Croix is home to two rare “Super Glow” bays (Salt River and Altona Lagoon) where the water behaves like a high-frequency telemetry map.

  • Dinoflagellates: The most common microorganisms that sparkle like “stars flying past you” when the water is agitated.
  • The Green Glow (Ctenophora): Unlike the tiny white sparkles of plankton, the Comb Jelly Fish light up in neon green like a glow stick. They don’t sting, but they are fragile creatures of the “Speed-Up”.
  • Bermuda Fireworms: These provide a “Grand Pronouncement” of their own—the females release a glowing green egg sack to attract males in a synchronized lunar display.

John F. McCarthy is a veteran journalist in the Caribbean, writing from the "Decision Space" where survival meets the surreal. His reporting steel was tempered by a lineage of legendary editors and broadcasters, including Ed Wynn Brant (The Bomb), Owen Eschenroder (Ann Arbor News), Lynelle Emanuel (BVI Beacon), and Charles Thanas (WSVI-TV). Alongside longtime colleague Kenneth C. "Casey" Clark, McCarthy has navigated the front lines of the territory’s history—from the 1997 volcanic "snow" to every major hurricane since Hugo. Known for leaning out of doorless helicopters to capture the "money shot," McCarthy now edits the V.I. Free Press, providing the essential link between the island's colonial past and its SpaceX future.
