The bioluminescent glow at Vieques' Mosquito Bay, one of Puerto Rico's best-known natural draws, has stopped completely, El Nuevo Día reported on Oct. 12.^[1] The bay off the island of Vieques is known for the blue-green light its waters give off at night. As of Oct. 12, that light was no longer appearing. The report does not give a cause, a timeline for how long the glow has been fading, or word on whether it may return. Those are the questions anyone who has paddled the bay will want answered next.
