Researchers from the National Autonomous University of Mexico have called for more to be done to fight an unwelcome visitor that continues to sail into Mexican beaches.
They are calling for a comprehensive strategy to combat the huge rafts of seaweed called Sargassum, adding that very little was known about the phenomenon.
The seaweed, which has swept into the region in part as a result of changing weather conditions, turning many once-postcard-perfect beaches into a dull pond-scum brown as it decomposes and releases a rotten egg stench, has repeated itself across the Caribbean.
It has created havoc for the tourism-dependent economies and disrupted other industries such as fisheries as fishermen struggle to navigate seaweed-choked waters.
