Workers are using sargassum and sand to rebuild the beach, with shore retention and reef protection in mind.

A half-blind shark that is typically thought to live in freezing Arctic waters, scavenge on polar bear carcasses and survive for hundreds of years, recently turned up in perhaps an unexpected place—a coral reef off Belize. This marks the first time a shark of its kind has been found in western Caribbean waters off the world's second longest barrier reef.

For the fifth consecutive year, influxes of sargassum seaweed have begun piling up on beachfronts in major tourist destinations in Belize.
