Description:
A beach in South Africa has been covered in black mussels in a strange phenomenon that has locals scratching their heads. The Herald Live reports that residents near Robberg Beach have been warned not to eat the mussels. Some people have blamed the incident on a red tide, a toxic alagal bloom that threatens marine life. However, Nature’s Valley Trust programme director Dr Mark Brown disputes this. “A similar event happened in November last year in the same spot,” he told the Herald. “Essentially large swells and currents break beds of mussels off the reef and they wash up. It does not appear to be linked to red tide or anything sinister at this stage.” An ecologist from SA National Parks said heavy swells and sand movement may have been a contributing factor. “Most of the mussels were still alive when they washed up, which lowers the possibility that it is related to some form of toxin from either a red algal bloom or other source,” Kyle Brown told the Herald. “As a precautionary measure, I would advise the public not to eat them.”
