"Environmental groups in Florida are warning that unusually high numbers of manatee deaths in the first five months of the year, blamed in part on resurgent algal blooms contaminating and destroying food sources, could threaten the long-term future of the species.

The 749 fatalities recorded by the Florida Fish and Wildlife Conservation Commission (FWC) to 21 May surpassed 637 from the whole of 2020, the agency said. The total is on course to exceed the high of 804, set in 2018.

The dying off of substantial areas of seagrass, the favoured food source for the slow-moving aquatic mammals, has caused starvation. The situation has been exacerbated by the recurrence of inland blue-green algal blooms and phytoplankton blooms in Florida waterways."
