====Red tide====
Another cause of manatee deaths are [[red tide]]s, a term used for the proliferation, or "blooms", of the microscopic marine algae ''[[Karenia brevis]]''. This [[dinoflagellate]] produces [[brevetoxin]]s that can have toxic effects on the [[central nervous system]] of animals.<ref>{{cite journal
