Red tides aren't just the scourge of beachgoers; they're also deadly to marine life like fish, birds and even manatees. And they can have a serious impact on human health, too. A red tide occurs when the population of certain kinds of algae known as dinoflagellates explodes, creating what's called an "algal bloom." Scientists sometimes refer to red tides as harmful algal blooms or HABs.
