This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe. As the name suggests, the bloom of algae often turns the water red.

What algae causes red tide?
A red tide, or harmful algal bloom, is a higher-than-normal concentration of a microscopic alga (plant-like organism). In marine (saltwater) environments along Florida's west coast and elsewhere in the Gulf of Mexico, the species that causes red tides is Karenia brevis, often abbreviated as K. brevis.
Does green algae cause red tide?
Red tide is not caused by the same organism as the Lake Okeechobee algal bloom. Left: K. brevis, the species that causes red tide and associated fish kills. Right: The dominant cyanobacteria (Microcystis aeruginosa) responsible for the blue-green algal bloom in Lake Okeechobee, 2018.
Does Brown algae cause red tide?
A red tide occurs when certain types of algae—plant-like organisms that live in the water—grow out of control. The name “red tide” comes from the fact that overgrowth of algae can cause the color of the water to turn red, as well as green or brown.
The Terrifying (But Awesome) Science Behind Red Tides
Is red tide caused by human activity?
But while red tide itself is natural, scientists say there's evidence that massive blooms may be partly caused by human activities, such as fertilizers washing off farms and the discharge of fertilizer-laden water from Lake Okeechobee into the Gulf of Mexico.
What is red tide caused by?
This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe. As the name suggests, the bloom of algae often turns the water red.
What causes red and brown tide?
Brown Tides Brown (and red) tides can occur when certain algae species reach high concentrations, or "blooms," that discolor water. Some of these algae species can harm some marine life under certain conditions.
Red Tide Explained: What Is It, And Where Does It Come From?
What causes Florida red tide?
Red tide in Florida and Texas is caused by the rapid growth of a microscopic algae called Karenia brevis. When large amounts of this algae are present, it can cause a harmful algal bloom (HAB) that can be seen from space.
What is the main cause of red tide?
What Causes a Red Tide? Red tides are caused by algae, which are tiny, microscopic organisms that grow in the water. Almost all bodies of water have some algae, but in a red tide, there is a lot more algae in the water than usual.
What Causes Red Tides?
Are red tides caused by humans?
But while red tide itself is natural, scientists say there's evidence that massive blooms may be partly caused by human activities, such as fertilizers washing off farms and the discharge of fertilizer-laden water from Lake Okeechobee into the Gulf of Mexico.
What causes red tide to form?
This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe. As the name suggests, the bloom of algae often turns the water red.
