dinoflagellates and diatoms). During the daytime, due to the pigmentation of the dinoflagellates, the water can turn a deep red, brown, or orange color, giving red tides their name. A bioluminescent dinoflagellate can make a flash of light inside its cell when disturbed. This light is the result of a chemical reaction using a light emitting molecule called luciferin. K. brevis, the dinoflagellate causing red tides in Florida, can cause respiratory problems, particularly for people with asthma or allergies. Red tides cause an estimated $82 million in economic 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 Bioluminescent dinoflagellates range in size from about 30 µm to 1 mm, and are found in all the world’s oceans. Occasionally they are found in high concentrations, resulting in red tides, so called because the high abundance of organisms discolors the water.

Dinoflagellates red tide

Widely distributed in temperate and subtropical waters of coastal areas, where 'blooms' can occur. This warm-water species is associated with fish and shellfish mortality events. The red tide in California is called Alexandrium tamarense. This red tide glows bright blue at night, and looks similar to the bioluminescence in Florida. However, it is a different species of dinoflagellate. The Florida red tide that occurs in the Gulf of Mexico is from an algae called Karenia brevis.

Red tides are caused by the dramatic reproduction of Karenia brevis, a species of dinoflagellate that is common in Gulf waters. Every year when conditions turn favorable, populations of the unicellular alga grow rapidly, dyeing undulating patches of water a brown, green, or rusty hue.

There are some dinoflagellates which are parasites on fish or on other protists. The most dramatic effect of dinoflagellates on life around them comes from the coastal marine species which "bloom" during the warm months of summer.

Red tides cause an estimated $82 million in economic Red tide, discoloration of sea water usually caused by dinoflagellates, during periodic blooms (or population increases). Toxic substances released by these organisms into the water may be lethal to fish and other marine life. Red tides occur worldwide in warm seas. Up to 50 million cells per litre (quart) of the species Gymnodinium brevis caused a red tide off the Florida coast in 1947 and turned the water from green to yellow to amber; thousands of fishes died.
