Dinoflagellates can generate red tide when they bloom because of the high cell density in the surface water that causes a shift in color.
What is red tides?
- When microscopic algae grow to higher-than-normal densities, red tides, also known as harmful algal blooms (HABs), develop, frequently turning the water a different colour. The red tide organism, Karenia brevis, is among the more well-known HAB species in the Gulf of Mexico, which has more than 50 different HAB species.
- Microorganisms that create poisons that kill fish and render shellfish unsafe to eat are what cause this bloom, like many HABs. It may be difficult to breathe in the nearby air due to the contaminants. The name of the phenomenon implies that reddened water results from an algae bloom.
- Red tide can seriously illness those who suffer from severe or persistent respiratory disorders, such as emphysema or asthma.
