These two strains are found to have similar niches in coastal areas. A surplus of Dinoflagellates in the night time creates a blue-green glow, however, in the day, it presents as a red brown color which names algal blooms, Red Tides. Dinoflagellates have been reported to be the cause of seafood poisoning from the neurotoxins. [41]
Karenia brevis is the causative agent of red tide, which occurs when the organism multiplies to higher than normal concentrations. During these events the water can take on a reddish or pinkish coloration, giving these explosions in the K. brevis population the name of Florida Red Tide.
Under such circumstances, they can produce toxins (generally called dinotoxins) in quantities capable of killing fish and accumulating in filter feeders such as shellfish, which in turn may be passed on to people who eat them. This phenomenon is called a red tide, from the color the bloom imparts to the
The Florida red tide organism, known as K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die.
Beachgoers could soon be seeing red off the Florida coast. A microscopic algae is growing out of control in the Gulf Coast. Although it can be toxic to marine life, some scientists are unsure if ...
Red Tide caused by dinoflagellates. Picture taken off the coast of San Diego, California. Neurotoxic shellfish poisoning (NSP) is caused by the consumption of brevetoxins, which are marine toxins produced by the dinoflagellate Karenia brevis (among several others). These toxins can produce a series of gastrointestinal and neurological effects.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Dead fish and a wretched smell that can spoil the salty breeze. When the ominous rust-colored cloud of red tide begins to saturate coastal waters in Southwest Florida, it means beach closures ...
