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.
Toxic algae blooms can be extremely dangerous to both humans and pets by producing nerve and liver toxins. Nerve toxins, or nerve poisoning can cause people to experience dizziness, tingling in ...
Ingestion of saxitoxin, usually through shellfish contaminated by toxic algal blooms, can result in paralytic shellfish poisoning. [28] Saxitoxin has been used in molecular biology to establish the function of the sodium channel. It acts on the voltage-gated sodium channels of nerve cells, preventing normal cellular function and leading to ...

Many toxin-producing algal species can be found both in marine and fresh water environments when the algae are in bloom. Ichthyotoxic poisoning in humans can cause symptoms ranging in severity dependent on how much toxin was consumed.
A toxic algae bloom is injuring or killing scores of marine animals, from fish to sea lions and dolphins. Along the Southern California coast, there are deadly signs of a warming ocean. "It is ...
These shellfish are filter feeders and accumulate neurotoxins, chiefly saxitoxin, produced by microscopic algae, such as dinoflagellates, diatoms, and cyanobacteria. [1] Dinoflagellates of the genus Alexandrium are the most numerous and widespread saxitoxin producers and are responsible for PSP blooms in subarctic, temperate, and tropical ...
