Blooming cyanobacteria can produce cyanotoxins in such concentrations that they can poison and even kill animals and humans. Cyanotoxins can also accumulate in other animals such as fish and shellfish, and cause poisonings such as shellfish poisoning. Some of the most powerful natural poisons known are cyanotoxins.

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.
Species may be unintentionally disseminated through spores and fragments that hitchhike on ornamental fish and plants purchased from aquarium suppliers. [1] Algae is typically considered a nuisance and subject to removal through the use of algicides and the release of algae eaters. However, total elimination of algae is considered unlikely in a ...
The island's fringing reef has 42 hard coral genera and over 400 fish species, including the endangered humphead. The reef is also a source for larvae due to its closeness to the Pemba Channel that separates the islands from the mainland Tanzania. It provides for fishing as livelihood for the twenty Pemba communities who fish in these waters.
Dead fish or animals near the algae bloom. Skin rashes on humans after swimming in the water. Sudden sickness or death of a dog or cat, especially if algae can be seen on its legs, feet or mouth.
However their toxins are highly poisonous in large concentrations. They are capable of poisoning various species of marine life such as many fish and shellfish, and affecting the nervous system of any wildlife or humans that consume the infected marine life, or drink the contaminated water.
