A chimpanzee species found to consume algae. The chimpanzee is a primate in the same family as humans and are native to sub-Saharan Africa. While many chimpanzees are naturally hydrophobic, Sakamaki (1998) found that those in Mahale have been observed to submerge themselves into freshwater and eat algae. [7]
Domoic acid can cause Amnesic Shellfish Poisoning (ASP) in humans that eat them. ASP is only a concern when algae in the ecosystem increases to high levels during an algal bloom. Shellfish are susceptible to accumulation of toxins due to their morphology as filter feeders. When they filter feed algae containing domoic acid, they can have ...
Eighty percent of the world's nations eat insects of 1,000 to 2,000 species. [6] [7] FAO has registered some 1,900 edible insect species and estimates that there were, in 2005, around two billion insect consumers worldwide. FAO suggests eating insects as a possible solution to environmental degradation caused by livestock production. [8]

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.
Cloudy water can be a warning that there are more germs in the water than normal. Discolored or smelly water could mean there is a harmful algal bloom in the water.
Sea lettuce as a food for humans is eaten raw in salads and cooked in soups. It is high in protein , soluble dietary fiber , and a variety of vitamins and minerals , especially iron . [ 5 ] However, contamination with toxic heavy metals at certain sites where it can be collected makes it dangerous for human consumption.
Some predatory algae have evolved extreme survival strategies. For example, Oxyrrhis marina can turn cannibalistic on its own species when no suitable non-self prey is available, [11] and Pfiesteria and related species have been discovered to kill and feed on fish, and since have been (mistakenly) referred to as carnivorous "algae" by the media.
