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.
Krill also release faecal pellets (3) whilst they feed, which can sink to the deep sea but can be consumed (coprophagy) and degraded as they descend (4) by krill, bacteria and zooplankton. In the marginal ice zone, faecal pellet flux can reach greater depths (5). Krill also release moults, which sink and contribute to the carbon flux (6).
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]
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.
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.
Pseudo-nitzschia australis is a pennate diatom found in temperate and sub-tropic marine waters, such as off the coast of California and Argentina. This diatom is a Harmful Micro Algae [1] that produces toxic effects on a variety of organisms through its production of domoic acid, a neurotoxin.
Living in Florida like being in disaster movie. Climate change -- in the form of hot oceans, toxic algae blooms -- pose challenge to state
