genus "Lyngbya ". It is a species ofcyanobacteria that is one of the causes of the human skin irritation "seaweed dermatitis". [cite web |url=http://www.dermnetnz.org/dermatitis/plants/seaweed.html |publisher=New Zealand Dermatological Society |title=Seaweed dermatitis |date=2007-02-24 ] It is also known as fireweed.

Nutrients such as nitrogen and human waste flow to the ocean due to rain runoff and sewers. These nutrients increase the population of microbes, which in turn remove oxygen from the water. Lack of fish to eat the microbes furthers the microbe populations. Low oxygen is the environment that cyanobacteria evolved for.

This implies that pollution with phosphorous and iron may be more important than nitrogen pollution. [ Lundgren, P., et al. (2003).

"Lyngbya majuscula" produces "antifungal and cytotoxic agents, including
laxaphycin A and B andcuracin A ."
