Toxic blooms in freshwater lakes and streams are usually caused by cyanobacteria, while blooms that occur in the ocean are typically the result of algae.
What does a harmful algae bloom look like?
Harmful algal blooms (also known as HABs) result from the rapid growth, or bloom, of algae that can cause harm to animals, people, or the local environment. They can look like foam, scum, or mats on the surface of water and can be different colors.
