How are cyanobacteria different from real ones?

Cyanobacteria, or “blue-green algae,” form a ball on the surface of the water and can produce toxins that are harmful to humans and dogs. Cyanobacteria are a group of bacteria found throughout the world. They grow in any kind of water (fresh, salt or sea) and are photosynthetic: they use sunlight to create food and survive. Typically, microscopic cyanobacteria can be seen well in warm, nutrient-rich environments that allow them to grow and bloom quickly in lakes and other bodies of water. These bacteria are commonly known as “blue-green algae” because of their color, texture and aquatic disposition, but they are not plants, but true algae.
