View images of blooms and the effects of harmful algal blooms from around the world. While most algae are not harmful when they form “blooms,” a small percentage of algae produce toxins that can kill fish, shellfish, mammals and birds, and may directly or indirectly cause illness in people. Even blooms of non-toxic species can have harmful effects on marine ecosystems.
